1.0 SAFETY PRECAUTIONS
Read this manual thoroughly, paying special attention to the sections that apply to you, before
working with the UPS. R et a in t h is m a n u a l for u se b y in st a llin g p er son n el.
Under typical operation and with all UPS doors closed, only normal safety precautions are neces-
sary. The area around the UPS system should be kept free from puddles of water, excess mois-
ture, or debris.
Special safety precautions are required for procedures involving handling, installation, and main-
tenance of the UPS system or the battery. Observe all safety precautions in this manual before
handling or installing the UPS system. Observe all precautions in the Op er a t ion a n d Ma in t e-
n a n ce Ma n u a l, before as well as during performance of all maintenance procedures. Observe all
battery safety precautions before working on or near the battery.
Th is eq u ip m en t con ta in s sever a l cir cu its th a t a r e en er gized w ith h igh volt a ge. Only test
equipment designated for troubleshooting should be used. This is particularly true for oscillo-
scopes. Always check with an AC and DC voltmeter to ensure safety before making contact or
using tools. Even when the power is turned Off, dangerously high potentials may exist at the
capacitor banks and at the batteries.
ONLY q u a lified ser vice p er son n el sh ou ld p er for m m a in ten a n ce on th e UP S syst em .
When performing maintenance with any part of the equipment under power, service personnel
and test equipment should be standing on rubber mats. The service personnel should wear insu-
lating shoes for isolation from direct contact with the floor (earth ground).
Unless all power is removed from the equipment, one person should never work alone. A second
person should be standing by to assist and summon help in case an accident should occur.
Four types of messages are used throughout the manual to stress important text. Carefully read
the text below each Danger, Warning, Caution, and Note and use professional skills and prudent
care when performing the actions described by that text.
A Da n ger signals immediate hazards resulting in severe personal injury or death. For example:
DANGE R
A DANGE R SIGNALS IMMEDIATE H AZAR DS WH ICH WILL
R ESULT IN SEVE R E P ER SONAL INJ UR Y OR DE ATH .
A Wa r n in g signals the presence of a possible serious, life-threatening condition. For example:

TO DO SO COULD R E SULT IN SE RIOUS INJ UR Y OR DEATH . DO
NOT WOR K ON OR OP ER ATE TH IS E QUIP ME NT UNLESS YOU
AR E F ULLY QUALIF IE D TO DO SO!! NE VE R WOR K ALONE .
A Ca u t ion indicates a condition that could seriously damage equipment and possibly injure per-
sonnel. For example:
CAUTION
Ext r em e ca r e is n ecessa r y w h en r em ovin g sh or in g b r a ces. Do n ot
str ik e t h e ca b in et w ith h a m m er s or ot h er tools.
A Note emphasizes important text. If the note is not followed, equipment could be damaged or
may not operate properly. For example:
NOTE
If the UPS system has a blown fuse, the cause should be determined before
you replace the fuse. Contact Liebert Global Services.

2.0 INSTALLATION CONSIDERATIONS
Install your Series 600T UPS in accordance with the submittal drawing package and the follow-
ing procedures.
A Liebert authorized representative must perform the initial system check-out and start-up to
ensure proper system operation. Equipment warranties will be voided unless system start-up is
performed by a Liebert authorized representative. Contact your local Liebert sales representative
or Liebert Global Services at 1-800-543-2378 to arrange for system start-up.
CAUTION
R ea d t h is m a n u a l t h or ou gh ly b efor e a tt em p t in g t o w ir e or
op er a t e th e u n it . Im p r op er in st a lla t ion is t h e m ost sign ifica n t
ca u se of UP S st a r t -u p p r ob lem s.

p r efer a b le to in sta ll t h e UP S in a r est r ict ed loca t ion t o p r even t
a ccess b y u n a u t h or ized p er son n el.
1. Proper planning will speed unloading, location, and connection of the UPS. R efer t o
2. Refer to information later in this manual regarding the optional Battery Cabinets and
Transformer Cabinets. Ob ser ve a ll b a t ter y sa fety p r eca u t ion s w h en w or k in g on or
n ea r t h e b a t ter y.
3. Use the shortest output distribution cable runs possible, consistent with logical equipment
arrangements and with allowances for future additions if planned.
4. Recommended ambient operating temperature is 25°C (77°F). Relative humidity must be less
than 95%, non-condensing. Note that room ventilation is necessary, but air conditioning may
not be required. Maximum ambient operating temperature is 40°C (104°F) without derating.
The batteries should not exceed 25°C (77°F). At elevations above 4,000 feet (1219 meters)
derating may be required (consult your Liebert sales representative).
5. Even though your Liebert UPS unit is at least 93% efficient, the heat output is substantial.
environmental conditioning systems can accommodate this BTU load, even during utility
outages.
6. The routing (inside the facility) to the installation site, as well as the floor at the final
equipment location, must be capable of supporting the cabinet weight and the weight of any
moving equipment. The modules weigh up to 12,000 pounds. The battery cabinets weigh
between 3000 and 4900 pounds. The System Control Cabinets weigh between 1000 and 2550
7. Plan the routing to ensure that the unit can move through all aisleways, doorways, and
around corners without risking damage. If the modules and batteries must be moved by
elevator, check the size of the door openings and the weight-carrying capacity of the elevator.

Types of System Control Cabinets
1. SCCT is a stand-alone cabinet containing system control logic for up to six UPS modules,
static bypass switch, manually operated disconnects for the static bypass switch, and two
motor-operated system breakers. The SCCT is painted the same color as the Liebert UPS, but
does not match the sheet metal style of the UPS.
2. SCCI has the system control logic, circuit breakers and static bypass switch integrated into a
switchboard cabinet manufactured by others.
3. SCCC is an integrated configuration like the SCCI with the static bypass switch rated for
continuous duty.

carrier and to Liebert Global Services immediately.
4. Check the nameplate on the cabinets to verify that the model numbers correspond with the
one specified. Record the model numbers and serial numbers in the front of this installation
manual. A record of this information is necessary should servicing become required.
4.2
Internal Inspections
1. Verify that all items have been received.
2. If spare parts were ordered, verify arrival.
3. Open doors and remove cabinet panels to check for shipping damage to internal components.
4. Check for loose connections or unsecured components in the cabinet(s).
5. Check for installation of circuit breaker line safety shields. There should be no exposed circuit
breaker terminals when the cabinet doors are opened.
6. Check for any unsafe condition that may be a potential safety hazard.
7. UPS modules are shipped with internally mounted shipping brackets. The shipping brackets
(painted orange) must be removed from the rear (remove rear panels).

6.2
Matching Battery Cabinets
Two sizes of optional battery cabinets are available. Refer to F igu r e 16 to F igu r e 18. The battery
cabinet cells range from 90 to 150 Ampere-hours. The same model battery cabinet may be paral-
leled in multiple cabinet strings for additional capacity. Battery capacity (in minutes) at your
installation will depend on cabinet model, number of cabinets, and amount of critical load on the
UPS.
1. H a n d lin g. The Battery Cabinet weighs 3000 to 4900 pounds. Forklift slots are provided for
easy handling.
2. Ca b in et In sp ect ion . Remove all panels and visually inspect the batteries, bus connections,
and cabinet for any damage. Exer cise ca u tion ; volt a ge is p r esen t w it h in t h e Ba t t er y
Ca b in et even b efor e in st a lla t ion . If there are signs of damage, do not proceed. Call Liebert
Global Services at 1-800-543-2378.
3. Ba tt er y St or a ge. The batteries used in the Battery Cabinet have an excellent charge
retaining characteristic. The batteries can be stored for up to six months without any
appreciable deterioration. Self-discharge rate of the batteries is approximately 3% per month
when the batteries are stored in temperatures of 15°C to 25°C (59°F to 77°F). If the Battery
Cabinet is planned to be stored for longer than six months, contact Liebert Customer Service
for recommended action.
4. In sta lla tion . The Battery Cabinet(s) can be located conveniently next to each UPS module.
The front-access-only-design eliminates side and rear service clearance requirements.
• En vir on m en t . Locate the Battery Cabinet in a clean, dry environment. Recommended
temperature range for optimum performance and lifetime is 20°C (68°F) to 25°C (77°F).
• Ser vice Clea r a n ce. Allow front access to the Battery Cabinet at all times for mainte-
nance and servicing. Electrical codes require that the Battery Cabinet be installed with no
less than 3 feet (1 meter) of clearance at the front of the cabinet when operating. Side and
rear panels do not require service clearance.
• Sid e P a n els. Remove protective side panels to connect cabinets together. Panels are
retained at the bottom with three screws.
• Sh ield P la t e. If the Battery Cabinets are bolted to the side of the UPS module, the shield
plate inside the Battery Cabinet should be on the side toward the UPS module for proper
UPS airflow. Move the shield if required by your Battery Cabinet location.
• Ca b les. Cables may be run between the cabinets through cutouts in the top of the cabi-
net, eliminating the need for external conduit runs. R ou t e ca b les b efor e m ovin g ca b i-
n et s in to fin a l p osit ion for b olt in g t oget h er . Remove top panels for access, if
required. No top or bottom entry cables are required, except for remotely located cabinets
• Bu ilt -In Ca b in et s. Matching Battery Cabinets are designed as a bolt-on section to the
side of the UPS module cabinet. Use bolts (3/8"-16 x 1-1/4") to connect cabinet frames at
posts, two places front and two places rear. Brackets are provided to make rear connec-
tions easier from inside the cabinet.
6.3
Non-Standard Batteries
When batteries other than a matching Battery Cabinet are used (not recommended), a remote
battery disconnect switch with overcurrent protection is required per the National Electrical
this option.
1. Install battery racks/cabinets and batteries per manufacturer’s installation and maintenance
instructions.
2. Verify battery area has adequate ventilation and battery operating temperature complies
with manufacturer’s specification.
If you have any questions concerning batteries, battery racks, or accessories, contact Liebert Glo-
bal Services at 1-800-543-2378.

7.0 CONFIGURING YOUR NEUTRAL AND GROUND CONNECTIONS
Improper grounding is the largest single cause of UPS installation and start-up problems. This is
not an easy subject, since grounding techniques vary significantly from site to site, depending on
several factors. The questions you should ask are:
• What is the configuration of the input power source? Most of the recommended schemes for
UPS grounding require grounded-wye service. The UPS system requires a bypass neutral for
sensing and monitoring the quality of the bypass input. If the building service is straight
delta or corner-grounded delta, contact your Liebert representative for details of the Artificial
Neutral or Isolated Neutral kits for the System Control Cabinet.
• What are the UPS input and output voltages? Systems with 480 VAC input and output have
significantly different needs than systems with 208/208 VAC.
• What is the connected load? Does the critical load consist of one or more Power Distribution
Units (PDUs)? Do the PDUs have isolation transformers?
The following sections discuss recommended grounding procedures for various system configura-
tions.
NOTE
Some UPS modules are equipped with input isolation transformers.
However, these transformers have no effect upon any system grounding
considerations. These modules will be grounded exactly as shown in the
following examples.

7.1
Preferred Grounding Configuration, 480 or 600 VAC Input and Output, Isolated
Power Distribution Units, Wye-Connected Service
Figure 3 Preferred Grounding Configuration, 480 or 600 VAC Input and Output
The most-common configuration of Series 600T UPS Multi-Module Systems is with 480 VAC
input, 480 VAC output, and a connected load consisting of multiple Power Distribution Units
(PDUs) with isolation transformers in the PDUs to produce 208 VAC. For Canadian customers,
the UPS modules usually have 600 VAC input and output. The same principles apply if the con-
nected load is an isolation transformer feeding various loads. Figure 3 above shows a typical
installation. The Maintenance Bypass Switchgear is shown separately for clarity, but is usually
contained within the System Control Cabinet (SCC).
Notice that the UPS module input and the system bypass input are connected to a grounded-wye
service. In this configuration, the UPS module is not considered a separately derived source.
All of the UPS module output neutrals are solidly connected to the SCC neutral. The SCC neutral
is solidly connected to the building service neutral, which is bonded to the grounding conductor at
the service entrance equipment.
The isolation transformers in the PDUs can be considered separately derived sources. Therefore
the PDU neutrals should be bonded to the PDU grounding conductor and connected to a local
grounding electrode in compliance with NEC 250-26.
NOTE
Impedance-grounded wye sources require an Isolated Neutral Kit in
addition to the grounding and neutral conductors shown above.

7.2
Grounding Configuration, 480 or 600 VAC Input and Output, Delta Source
Figure 4 Grounding Configuration with Ungrounded Delta Source Input
As previously mentioned, Series 600T UPS systems require a bypass input netrual for sensing
and monitoring. With a wye-connected input source, the installer should always connect the
building service neutral to the System Control Cabinet (SCC) output neutral to achieve this.
When the building service is delta-connected, however, the installer must take special steps to
ensure reliable UPS functioning.
If building service is ungrounded delta (and there is no intent to operate with one corner of the
delta grounded, either on purpose or accidentally), the SCC requires the Series 600T Artificial
Neutral Kit for proper operation. This kit uses a resistor network to create a reference point for
the bypass input. In this case, the SCC output neutral must be bonded to the SCC ground.
If the building service is corner-grounded delta or an Impedance-grounded wye, the SCC requires
the Isolated Neutral Kit. This kit uses control isolation transformers to create a reference point.
For this application, the SCC output neutral must not be bonded to the SCC ground.
NOTE
The Artificial Neutral Kit introduces a maximum current of 0.3 amps to
ground. Take care to ensure that this does not interfere with the operation
of any upstream ground-fault detection devices.

Preferred Grounding Configuration with Power-Tie Switchgear
Figure 5 Preferred Grounding Configuration, Power-Tie Systems
Multi-Module Systems can be used with Power-Tie switchgear to provide dual critical load busses.
The Power-Tie switchgear permits transferring critical loads from one critical bus to the other so
that one UPS system and associated breakers can be de-energized for maintenance. Certain con-
figurations of Power-Tie equipment also permit the operator to continuously parallel the output of
both UPS systems.
In tied systems, each SCC must have its neutral solidly connected to the Power-Tie switchgear
neutral. The UPS modules, as usual, must have their output neutrals solidly connected to their
respective SCC neutrals. There should not be a connection between the service entrance neutral
and either the SCC or module neutrals.
NOTE
It is essential to run a neutral connection between the tie switchgear and
both SCCs as shown in the illustration above.

Grounding Configurations, Battery Systems
Figure 6 Battery Cabinet Grounding Configuration
Large, open-rack battery systems are normally either locally grounded or left ungrounded,
depending on local code requirements.
Battery cabinet systems, on the other hand, should be grounded to the UPS module ground bus.
The figure above illustrates how a simple one-cabinet system would be grounded. For systems
with multiple cabinets, the same configuration would apply. However, for simplicity the installer
can connect all the battery cabinet grounds for a particular module together and run a single
ground conductor to that UPS module ground.

8.1
Power Wiring
1. Power wiring must be run in individual, separate conduits or cable trays. Refer to the Outline
locations of the various power connections within the UPS and SCC. In particular, note the
location of the rectifier input power connections.
CAUTION
P ow er a n d con t r ol w ir in g m u st b e sep a r a t ed !
2. Observe local, state and national electrical codes. Verify utility power and its overcurrent
protection rating will accommodate the UPS input rating, including battery recharging.
3. A safety ground wire must be run from building ground to ground point in the UPS Module
Cabinets, the System Control Cabinet, and the Power-Tie Cabinet (if applicable). See Sections
7.1 through 7.4. The grounding conductor shall comply with the following conditions of
installation:
a. An insulated grounding conductor must be sized in accordance with the NEC and local
codes. It must be green (with or without one or more yellow stripes) and be installed as
part of the branch circuit that supplies the unit or system.
b. The grounding conductor described above is to be grounded to earth at the service
equipment or, if supplied by a separately derived system, at the supply transformer or
motor-generator set in accordance with the instructions in Section 7 of this Manual.
c. The attachment-plug receptacles in the vicinity of the unit or system are all to be of a
grounding type, and the grounding conductors serving these receptacles are to be
connected to earth ground at the service equipment.
4. When possible, input to the UPS and bypass should be four wire plus ground. When input is
straight delta, the UPS artificial neutral kit should be ordered. When input is corner-
grounded delta, the isolated neutral kit should be ordered.
5. Observe clockwise phase rotation of all power wiring. Phase A leads Phase B leads Phase C. A
qualified electrician should check the phase rotation.
6. Power cables must be rated for less than 2 volts line drop at maximum rated system current.
7. If site equipment includes a backup generator and automatic transfer switch(es), consult the
manufacturers of those devices for information on sizing and interfacing to the UPS system.
8. The installing contractor can remove the access plates from the left and right side of the cable-
access area in the top of the UPS in order to cut entry holes for conduit. For units that also
have bottom cable access, there is a third access plate on the right side of the module.

8.2
Control Wiring
Control wiring must be stranded and tinned and run in individual separate steel conduits. Con-
trol wiring must be separated from power wiring. In addition, each control wiring cable group
should be run in a separate conduit to minimize control signal interference.
Refer to the Control Connection Locations and Control Wire Lists, F igu r e 33 through F igu r e 52.
Notice that there are nine cable groups in a typical system:
• Cable group 1 carries signals for the Module Battery Disconnect.
• Cable group 2 is for the remote communications options: modem, remote terminal and remote
CRT.
• Cable group 3 carries signals for the Remote Emergency Module Off and Remote Emergency
Power Off.
• Cable group 4 carries signals for the optional Remote Status Panel.
• Cable group 5 is for the optional SiteScan system.
• Cable group 6 carries signals for the reduced battery charge limit and the reduced input cur-
rent limit.
• Cable group 7 carries signals to and from the maintenance bypass switchgear.
• Cable groups 20 and 21 carry signals for general housekeeping, modules to SCC.
Other cable groups will be required for other optional equipment. If your system has any installed
options, special wire lists will be included in your Submittal Drawing Package. Contact your Lie-
bert Sales Representative for assistance if the submittal drawings have been lost or misplaced.
Figures AA and BB show the typical location of control connections inside the UPS and SCC. The
position of a particular control connection may be different for your system, depending on the
model and the installed options.
NOTE
The UPS control and communication wiring are considered Class 2
circuits by NEC standards. However, NEC Class 1 wiring methods are
required for these circuits to ensure proper operation of the UPS.

12.0 APPENDIX A - SITE PLANNING DATA
500-750kVA Multi-Module Systems
12.1 Notes
1. Nominal rectifier AC input current (considered continuous) is based on full rated output load.
Maximum current includes nominal input current and maximum battery recharge current
(considered noncontinuous). Continuous and noncontinuous current limit are defined in NEC
100. Maximum input current is controlled by current limit setting which is adjustable. Values
shown are for maximum setting of 125%. Standard factory setting is 115%.
2. Nominal AC output current (considered continuous) is based on full rated output load.
Maximum current includes nominal output current and overload for 10 minutes.
3. Bypass AC input current (considered continuous) is based on full rated output load.
4. Feeder protection (by others in external equipment) for rectifier AC input and bypass AC
input is recommended to be provided by separate overcurrent protection devices.
5. UPS output load cables must be run in separate conduit from input cables.
6. Power cable from module DC bus to battery should be sized for a total maximum 2.0 volt line
drop (measured at the module) at maximum discharge current.
7. Grounding conductors to be sized per NEC 250-122. Neutral conductors to be sized for full
capacity for systems with 4-wire loads and half capacity for systems with 3-wire loads. NOTE:
A neutral conductor is required from each Multi-Module Unit output to the System Control
Cabinet.
8. Rectifier AC Input: 3-phase, 3-wire, plus ground
AC Output, SCC to Load: 3-phase, 3 or 4-wire, plus ground
Bypass AC Input: 3-phase, 3 or 4-wire, plus ground
Module DC Input from Battery: 2-wire, (positive and negative)
9. All wiring is to be in accordance with National and Local Electrical Codes.
10. Minimum clearance is 2 feet above UPS.
11. Top or bottom cable entry through removable access plates. Cut plate to suit conduit size.
12. Control wiring and power cables must be run in separate conduits. Control wiring must be
stranded tinned conductors.
13. 7% maximum input harmonic current and 0.92 lagging input power factor at full load with 6-
pulse rectifier and optional input filter (4% with 12-pulse rectifier and input filter).
30% maximum input harmonic current and 0.85 lagging input power factor at full load
without optional input filter (9% with 12-pulse rectifier).
14. Dimensions and weights do not include the System Control Cabinet required for Multi-
Module Systems.
