(see figure 1)
■ the normal AC input and the bypass AC
input have different functions and,
depending on the installation, may be pro-
tected differently upstream and/or come
from different sources.
■ when increased power is required, sev-
eral Galaxy PW™ units may be connect-
ed in parallel (up to four). In this configura-
tion, an "isolation" function is added for
the UPS system as a whole for mainte-
nance purposes, without interrupting the
supply of power to the load.
■ a rectifier/charger module (A) converts
3-phase AC power from the normal AC
source supply (1) into DC power for the
normal inverter input and float charges or
recharges the battery;
■ a battery unit (D) provides backup
power for the inverter in the event of a
voltage drop or a normal AC source fail-
ure;
■ an inverter module (B) converts the DC
power supplied by the rectifier/charger
module or the battery unit into 3-phase AC
power for the load;
■ a static bypass module (C) ensures the
instantaneous transfer of the load to the
bypass AC source input in the event of an
inverter shutdown (initiated by the user or
by a protective device) or a sudden over-
load;
■ a maintenance bypass isolates the UPS
for maintenance and transfers the load to
bypass AC source input without interrupt-
ing the supply of power. The maintenance
bypass is made up of three manual
switches (Q3BP, Q4S and Q5N).

operation with the normal AC battery time
source down
operation in on-line
mode
The available battery time during a normal
AC source outage depends on the:
■ rated capacity of the battery;
See figure 6.
In the event of a normal AC source failure
or voltage outside specified tolerances of
±10% in amplitude (±15% optionally), the
rectifier/charger (A) stops and the battery
(D) supplies the necessary backup power
to the load via the inverter (B). The bat-
tery, float-connected between the rectifi-
er/charger and the inverter, discharges
during this operating mode.
normal operation
Normal AC source power is available (see
figure 5).
■ lights 1 , 4 and 5 shine green on
the control panel;
■ the power necessary for the load is pro-
vided by the normal AC source (1) through
the rectifier/charger (A) and the inverter
(B);
■ the rectifier/charger (A) also supplies
the power to float charge and recharge the
battery if any.
The rectifier/charger output voltage (DC) is
regulated to supply:
❏ the float-charging or the recharging volt-
age for vented lead-acid or Ni/Cd batter-
ies,
❏ a single charge voltage for sealed lead-
acid batteries.
■ power consumed by the load;
■ temperature of the battery;
■ age of the battery.
The specified battery time corresponds to
a minimum duration at full rated load.
The actual backup time can therefore be
greater if the system operates below its
full rated load during the normal AC
source outage. Operation on battery
power can be extended beyond the speci-
fied time by reducing the load power con-
sumption (by disconnecting non-critical
loads).
A "low battery" warning signal is sent via
volt-free changeover contacts for remote
control devices when the battery voltage
reaches a level slightly above the mini-
mum level. This signal warns the user of
the imminent end of battery power. On the
device itself, the buzzer beeps rapidly.
The message "LOW-BATTERY SHUT-
DOWN WARNING" is displayed, followed
by the remaining backup time and the per-
cent load. Light 2 turns red and flashes.
Battery power stops when the voltage
supplied by the battery reaches the mini-
mum threshold. This results in inverter
shutdown and transfer of the load without
interruption to the bypass AC source. Light

TECTED, BATTERY DISCHARGING", fol-
lowed by the remaining backup time and

This information is also available via volt-
free changeover contacts for remote con-
trol devices.
The voltages depend on the number of
battery cells and the battery manufacturer.
Factory set, they may also be adjusted by
after-sales support technicians.

sures the battery temperature and auto-
matically adjusts the voltages.

The battery charge cycle takes place in
two steps (see figure 8):
operation with the normal AC
source restored
NOTE
■ step 1: the battery is recharged at a
constant current limited to 0.1C10 (i.e.
1/10th of the battery capacity specified for
a 10 hour discharge). The DC voltage
increases with the battery charge until the
charge level is reached;
■ step 2: the battery is recharged at con-
stant voltage equal to the charge level.
The charging current gradually decreases
until reaching a specified low value (float-
ing current).
For vented lead-acid batteries, the rectifi-
er/charger supplies the charging voltage
for 0 to 255 hours (parameter defined by
the after-sales support department) and
then the floating voltage. For sealed lead-
acid batteries, the charging and floating
voltages are the same.
If the normal AC source
failure is shorter than 0 to
255 seconds (default value
= 30 seconds) (parameter
defined by after-sales sup-
port department), the
charger automatically sup-
plies the floating voltage
given the low battery dis-
charge.
See figure 7.
When normal AC source power (1) is
restored or its voltage returns to within
specified tolerances, the system automati-
cally returns to its normal operating mode
described above (on the condition it did
not reach the end of battery power). If the
end of battery power was reached (with
the resulting inverter shutdown), the rectifi-
er/charger (A) restarts automatically, but
the inverter (B) must be restarted manual-
ly.
The rectifier/charger recharges the battery
(D) which was discharged during the
mains outage. During battery charging,

If the conditions are not satisfied, the
inverter will current limit to 165% of its
rated current for 1 second before stop-
ping;
■ in the event of a small but extended
overload (i.e. a continuous level of power
exceeding the full rated load), the inverter
will continue to supply power for a period
depending on the magnitude of the over-
load (10 minutes for a 125% overload, 1
minute for a 150% overload). See the
overload curve in figure 10;
■ in all three of the above cases, inverter
shutdown and supply of the load via the
bypass AC source results in the following
on the control panel:
❏ light 4 goes off,
❏ activation of the buzzer (continuous
beep),
parallel UPSs with redundancy
inverter shutdown or
overload
See figure 9 for devices or installations
operating in on-line mode with a bypass
AC source.
■ the shutdown of one UPS unit is of no
consequence for the load. The others
each take up an equal amount of load
power and the load continues to be sup-
plied normally;
Unit shutdown results in the following on
the control panel:
❏ lights 4 and 5 go off,
❏ activation of the buzzer (continuous
beep),
❏ the message "LOAD NOT PROTECT-
ED, PARALLEL ON-LINE MODE" is dis-
played;
■ in the event of an overload, the system
only loses its redundancy as long as the
overload is less than the total rated power
of the functioning units. If the overload is
greater, the operating mode is that previ-
ously described for systems without
redundancy.

■ in the event of a UPS shutdown (initiat-
ed by the user or by an internal protective
device), the load is automatically trans-
ferred to the bypass AC source. If transfer
conditions are satisfied, transfer takes
place instantly, without interruption to the
load;
Note: transfer conditions are not satisfied
when bypass AC source characteristics
are outside tolerances (voltage: ±10%; fre-
quency as per personalization; phase sync
with inverter ±3°);
The shutdown of one inverter results in
overload on the other inverters in opera-
tion. Two cases may then arise:
■ if the overload on each remaining invert-
er is > than 1.65 ln, the load is immediate-
ly transferred to the bypass AC source;
■ if the overload is less than 1.65 ln, the
remaining inverters support the overload
(see curve in figure 14), and the load is
transferred to the bypass AC source;
■ after this transfer:
❏ the light 4 goes off,
■ in the event of a major transient over-
load (greater than 1.65 In), immediate
transfer takes place as above, without
interruption to the load.
The return to the inverter is automatic
when the overload disappears if the num-
ber of possible returns has not been
reached (0 to 255, programmable by per-
sonalization). If this number has been
reached, the load continues to be supplied
by the bypass AC source. This operating
mode allows start-up of load devices
causing high inrush currents.

operation with an engine output voltage quality
When the bypass AC source frequency
returns to within the specified tolerances,
the inverter is gradually re-synchronized to
the bypass line at a rate of 0.5 Hz to 2
Hz/s (as per the value personalized by the
after-sales support department), thus
avoiding exposing the load to sudden fre-
quency variations.

regulation
For stable or slowly varying load condi-
tions, the inverter output voltage is regu-
lated to within ±0.5% in amplitude.
The frequency of the output voltage can
theoretically be regulated to within 0.1% of
the rated value, however the output fre-
quency range may be intentionally extend-
ed to a maximum of ±2 Hz so that the
inverter can remain synchronized with the
bypass AC source and its inherent fre-
quency fluctuations, thus enabling transfer
of the load to the bypass line at any time.
transient voltage regulation
The inverter output voltage is not notably
affected by instantaneous major variations
in load characteristics.
This is made possible by the PWM (Pulse
Width Modulation) chopping technique
and the microprocessor-based regulation
system that instantly compensates for any
variation. In particular, the inverter output
voltage remains within +/- 2% of the rated
voltage for load step changes of 0 to
100% or of 100 to 0%.
sary for starting and bringing on line the
stand-by generator. The battery (D) sup-
plies power to the inverter (B) during the
transfers:
■ normal AC source to the generator;
■ generator to the normal AC source.
The transfer sequences described above
(normal AC source ➜ battery, battery ➜
generator, generator ➜ battery, and bat-
tery ➜ normal AC source) are fully auto-
matic. They in no way affect the load and
require no manual operation by the user.
NOTE
NOTE
The output frequency
range can be personalized
and if necessary modified
on the customer site by a
qualified MGE UPS SYS-
TEMS support technician
from ±0.25 Hz to ±2 Hz in
0.25 HZ steps.
To avoid load surges on
the generator, the rectifi-
er/charger is started with
a 10 second maximum
current consumption
walk-in (lasting 3 to 10
seconds, depending on
the percent load).
When the bypass AC
source voltage moves out-
side this frequency range,
the inverter is desynchro-
nised and operates in
"free running" mode, with
the output frequency regu-
lated to a high level of
accuracy by a quartz
oscillator.
To avoid overloading an
undersized engine gener-
ator set, it is possible to
set a maximum power
level drawn by the nor-
mal AC input. Any addi-
tional power required is
supplied by the battery.

User’s Manual
Terminals XR2, XR3, XR4 and XR5 on the
"Media Contacts 11" board of each type of
unit can be used to receive signals from
the operating environment and to transmit
signals concerning the operating status of
the UPS (see figure 16 for the position of
the board, item 12).
■ signal to open battery circuit break-
er(s) QF1 in the event the "emergency off"
button is pressed or to avoid an excessive
battery discharge (lasting more than three
times the rated backup time plus two
hours);
■ repo contact (volt-free changeover con-
tact) used to trip switching devices in the
event of an emergency shutdown.
■ "general alarm" information (volt-free
changeover contact) which includes:
❏ internal faults,
❏ information on temperatures outside tol-
erances in the battery room (optional),
❏ overload information (> In),
❏ static-switch ventilation and power-sup-
ply faults.
signal transmission
■ an auxiliary 24 V power supply, isolat-
ed and backed up, is used to supply:
❏ the undervoltage release of the battery
circuit breaker(s) QF1,
❏ the board that measures the tempera-
ture in the battery room;
■ "low battery" warning signal (volt-free
changeover contact) indicating that battery
time is about to run out. The warning
threshold may be personalized;
■ "load on UPS" signal (volt-free
changeover contact) indicating that the
load is supplied by the inverter. For a sin-
gle-UPS unit, one volt-free changeover
contact may be used to indicate that the
load is supplied by the bypass AC source;
■ "load on battery power" signal (volt-
free changeover contact) indicating that
the inverter is supplied by the battery in
the following cases:
signal reception
The signals should be provided by volt-
free contacts.
■ emergency off:
An NC contact causes shutdown of the
inverter and the rectifier/charger, opening
of the battery circuit breaker, blocking of
the static bypass and activation of a relay
contact on the "Media Contacts 11" board;
■ battery room ventilation fault:
An NO contact causes shutdown of the
rectifier/charger;
NOTE
The maximum breaking
capacity of the
changeover contacts is
5A at 250V.
■ battery circuit breaker QF1 closed:
An NO contact prevents inverter start-up if
the circuit breaker is open;
❏ normal AC source outage or voltage
drop,
❏ rectifier/charger shutdown,
■ battery temperature:
A PC-board, placed near the battery, sup-
plies information on the battery tempera-
ture, thus enabling the rectifier/charger to
regulate the battery voltage;
■ "auxiliary" signals:
Depending on the selected settings, these
signals may be used to provoke:
❏ forced shutdown of the inverter (whatev-
er the status of the bypass AC source),
❏ protected shutdown of the inverter (load
transfer to the bypass AC source).
❏ limiting of the current drawn by the recti-
fier/charger (programmable value) when
supplied by an engine generator set with
an insufficient power rating. The additional
power required by the inverter is supplied
by the battery which discharges,
❏ rectifier/charger current limiting.
This signal, which may be used to initiate
process saving and shutdown procedures,
is time-delayed 30 seconds to avoid
unnecessary operations following micro-
breaks;
■ "maintenance position" signal (volt-

❏ inverter output switch Q5N is open,
❏ battery circuit breaker QF1 is open;
❏ limiting of the battery charge current
(programmable value) if the normal AC
source is replaced by an engine generator
set with an insufficient power rating.

The battery capacity is the value mea-
sured by the UPS microprocessor. It is
expressed in Ampere-hours. This value
changes over time depending on the para-
meters of the battery itself and its environ-
ment. This measurement is used to check
that the battery is capable of supplying the
rated power in the event of a mains out-
age.

bypass (see "maintenance bypass" in the
"Alarm" section);
■ clean the system regularly, particularly
the air filter inlet and outlet grills. Check
that the air circulates freely in the cabi-
nets. Use a vacuum cleaner if necessary;
■ check that nothing hinders the ventila-
tion at the top and at the back of the sys-
tem.
■ vented lead-acid batteries:
❏ check the electrolyte level regularly and
add water if necessary,
❏ check the voltage of each cell to deter-
mine if it is necessary to equalize the bat-
tery,
❏ check the terminals of each cell and
clean if necessary.
CAUTION
Battery maintenance is
undertaken with the system
powered up. Operations must
be carried out in accordance
with applicable safety regula-
tions by qualified personnel
using insulated tools, gloves
and safety goggles.
Batteries contain danger-
ous substances that will harm
the environment if thrown
away. If you change the bat-
teries yourself, call on quali-
fied organizations for battery
recovery and recycling.

This electronic board provides user
access to the J-Bus communications pro-
tocol. Using the data and address tables
provided, the user can customize his
installation.
For example, MAC address 00 80 C8 AB
AA 01 is related to IP address

GTC + software
The user has access to the J-Bus protocol
and, in addition, the associated software
acquires system parameters (measure-
ments, status conditions) and transforms
them into diagrams, alarm messages and
tables. With the click of a mouse, the user
can locally or remotely supervise the UPS
system (comprising one or many UPS
units).
Two-channel network board
This electronic board comprises two ports,
each of which may be user set, either for
the U-Talk protocol or as a relay contact.
U-Talk is the protocol required to establish
contact with the communications software.
Relay contacts may be used for specific
network applications (IBM AS400, Novell,
etc.).

networks
Integrated SNMP agent
This electronic board, installed in the UPS
system, enables direct connection to all
Ethernet networks using TCP/IP.
The UPSs may then be supervised via the
computer network. Furthermore, they can
be used to close system files without hav-
ing to add an external SNMP agent.
This board is fully compatible with
