GENERAL

As with other types of high power equipment, dangerous voltages are present within

the UPS and battery enclosure. The risk of contact with these is minimised as the live

component parts are housed behind a hinged, lockable door. Further internal safety

screens make the equipment protected to IP20 standards.

No risk exists to any personnel when operating the equipment in the normal manner,

following the recommended operating procedures.

All equipment maintenance and servicing procedures involve internal access and

should be carried out only by trained personnel.

BATTERIES

Battery manufacturers supply details of the necessary precautions to be observed

when working on, or in the vicinity of a large bank of battery cells. These

precautions should be followed implicitly at all times.

Particular attention should be paid to the recommendations concerning local

environmental conditions and the provision of protective clothing, first-aid and fire

fighting facilities

TEST EQUIPMENT

When the battery is under charge, it is earth-referenced about its mid-point –e.g. if

the battery s being charged at 460V the battery extremities will be at +230V and –

230V with respect to neutral (earth). When using mains-powered test equipment

such as oscilloscopes in the UPS voltage area, always use a differential mode of

operation to disconnect the oscilloscope frame earth.

PERSONNEL

When working inside the UPS (trained personnel only) it is recommended that

protection be worn to prevent eye damage, should an electric ware be struck by

mishandling or severe electrical fault.

Some of the power components are very heavy. If their removal is necessary, ensure

that sufficient manpower is available; otherwise use adequate mechanical handling

equipment.

When working in the general area of the UPS where high voltages are present, a

second person should be standing-by to assist and summon help in case of accident.

(1+N Parallel UPS System)

Note: As the unit outputs are connected in parallel, the System checks that the inverter control circuits

are perfectly synchronised with one another and with the Bypass Mains in terms of both frequency and

phase and that they have the same output voltages. Current supplied to the load is automatically

divided among UPSs. A warning message appears while synchronisation is in progress.

The UPS equipment should be installed by a qualified engineer in

accordance with the information contained in this chapter and all

equipment not referred to this manual is shipped with the details its

own mechanical and electrical installation.

W ARNING - Ba tte ry Ha z a rd s

· Special care should be taken when working with the batteries

associated with this equipment. When connected together, the

battery terminal voltage will exceed 400V DC, and is potential

lethal.

· Eye protection should be worn to prevent injury from accidental

electrical arcs.

· Remove rings, watches and all metal objects.

· Only use tools with insulated handles.

· Wear rubber gloves.

· If a battery leaks electrolyte, or is otherwise physically damaged, it

must be replaced, stored in container resistant to sulfuric acid and

disposed of in accordance with local regulations.

· If electrolyte comes into contact with the skin, the affected area

should be washed immediately with water.

NO TE

The UPS System can be connected to an IT (isolated neutral) power

Before cabling-up the UPS, ensure that you are aware of the location

and operation of the external isolators that connect the UPS input/

bypass supply to the mains distribution panel.

Check that these supplies are electrically isolated, and post any

necessary warning signs to prevent their inadvertent operation.

Note: The Emergency Stop action within the UPS shuts down the rectifier, inverter and static bypass

and trips the battery circuit breaker. It does not however internally disconnect the input mains supply.

If required, this additional action can be facilitated by feeding the UPS input via a circuit breaker

which can be tripped by a second contact of the Emergency Stop switch.

Note: Terminals 11 and 12 of the Auxiliary Terminal Block (X4) are connected to a normally closed

contact of the UPS Display Panel Emergency Stop button and go open circuit when the button is

pressed. This output can be used as part of a wider Emergency Stop system to initiate an external

action (such as tripping an external supply breaker)

General notes

Note1: All the user controls and indicators mentioned in these procedures are identified in chapter 1.

Some of diagrams are repeated here to assist in understanding the procedures.

Note2: The audible alarm may annunciate at various points in these procedures. It can be cancelled

at any time by pressing the ‘Alarm Reset’ push-button.

Note3: The Hipulse UPS System incorporates an optional automatic boost charge facility which can

be used in systems containing conventional flooded lead-acid batteries. If this type of battery

is used in your installation you may notice that the battery charger voltage may be greater

than its nominal (432V d.c. for 380V a.c., 446V d.c. for 400V a.c. and 459V d.c. for 415V a.c.

system) when the mains supply returns from a prolonged outage. This is the normal response

of the boost charge facility; the charger voltage should return to normal after a few hours.

C AUTIO N

A battery can present risk of electric shock or burn from high short

circuit currents.

When connected in a string the voltage could be 460 V d.c. this

voltage is potentially lethal always observe high voltage

precautions.

Only qualified personnel should install or service batteries.

Eye protection should be worked to prevent from accidental

electrical arcs.

Only use tools with insulated handles.

Wear rubber gloves and a rubber apron when handling batteries.

If a battery leaks electrolyte, or is otherwise physically damaged, it

should be placed in a container resistant to sulphuric acid and

NORMAL INTERPRETATION – ACTION

STATE

If this green led is OFF, it signifies a problem with the Bypass input a.c.

Check the following –

1. Bypass input power switch Q2 is closed.

2. Input Supply voltage is within 10% of nominal

3. Power supply fuses are OK – on the a.c. Power supply board will extinguish if either fuse is

ruptured.

If the above checks prove unsatisfactory then seek qualified assistance.

If this led is OFF, a problem exists in the Input power supply or in a part of the rectifier. An alarm message

is visible at the display.

Check the following –

1. The rectifier input isolator (Q1) is closed.

2. The input voltage is within the limits of normal operation.

3. The phase sequence of the mains input is correct.

4. Verify that condition leading to an emergency stop has not happened, in which case a Reset

must be carried out.

If these checks do not give a positive result, request qualified assistance.

If this yellow led is ON it signifies that the battery is not available. This could be due to the battery circuit

breaker being open or that the d.c. busbar voltage is below the figures stated in the item(2) specified

Sr. No. Display Message Alarm

Interpretation

EMERGENCY STOP

This alarm indicates that the UPS was shut down by means of the

local or remote (if fitted) Emergency Power Off push button (EPO)

which is normally due to operation action – investigate the cause

for pressing the button. If this button was not pressed then check

the continuity of the circuit to the Remote switch, Customer

connections, Auxiliary terminal block X4; pin 5 and 6; normally

closed.

INV. OFF

The INV. OFF alarm is active whenever the inverter is not producing

its correct output voltage, either because it has been switched OFF

or due to an internal fault, it will normally be accompanied by one

or more of the other inverter fault conditions.

INV: OVERVOLTAGE

Most of the inverter fault messages are self explanatory, however

the WAVEFORM ERR informs the operator that the output voltage

peak has flattened caused by an internal inverter problem and

therefore the output will be out of limits.

INV: UNDERVOLTAGE

OUTPUT: NO VOLTAGE

OUTPUT: WAVEFORM ERR

INV. OVERTEMPER.

Over temperature is sensed by a normally-closed thermostat (90°C

operating) fitted to each inverter heat sink. If an over temperature

condition arises, the audible alarm will accompany this message;

the inverter stops and load transfers to Bypass after 3 minutes.

OVERTEMP. SHUTDOWN

This message informs the operator that the inverter has been

switched OFF and that the load has been transferred ot Bypass due

to an Inverter over temperature.

OVERLOAD PRESENT

The inverter overload has an inverse load/ time characteristic – i.e.

it will accept 125% overload for 10 minutes and 150% overload for

60 seconds. If this characteristic is exceeded the load transfers to

the bypass supply, the inverter stops and the overload alarm

annunciates. The [OVERLOAD PRESENT] alarm will annunciate as

soon as the load exceeds 100% of the UPS rating, and the load will

transfer to Bypass some time later, depending on the degree of

OVERLOAD SHUTDOWN

OUTPUT SWITCH OPEN

BYPASS SWITCH OPEN

BATTERY C.B. OPEN

This message informs the operator that the load has been

transferred to bypass due to an inverter overload.

This is a status alarm. The output switch must be selected

‘CLOSED’ at all times except when operating on the Maintenance

bypass supply.

This is a status alarm. The bypass input switch must be closed all

the times.

10.

11.

12.

This is a status indication only. Note that if the UPS is operating

with the Battery circuit breaker open, and the mains power fails,

then the UPS output will also fail together with load power, since

the inverter has no battery backup.

BATTERY: FUSE FAIL

BATTERY: TEST FAILED

This problem should be rectified as soon as possible. If the mains

power fails then the UPS output will also fail together with load

power, since there is no battery backup.

The system has carried out a test of the battery. If this alarm is not

accompanied by a [BATTERY C.B. OPEN] or [BATTERY: FUSE FAIL]

message then a full check of the Battery bank is required.

13.

DC BUS: UNDERVOLTAGE

When the inverter is operating on the battery this message is

displayed on the condition when battery voltage has fallen below a

preset value. If the input a.c. power cannot be restored, you should

shut down your loads.

BATTERY: E.O.D.

RECT. OFF

The RECT. OFF alarm is active whenever the battery charger

(rectifier) is not producing its correct output voltage. This can be

caused by an operator selection to OFF, an Input supply failure, an

open rectifier a.c. input power switch or an internal fault which may

be accompanied by one of the fault conditions.

RECT. SWITCH OPEN

RECT. CURRENT LIMIT

BATTERY: FUSE FAIL

DC BUS: FAST OVERVOL

Most of the rectifier fault messages are self explanatory however,

the DC BUS: FAST OVERVOLTAGE message informs the operator

acceptable range. Do not switch OFF the inverter while this

indication is active or the load will lose its power.

BYP. OVERVOLTAGE

BYP. UNDERVOLTAGE

BYP. FREQUENCY ERROR

BYP. SCR FAILURE

One or more of the static switch SCR’s has developed a fault. The

bypass would not support the load in the event of a UPS failure,

immediate action is required. Seek qualified assistance.

BYP. PHASE ROT. ERROR

MANUAL BYPASS CLOSED

This message informs the operator that the input power lines have

been cross-connected and the phases sequence is incorrect.

This is a status warning that the load is being powered through the

maintenance bypass line and is unprotected from mains supply

aberrations.

21.

INV. UNSYNCHRONIZED

This warns that the inverter is not synchronized with the bypass

supply, which is normally due to a problem with the bypass supply

being outside an acceptable frequency window. Do not switch OFF

the inverter when this alarm is active or the load will experience a

200 millisecond power break.
