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 voltages 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 is being charged
at 460V the battery extremities will be at +230V and -230V with respect to neutral (earth). When using mains­powered test equipment such as oscilloscopes in the UPS high voltage area, always use a differential mode of
operation to avoid the need 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 electrical arc 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. Chapter 1 - General Description

1.1 Introduction

The 7200 Series uninterruptible power supply (UPS) system is connected between a critical load, such
as a computer, and its three phase mains power supply. Being designed to furnish a well regulated 3
phase output power supply under all rated load and input supply conditions, the system offers the user
the following advantages:

Increased power quality:

The UPS has its own internal voltage and frequency regulators which ensure that its output is
maintained within close tolerances independent of voltage and frequency variations on the mains power
lines.

Increased noise rejection:

By rectifying the input a.c. power to d.c. power, and then converting it back to a.c., any electrical noise
present on the input mains supply line is effectively isolated from the UPS output, therefore the critical
load sees only clean power.

Power blackout protection:

If the mains power fails, the UPS continues to power the critical load from its battery source, leaving
the load immune from power disturbances.

1.2 Design Concept

1.2.1 7200 Module Design

This section describes an individual module's operating principles. The UPS basically operates as an
a.c.-d.c.-a.c. converter (see figure 1-1). The first conversion stage (from a.c. to d.c.) uses a 3 phase,
fully-controlled SCR bridge rectifier to convert the incoming mains supply into a regulated d.c. bus­bar.

The d.c. bus-bar produced by the rectifier provides both battery charging power - which uses a
temperature compensated battery charging system, to prolong battery life - and power to the inverter
section – which utilizes the latest IGBT switching pulse width modulation ( PWM ) design - and
provides the second conversion phase, i.e. reconverting the d.c. bus-bar voltage back into an a.c.
voltage waveform.

During normal operation both the rectifier and inverter sections are active and provide regulated
load power whilst simultaneously float charging the battery. In the event of a mains power failure,
the rectifier becomes inoperative and the inverter is powered solely from the battery. Critical load
power is maintained under these conditions until the battery is fully discharged, whereupon the UPS
shuts down. The end of battery discharge is assumed when the battery voltage falls below a preset
value (i.e. 330V d.c. for a 400V a.c. system).
The period for which the load can be maintained following a mains power failure is known as the
system's ‘Autonomy Time' and is dependent upon both the battery A/Hr capacity and the applied
percentage load.

1.2.2 Bypass supplies

The circuit block annotated ‘Static Switch' in figure 1-2 contains an electronically controlled switching
circuit which enables the critical load to be connected either to the inverter output or to a bypass power
source via the `static bypass line'. Normally, the load is connected to the inverter via a contactor K1 (

controlled by the static switch circuits ); but in the event of a UPS overload, or inverter failure, it is
automatically transferred to the static bypass line.

To provide a clean ( no-break ) load transfer between the inverter output and static bypass line, the
static switch activates connecting the load to the bypass supplies followed by the K1 contactor opening.
When switching from the bypass supplies back to the inverter the K1 contactor closes first followed by
the static switch turning off. To achieve this the inverter output and bypass supply must be fully
synchronized during normal operating conditions. This is achieved through the inverter control
electronics which make the inverter frequency track that of the static bypass supply provided that the
bypass remains within an acceptable frequency window. The synchronizing window is pre-selected to
2% of nominal frequency, giving an acceptable frequency window ±1 Hz.

An [INV: UNSYNCHRONIZED] warning message is displayed on the operator control panel when
the inverter and bypass supplies are not synchronized; a second, manually controlled, `maintenance
bypass' supply is also incorporated into the UPS design. Its purpose is to enable the critical load to be
powered from the mains ( bypass ) supply while the UPS is shut down for maintenance or
troubleshooting.

Note: The load is unprotected against mains power supply aberrations or failure when it is
connected to either the static bypass or maintenance bypass supply.

1.2.3 UPS Power Switch Configuration

The power switch locations in the various 7200 models are shown in figure 1-3 figure 1-2 illustrates the
7200 series UPS module in what is known as the “Split Bypass” configuration. In the “Split Bypass”
configuration the static bypass line is connected by a separate power switch to a dedicated `bypass'
power source which also feeds the maintenance bypass line. Where a separate power source is not
available the Bypass ( Q2 ) and Rectifier input supply connections would be linked together.

With the exception of the maintenance bypass isolator, all the isolators shown must be closed during
normal UPS operation.

1.2.4 Battery circuit breaker

The battery is connected to the d.c. Busbar through a circuit breaker fitted inside the battery cabinet –or
located adjacent to the batteries where a battery cabinet is not used. This circuit breaker is closed
manually, but it contains an undervoltage release coil which enables it to be tripped from the UPS
control electronics following certain detected faults. It also has a magnetic trip facility for overload
protection.

1.2.5 Battery Cabinet

The batteries associated with the UPS are generally housed in a purpose-built cabinet located
along-side the main UPS equipment.

It is possible to install batteries of various types and capacity in the cabinet to obtain the required
autonomy characteristics.

The battery cabinet can be purchased in one of the following forms:

1. Complete installation comprising the battery cabinet, batteries and circuit breaker.

2. Battery cabinet and circuit breaker only –with no batteries.

3. Battery cabinet only –with no batteries or circuit breaker.

1.2.6 Battery circuit breaker box

As an alternative to the battery cabinet, a battery circuit breaker can be provided in a custom built box.
This Battery Circuit Breaker Box is designed to be wall or rack mounted and is connected between the
UPS and Battery.

1.2.7 Battery temperature compensation

For systems with batteries installed in non-optimized temperature conditions, the 7200 UPS offers a
battery temperature compensation circuit. As the temperature inside the battery cabinet/area rises the
d.c. bus bar voltage reduces in order to sustain the battery at its optimum charge voltage. This will
assist in prolonging the life of the battery.

The operator control and display panel can be divided into two functional sections; `LED indications'
and ` control and display'. As can be seen the upper section consists of LEDs which indicate the
operational and alarm status of the system by turning ON or OFF or by flashing ON/OFF. This section
can be further split into five separate areas as identified in figure 1-4.

The lower section of the operator control and display panel consists of a LCD ( Liquid Crystal Display
) and its associated switches.

1.3.1 LED indications

The control and display panel LED indications are illustrated in figure 1-5 and described in the
following text:

1. Bypass a.c. input supply present:

This led illuminates when the bypass a.c. input power switch is closed and the input supply is
within of set value nominal voltage ( default ±10% ).

2. Load on inverter:
This led illuminates when the output power switch is closed and the load is connected to the

inverter via the K1 contactor.

3. Load on bypass:
This led illuminates when the output power switch is closed and the load is connected to the

bypass a.c. supply via the static switch.

4. Battery Status:
This LED illuminates when the battery is discharging and flashes when the battery circuit

breaker is open.

5. 5 LED bargraph indicating % load:
These LED's illuminate progressively from the left to indicate the applied load as a percentage

of the maximum current load, increasing in 20% steps to 100% of full load when all five LEDs
are illuminated. The applied load reading is taken from the phase supplying the highest load.

6. 5 LED bargraph indicating % battery charge state or battery time remaining:
These LED's illuminate progressively from the left to indicate the state of charge of the battery

as a percentage of full charge, increasing in 20% steps to 100% when all five LEDs are
illuminated.

When the mains a.c. input supply fails and the UPS is operating on the battery, this bargraph

changes to give the battery time remaining. With a fully charged battery all five LEDs will
illuminate showing ten minutes or more autonomy, as time elapses the LEDs will extinguish in
steps starting from the right hand side.

7. Overload indication:
This amber LED is situated at the end of the % load bargraph and illuminates to indicate that

the applied load has exceeded 100%. This indication will be accompanied by audible and visual
LCD warnings.

8. Low Battery:
This amber LED is situated at the end of the % battery charge bargraph and illuminates when

operating on battery to indicate that the battery voltage is low at 1.8 volts per cell and that the
UPS will shortly shut down.

9. Alarm warning indication/alarm silence switch:
This red LED will flash whenever the UPS detects certain fault conditions and will normally be

accompanied by an audible warning. Pressing the button will silence the audible warning but
will not cancel the visual indication if the fault condition is still present.

Switch - Emergency Power Off (EPO):

The optional EPO switch is located remote to the UPS cabinet in a position agreed with the user. When
the EPO switch is pressed it disables the static switch block entirely (so removing load power). It also
disables the rectifier and inverter, and trips the battery circuit breaker. Under normal circumstances it
does not remove UPS input power since this is applied through a manually controlled external isolator;
however, if the UPS input supply is connected via a circuit breaker having an electrical trip facility,

2. Chapter 2 - Operating Instructions

2.1 Introduction

The UPS can be considered to be in one of three operating conditions:

• Normal operation - All relevant power switches and circuit breakers closed, the load is

powered by the UPS.

• On Maintenance Bypass - UPS shut down but the load connected to the unprotected mains via

the Maintenance Bypass Supply line.

• Shutdown - All power switches and circuit breakers open - no load power.

This chapter contains instructions which enable you to switch between the three above conditions, to
carry out a RESET after a fault transfer and how to switch OFF the inverter.

2.1.1 General notes

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

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

Note 2: The audible alarm may annunciate at various points in these procedures. It can be canceled
at any time by pressing the `Alarm Reset' push-button.

Note 3: The 7200 series UPS 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 a 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.

IMPORTANT

The Maintenance Bypass Power switch may be operated at any time when the UPS is powered down to connect the
load to the maintenance bypass supply if required.
The load equipment is not protected from normal supply aberrations when operating in the maintenance bypass
mode.

2.6 Procedure for carrying out a RESET after a recognised controlled transfer
to bypass or EPO action.

When the necessary action to correct the problem has been taken, this procedure should be followed to
restore the UPS back to its normal operating condition following, a controlled transfer to bypass or
when the Remote Emergency Power Off switch has been activated.

A recognized controlled transfer to bypass is activated by the following problems: Inverter
Overtemperature, Cut-off Overload, Battery Over voltage, when configured for a manual return from
bypass operation ( only for system test ).

1. Gain access to the UPS logic board - Open the UPS right hand door ( see figure 2-2 ).

2. Press the RESET push switch, labeled S1 on the UPS Logic board (part number 4550004E.
This operation can be easily done trough the hole on the screening panel using, for instance, a

plastic pencil or similar.

Operation of this push button resets the logic circuitry to enable the rectifier, inverter and static

switch to operate normally.

Note: When the remote EPO switch has been activated it is necessary to manually close the

battery circuit breaker.

When the EPO system incorporates a trip facility of the external input a.c. power supply circuit

breaker, the RESET switch would have no affect on it. First close the external input a.c. supply
circuit breaker, the UPS can be started in the normal manner, as the logic circuits will
automatically reset on return of the power supplies.

3. On completion close the UPS doors.

3. Chapter 3 - Installation Procedure

3.1 Introduction

WARNING

Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer.

WARNING

The UPS equipment should be installed by a qualified engineer in accordance with the information contained in
this chapter and the drawing package shipped inside the UPS cabinet

WARNING

Battery hazards

Special care should be taken when working with the batteries associated with this equipment. When connected
together, the battery terminal voltage will exceed 400 Vdc and is potentially 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 a 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

This chapter contains information regarding the positioning and cabling of the UPS equipment and
batteries.

Because every site has its peculiarities, it is not the aim of this chapter to provide
step-by-step installation instructions, but to act as a guide as to the general
procedures and practices that should be observed by the installing engineer.

Issue 6
(03/98)

3.1.1 Equipment positioning and environmental considerations

The UPS cabinets are fitted with castors on the base to allow ease of movement and positioning. When
the equipment has been finally positioned ensure the adjustable feet are set so that the UPS will remain
stationary and stable (see figure 3-2).

The UPS can be lifted using either a fork lift, or a cradle. Take care when using either method not to
damage the UPS castors or jacking feet located on the bottom of the unit.

WARNING

Ensure that the UPS weight is within the designated S.W.L. of any handling equipment. See the UPS specification
for weight details.

Do not move battery cabinets with the batteries fitted.

The UPS module should be located in a cool, dry, clean-air environment with adequate ventilation to
keep the ambient temperature within the specified operating range. Where ventilation is poor and
ambient temperature is high, a system of extractor fans should be installed to aid cooling-air flow, and a
suitable air filtration system used where the UPS is to operate in a dirty environment.

Cables

All control cables should be screened and run separate from the power cables, in metal conduits or
metal ducts which are electrically bonded to the metalwork of the cabinets to which they are connected.

Cooling air flow

All the models in the 7200 range are force-cooled with the aid of internal fans. Cooling air enters the
module through ventilation grills located at the bottom of the front doors and is exhausted through the
fan grills located on the rear panel; you must therefore allow for a minimum gap of 250 mm behind the
unit to allow adequate air flow (see figure 3-1).

Clearances

Clearance around the front of the equipment should be sufficient to enable free passage of personnel
with the doors fully opened.

3.1.2 Raised floor installation

If the equipment is to be located on a raised floor it should be mounted on a pedestal suitably designed
to accept the equipment point loading. The installation diagrams accompanying the system identify the
location and equipment through which the cabinet can be secured to the floor.

3.1.3 Battery Location

Temperature is a major factor in determining the battery life and capacity. Battery manufacturers quote
figures for an operating temperature of 20°C. Operating above this temperature will reduce the battery
life, operation below this temperature will reduce the battery capacity. On a normal installation the
battery temperature is maintained between 15°C and 25°C. Batteries should be mounted in an
environment where the temperature is consistent and even over the whole battery. Keep batteries away
from main heat sources or main air inlets etc.

Pedestals are required for the battery cabinets when they are located on raised floors, in the same way
as for the UPS cabinets.

Edition).

Notes:

1. The neutral conductor should be sized for 1,5 times the output/bypass phase current.

2. The earth conductor should be sized at 2 times the output/bypass conductor (this is dependent

on the fault rating, cable lengths, type of protection etc.).

3. Table 4D1A applies to single core PVC-insulated, non armored cable in a ambient temperature

of 30°C, according to fixing method 1, samples shown in figure 3-3.

4. These recommendations are for guideline purposes only and may be superseded by local

regulations and codes of practice.

3.3.3 Cable connections

The input mains/bypass cables, UPS output cables and battery cables ( all require lug type terminations
) are connected to busbars situated between the power isolator switches - as shown in figure 3-5. A
terminal block X3 is used for connecting the control cables to the battery circuit breaker and the
external emergency stop facility, these are female spade type connections ( Fast-on 6,3x0,8 ).

3.3.4 Safety earth

The safety earth bus-bar is located near the input and output power supply connections as shown in the
following diagram. The safety earth cable must be connected to the earth bus-bar and bonded to each
cabinet in the system.

All cabinets and cable trunking should be earthed in accordance with local regulations.

WARNING

FAILURE TO FOLLOW ADEQUATE EARTHING PROCEDURES CAN RESULT IN ELECTRIC SHOCK
HAZARD TO PERSONNEL, OR THE RISK OF FIRE, SHOULD AN EARTH FAULT OCCUR.

3.3.5 Protective devices

Bypass input of UPS is not self-protected against overloads or shorts circuits: it’s necessary to install
in distribution panel a circuit breaker or fuses to protect bypass line.

Rectifier input: it’s the same, in case of separate rectifier input, it’s necessary to install in distribution
panel another circuit breaker or fuses to protect input wires.

The UPS is fitted with RFI suppression filters, earth leakage current exceeds 3.5 mA and is less than
500 mA.
Earth leakage current of loads will add when UPS is operating from bypass supply.
Residual Current Circuit Breakers ( RCCBs ) must be selected insensitive to DC unidirectional pulses
( class A ) and transient current pulses.
They are identified by the symbols

Output of UPS: an insulator switch may be inserted in distribution panel for maintenance purpose; be
sure don’t use a protective device for the whole output power of UPS, in particular don’t use RCCB.
Protective devices may be used for distribution lines to loads, be sure that they are selective with
protecting devices in input of UPS.

(03/98)

4.1 AS400 Alarm Interface Board (4590055 P)

The Alarm Interface board is fitted in the right hand side of the unit, on the front lower face ( see
figure 4-2 ) near the auxiliary terminal block ( X3 ) and is connected to the UPS control electronics (
UPS Logic board ) by a ribbon cable (W10), which is normally stowed in the cable loom when not in
use. The board has several functions as described below.

4.1.1 Remote control inputs

The Interface Board has facilities to accept three remote control inputs, as shown in figure 4-1. One
remote input allows the inverter to be shut down ( transferring the load to the bypass supply ). The
second remote input can be configured to reduce the input current limit, reduce battery current limit,
inhibit inverter synchronization. This feature is most often used when the input mains supply fails, and
the UPS is powered from a standby generator, which may not be large enough to maintain power
supplies within the normal parameters. The third remote input is not used at this time (spare).

The external control signals ( 12V d.c. or a.c. ) should be connected to terminal block X5 as shown in
figure 4-1. The voltage applied to these terminals must be generated by an external power source and
not taken from the UPS internal low voltage supplies.

4.1.2 AS400 Interface

The AS400 Interface connects the five most operationally critical UPS alarms to an IBM AS400
computer, which is designed to monitor such alarms and respond to their appearance.

The alarms in question are:

• Mains failure

• Load on UPS

• Low battery and/or battery circuit breaker open

• Load on mains (bypass)

• Load on maintenance bypass

Connection to the AS400 is provided on the Interface Board via a terminal block X3. These alarm
signals are provided by volt-free relay contacts, Maximum contact rating is 50 Vcc @ 1 Amp.

4.1.3 Alarm outputs

In addition to the AS400 alarm outputs the Interface Board also contains a number of relays whose
contacts provide a set of volt-free alarm outputs that are connected to terminal block X4 as shown in
figure 4-1. These outputs can be used to drive an external alarms monitoring device. Maximum contact
rating on M1 terminals = 50 Vcc @ 1 Amp.

Note: When using the above contacts for remote alarm annunciation, the power supply for the
remote indicators must be provided from an external power source. Under no circumstances
should the UPS internal low voltage supplies be used for this purpose.

4.1.4 X2 Extension

The X2 connection on the board is provided to interface the UPS systems with the remote alarms board
part number 4590056Q which contains additional alarms.

4.2 Remote Alarms Interface Board (4590056 Q)

4.2.1 Alarm outputs

The Remote Alarms Interface board is fitted in the right hand side of the unit as shown in figure 4-2
and is connected (piggy back style) directly via connector X1 onto the Interface Board connector X2.
This board therefore can only be used in conjunction with the Interface Board (4590055P).

The Remote Alarms Interface board contains a number of relays driven by alarm signals generated
within the UPS, whose contacts provide a set of volt-free alarm outputs that are connected to terminal
blocks X2 and X3 as shown in figure 4-3. These outputs can be used to drive an external alarms

monitoring device.

Maximum contact rating on M1 terminals
50 Vcc @ 1 Amp.

Note: When using the above contacts for remote alarm
annunciation, the power supply for the remote
indicators must be provided from an external power
source. Under no circumstances should the UPS
internal low voltage supplies be used for this purpose.

4.3 Additional 3 x AS400 Interface (4590057 R)

This board is connected (piggy back style) directly via connector X1 onto the Interface Board
connector X2 of 4590055 P, in the same place of 4590056 Q. This board can only be used in
conjunction with the Interface Board (4590055 P).

It is not possible to fit both 4590056 Q and 4590057 R boards.

The Additional 3 x AS400 Interface connects the UPS up to three IBM AS400 computers, all they
are totally insulated (ground and signals).
Alarms logic and contact rating are the same as the section AS400 of 4590055 P board: this circuit
is repeated three times on 4590057 R, so it is possible to connect up to 4 AS400 to the UPS.

4.4 Remote Alarm Monitor (4305001 Z)

When used in conjunction with the Interface board described previously, the Remote Alarm Monitor
enables the auxiliary alarm signals to be displayed at a remote station up to 100 meters from the main
equipment.

The RAM, which can be mounted either horizontally or vertically, contains a mains-driven power
supply for alarm LED annunciation and displays the following warnings:

Panel Colour Normal state Interpretation

INVERTER ON green ON Normal operating condition indicating that the load is being supplied by

the inverter. This is not an `alarm' indicator.
UTILITY FAILURE red OFF When lit, it indicates that the input bypass is out of tolerance or missing.
BATTERY LOW red OFF When lit, it indicates that the battery voltage is below minimum or that

the battery circuit breaker is open.
BYPASS ON red OFF When lit, it indicates that the load is being fed from the bypass supply,

possibly due to a UPS failure.
BYPASS
MAINTENANCE

red OFF When lit, it indicates that the UPS has been selected to operate on the

maintenance bypass and the load is unprotected
ALARM red OFF This is a `common alarm' and is lit when any of the red leds described

above are lit.

Table 4-A

An audible warning accompanies any of the above alarm conditions. This is, however, subject to a
short time delay when activated in conjunction with the `Utility Failure' and `Bypass ON' alarms, to
prevent the warning being activated by transient conditions. Pressing the `reset' push-button cancels the
audible warning but the alarm indications remain until the condition is rectified.

4.4.1 Connections

Power supply

The RAM contains a single phase 220-240 V a.c. mains-driven power supply. Power is applied
through a standard three-pin mains connector located in the RAM back panel (plug provided) use
3-core 0.5 mm2 cable (minimum). The supply is rated at approximately 4 Watts and fused at 1A.
It is advised that the power supply is taken from the UPS output, otherwise in the event of a mains
failure the RAM may be inoperative.

Alarm connections

A 9 pin D-type connector with solder points is provided with the RAM. This connector fits into the 9
pin socket on the back of the RAM and should be cabled to the Interface Board (4590055 P), fitted to
the UPS, using 9 core, 0.22 mm. (minimum) shielded cable as shown. The maximum recommended
distance is 100 meters.

4.5 Battery cabinets

WARNING

Only qualified personnel should install or service batteries.
A battery can present a risk of electric shock or burns from high short circuit currents.
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 should be replaced and stored in a container
resistant to sulphuric acid and disposed of in accordance with local regulations.
If electrolyte comes into contact with the skin the affected area should be washed immediately.
Batteries MUST be disposed of in accordance with local environmental laws.

Three types of cabinets are available for 38 Ah, 50 Ah and 85 Ah batteries. The cabinets have the same
height, width and design as the UPS and can be installed on either side of the UPS.

The cabinets are equipped with an automatic circuit-breaker, with magnetic overcurrent protection and
undervoltage tripping, controlled from a special board (part no. 4520067T) mounted inside the battery
cabinet.

This circuit-breaker has the following features:

• cabinet insulated for safety

• short-circuit protection

• circuit-breaker automatic opening when the Inverter is locked out due to battery undervoltage, thus

avoiding damaging discharges to the battery

• circuit-breaker remote breaking action using the emergency stop button, if installed

• protection against operating errors ( closing the circuit-breaker with the rectifier disabled )

• protection against battery cabinet and UPS connection errors ( polarity reversal +/- )

The cabinets have the following part numbers:

• part no. 5320031 P for 12V/38 Ah batteries with 100 A circuit-breaker

• part no. 5320032 Q for 12V/50 Ah batteries with 100 A circuit-breaker

• part no. 5320038 W for 12V/85 Ah batteries with 160 A circuit-breaker

The cabinets can be supplied with batteries already installed or empty.

Cabinets with batteries already installed.

These cabinets are shipped with open connections between the shelves. Since it may be necessary to
remove the rear panel, these connections must be made prior to positioning. These are indicated in
figures 4-7, 4-9, 4-11 and 4-12.

Note The continuous voltage value, and therefore the number of battery blocks, depends on the value of

the mains input and output voltages (see Electrical data - Chapter 8). Figures 4-7, 4-9, 4-11 and
4-12 indicate the maximum equipment layout (34 single 12 V blocks for 415V input/output
voltage); they also indicate the single blocks positions which are not installed for mains voltage
of 400V (33 single blocks ) or 380V (32 single blocks).

4.6 Battery circuit breaker boxes

The boxes contain a battery isolating circuit-breaker and the Control board part no. 4520067 T as also
mounted in the Battery Cabinets.

The circuit-breaker boxes are designed for wall mounting, when the circuit-breaker is not installed in
special cabinets, and must be located near the battery.

An earth connection must be provided.

Two boxes are available depending on the UPS power rating:

• part no. 4641027 B with 100 A Circuit-breaker for 30 - 40 kVA UPS.

• part no. 4641028 C with 160 A Circuit-breaker for 60 kVA UPS.

The circuit-breaker includes magnetic overcurrent protection and an undervoltage tripping release. It
offers the following features:

• battery isolation for safety

• short-circuit protection

• circuit-breaker automatic opening when the Inverter is locked out due to battery

undervoltage, thus avoiding damaging discharges to the battery

• circuit-breaker remote breaking action using the emergency stop button, if installed

• protection against operating errors (closing the circuit-breaker with the Rectifier disabled )

• protection against Battery cabinet and UPS connection errors ( polarity reversal +/-)

• Figure 4-13 indicates the connections between the UPS and the Battery circuit-breaker Box.

4.6.1 Temperature Sensor Board (4532029 V)

With this feature fitted and enable the nominal float voltage supplied to the battery is adjusted so as
to be inversely proportional to the ambient battery cabinet/room temperature (as monotored by a
remote temperature sensor). This prevents the battery being over charged at high ambient
temperatures.

4.7 Input Harmonic filter

4.7.1 Introduction

An optional input harmonic filter can be added to the 7200 series UPS to improve the UPS input power
factor and reduce the amount of electrical noise reflected into the input three phase supply.

The filter components are contained within the UPS cabinet therefore extra cooling is required ( see
figure 4-15 ). The filters are matched to the UPS capacity, resulting in different part numbers for each
system as follows:

30 kVA filter 4641015 P
40 kVA filter 4641016 Q
60 kVA filter 4641017 R

4.7.2 Specification

Input voltage 380-400-415, three phase
Input voltage tolerance ±10%
Nominal frequency 50 Hz
Input frequency tolerance ± 5%
UPS input current distortion 10% max.
UPS input power factor >0.9

4.7.3 Notes on connection

This option is normally factory fitted with the harmonic filter becoming an integral part of the UPS as
shown in the block diagram figure 4-14 and the component location diagram figure 4-15. Therefore,
connection of the input power supplies does not change from that given in chapter 3.

Note: The input Neutral connection must always be connected to the bypass input `N3' on the UPS.

Issue 6

(03/98)

5. Chapter 5 - Maintenance

5.1 Introduction

This chapter contains the procedures necessary to effect general maintenance of the UPS module and
battery. Certain procedures entail gaining internal access to the UPS, and should only be undertaken by
a competent engineer who is familiar with the operation and layout of the equipment and understands
the areas of potential hazard. If you have any doubts concerning safety or the method of carrying out
any procedure then contact an approved service agent for assistance or advice. If the locally approved
agent is not known to you, then you should contact the Customer Services & Support department at the
address shown at the front of this manual.

The manufacturer offers customer training, at a nominal fee, if required. Such training can range from a
one-day operator course to in-depth training on maintenance and troubleshooting lasting several days,
and can be carried out at the manufacturer's plant or at the customer premises.

5.2 Safety Precautions

When working on the UPS remember that the equipment contains live voltages at ALL TIMES unless
it is externally isolated from the mains supply, bypass supply and batteries. It is essential that the safety
and precautionary notes contained throughout this manual are read and FULLY UNDERSTOOD
before touching any UPS internal component part.

5.3 Scheduled Maintenance

The UPS utilizes solid-state components which are not subject to wear, with the only moving parts
being the cooling fans. Scheduled maintenance requirements, beyond ensuring that the environmental
conditions remain suitably cool and clean, are therefore minimal. However, a well documented
periodic program of inspection and preventive maintenance, as suggested below, will help to ensure
optimum equipment performance and may serve to detect certain minor malfunctions prior to them
developing into a major fault. To monitor the various parameters follow the instructions shown in
paragraph 5.4.

5.3.1 Daily checks

Carry out a daily walk-by inspection of the UPS, checking the following points:

1. Carry out a spot check of the operator control panel; ensuring that all mimic LED indications

are normal, all metered parameters are normal and no warning or alarm messages are present on
the display panel.

2. Check for obvious signs of overheating.

3. Listen for any noticeable change in audible noise.

4. Ensure that the ventilation grills around the UPS are unobstructed.

5. If possible, log the results of the inspection, noting any discrepancies from the norm.

Chapter 5 - Mantenance 7200 Series UPS User Manual
Scheduled Maintenance Single Module and 1+1 Parallel System

document in response to "powersure ups"

Page 5-2

Issue 6
(03/98)

5.3.2 Weekly checks

Carry out the following checks from the mimic panel and log the results:

1. Measure and record the battery charge voltage.

2. Measure and record the battery charge current.

3. Measure and record the UPS output voltage on all three phases.

4. Measure and record the UPS output line currents. If these are significantly different from the

values previously logged then, if possible, record the size, type and location of any additional
load connected to the UPS supply since the previous inspection. This type of information could
prove useful to the troubleshooting engineer should a problem occur.

If any of the above indications differ greatly from the previously logged values for no apparent reason
then you should contact the Customer Service & Support Department at the address given at the front
of this manual for advice.

5.3.3 Annual Service

The equipment should be thoroughly cleaned and the following checks carried out annually. This
entails working inside the equipment in regions containing hazardous voltages.

A manufacturer-trained engineer is fully aware of the hazards concerned and will carry out this
procedure with the load connected to the maintenance bypass supply; however if the customer decides
to carry out this service procedure himself it is imperative that the UPS be totally shut down and
isolated from the input mains and bypass supplies and batteries using the procedure given below. We
therefore strongly recommend that the annual service is carried out by trained personnel.

1. Carry out the weekly checks detailed above.

2. Shut down the UPS following the recommended operating procedure.

3. Isolate the UPS input mains supply externally (also the bypass supply if a split bypass system

is in use) and isolate the battery.

4. Ensure that the UPS is totally powered down by checking for voltage at the rectifier input

connections (U1, V1 & W1), the battery connection terminals, the output connections (U2,
V2 & W2) and the bypass input connections (U3, V3 & W3).

5. Gain full access to the UPS interior by opening its internal hinged safety panel.

6. Carry out a thorough examination of the UPS power components and sub-assemblies, paying

particular attention to the following:-

Electrolytic capacitors - Check for signs of leakage, buckling etc.

Magnetic components - Check for signs of overheating, security of fixture and signs of

delamination.

Cables and connections - Check cables for chaffing, fraying or signs of overheating. Check

that all printed circuit board connectors are secure.

Printed circuit boards - check the cleanliness and integrity of the circuit boards and replace if

any signs of deterioration are found.

7. Thoroughly clean inside the equipment enclosure using a vacuum cleaner and low pressure air

to remove any foreign debris.

7200 Series UPS User Manual Chapter 5 - Maintenance
Single Module and 1+1 Parallel System Scheduled Maintenance

document in response to "powersure ups"

Page 5-3

Issue 6

(03/98)

8. Reconnect the UPS input mains power.

9. Start the UPS and transfer the load to the inverter following the appropriate operating

procedure.

10. If possible, check the battery autonomy time by opening the rectifier input power switch ( Q1

) with the UPS on-load. Close the rectifier input power switch ( Q1 ) immediately the dc
busbar voltage falls within 5 volts of the battery end of discharge voltage. ( note the end of
battery discharge is assumed when the battery voltage falls to 320V d.c. for a 380V a.c.
system; 340V d.c. for a 400V a.c. system; 340V d.c. for a 415V a.c. system ). At this voltage
the battery circuit breaker will trip and the load will transfer to bypass. Ensure that the
available battery autonomy time meets the installation specifications.

5.3.4 Extended service

We recommend that ALL the input/output power cables and their connections are checked
periodically. As this requires the UPS to be completely shut down such a check should be carried out
on an `opportunity' basis but at an interval not exceeding 2 years.

5.3.5 Battery maintenance

The batteries used with the UPS are generally sealed, valve-regulated type, and the only maintenance
requirement is to ensure that the cells are kept clean and dry. Maintenance procedures appropriate to
both valve-regulated and non-sealed batteries vary, and should be obtained from the battery
manufacturer.

6. Chapter 6 - Trouble shooting

6.1 Trouble shooting UPS Systems

The UPS contains complex electronic control circuits that require a firm understanding in order to
carry out comprehensive fault diagnosis and repair of the equipment. The following information aims
to provide a trained user with sufficient knowledge to understand the nature of a fault through the
correct interpretation of the accompanying alarms and indications, and to carry out any necessary first
aid repair action.

WARNING

Some of the instructions in the charts at the end of this chapter involve checking internal fuses. This should be
undertaken ( after the equipment has been shut down ) only by a trained electrician who is familiar with the layout
and operation of the equipment and fully conversant with the areas of potential hazard.

6.1.1 Operating parameters and limitations

Most UPS problems do not emerge as a gradual performance degradation; generally the UPS either
works correctly or it will shut down - and transfer the load to the bypass supply if applicable. However,
it is important to maintain a regular record of the UPS meter indications, as suggested in the
maintenance instructions, in order that any change in the system or load characteristics are readily
identified.

In general, the output voltage should be within 2% of nominal. If the UPS has not operated on battery
power within the previous ten hours the battery charge current should be typically less than 6A.

If any indication differs significantly from the typical figures given above the cause should be
investigated.

Information concerning prevailing load conditions can prove useful when discussing problems with
the service agent - for example, details of any particular load being started or shed at the time that the
fault occurred.

6.1.2 General Trouble shooting Procedure

Trouble shooting should be carried out methodically using the following guidelines:-

Fault Identification

When first summoned to the scene of a UPS fault, your immediate action should be to observe and
record the displayed messages, mimic indications and the position of the UPS power isolator switches.
This should be completed before you touch any switch.

Corrective Action

When all the indications have been noted, you should refer to the following fault interpretation charts
and carry out the actions detailed against any led whose status is abnormal. If you are unsure as to how
to undertake the actions detailed - or if several led indications are abnormal and you are unable to
distinguish between the likely cause and affects - then seek immediate assistance from an approved
service agent.

Chapter 6 - Trouble shooting 7200 Series UPS User Manual
Trouble shooting UPS system Single Module and 1+1 Parallel System

document in response to "powersure ups"

Page 6-2

Issue 6
(03/98)

Fault Reporting

Irrespective of whether fault rectification is successful or not, report the fault occurrence to the nearest
service agent who will then forward the details to the manufacturer. This type of customer feedback is
an important factor in maintaining high product reliability, and also provides important data concerning
the equipment field performance.

Caution

The following diagnostic charts are designed for 'first aid' trouble shooting only. If a problem cannot be resolved
by taking the actions given then fully trained assistance should be sought immediately.

Do not under any circumstances make internal circuit adjustments or interfere with the circuit boards in any other
way.

INTERPRETATION - ACTION

1 ON If this green led is OFF it signifies a problem with the bypass input a.c.

Check the following:
a) Bypass input power switch Q2 is closed.
b) Input supply voltage is within 10% of nominal.
c) Power supply fuses are OK - LS1, LS2 on the a.c. Power Supply board will extinguish if

either fuse is ruptured.

If the above checks prove unsatisfactory then seek qualified assistance.

2 ON If this green led is OFF it signifies that the inverter is not producing its correct output voltage.

Check the following:
a) If [OVERTEMPERATURE] or [OVERLOAD] alarm messages are active then (after allowing
the UPS to cool / checking that the load current on the bypass line is not excessive) press the reset
switch (S1) on the UPS Logic Board.
b) If the d.c. busbar is below 320V d.c. for 380 V a.c. system, 330V d.c. for 400 V a.c.. system

or 340 V d.c. for a 415 V a.c. system then do the checks as per `Rectifier Block'- input failure
items 15,16,17 & 18 in the following table

c) If the inverter works OK when mains is available but not when mains is unavailable then

check the battery power fuse F13.

If the above checks prove unsatisfactory then seek qualified assistance.

3 OFF If this yellow led is ON (flashing) then it signifies that the load has been transferred to the static

bypass supply. If this is an automatic change over it will be accompanied by a fault warning on the
display panel: take the appropriate actions for the display indication (see Display alarm message
table).

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

battery circuit breaker being open or that the d.c. busbar voltage is below the figures stated in (2)
above.
The battery circuit breaker will open automatically if the d.c. voltage falls below these levels.

Check the following:
a) Battery circuit breaker is closed.
b) DC busbar voltage — if not above 320V

then carry out checks as per 1 (mains failure) above. If the d.c. busbar voltage is greater than
320V but you are unable to close the battery circuit breaker then seek qualified assistance.

c) If the battery circuit breaker trips as soon as mains power is disconnected then check the

battery power fuse (F13).

5 N/A This is a bar graph indicating the % of the total load that is being applied to the system under

normal running conditions several of these LEDs would be ON.

6 N/A This is a bar graph indicating the battery charge state and would normally have four or five of the

LEDs ON. When the unit runs on battery, this bargraph changes to give an indication of the time
remaining on battery as 2 minutes per led.

7 OFF If this yellow led is ON it signifies that the applied load has exceeded the maximum. It will be

accompanied by all five load bargraph LEDs being ON (item 5), the Alarm warning indication
flashing RED(item 9) and an OVERLOAD message on the visual display. This will be accompanied
by an audible warning. Reduce the load immediately.

8 OFF If this yellow led is ON it signifies that the battery voltage is low and that the end of battery

discharge is near (normally two minutes). This will be accompanied by an audible warning

9 OFF This red LED will flash on and off and indicates that the UPS has detected a fault, it will be

accompanied by a message on the display panel, take the required actions for the display panel
message (see Display alarm message table). This will be accompanied by an audible warning.

OUTPUT: NO VOLTAGE
OUTPUT: WAVEFORM ERR

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.

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.

45INV.: OVERTEMPER.

OVERTEMP. SHUTDOWN

Over temperature is sensed by a normally-close thermostat ( 90o 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.

This message informs the operator that the inverter has been switched off and that the
load has been transferred to bypass due to an inverter over temperature.

67OVERLOAD PRESENT

OVERLOAD SHUTDOWN

The inverter overload has an inverse load/time characteristic – i.e. it will accept 125%
overload for 10 minutes and 150% for 60 seconds. If this characteristic is exceeded
then 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 present.

This message informs the operator that the load has transferred to bypass due to an
inverter overload.

8 OUTPUT SWITCH OPEN This is a status alarm. The output switch must be selected `CLOSED' at all times

except when operating on the maintenance bypass supply

9 BYPASS SWITCH OPEN This is a status alarm. The bypass input switch must be closed at all times.

10 BATTERY C.B. OPEN 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 back-up.

11 BATTERY: FUSE FAIL 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 the inverter has no battery
back-up.

12 BATTERY: TEST FAILED 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 when the

battery voltage has fallen below a preset value. If the input a.c. power cannot be
restored you should shut down your loads.

14 BATTERY: E.O.D. Battery discharge has continued beyond a preset value. The inverter will have shut

down, the system will attempt a transfer to bypass: if there is no bypass supply

7. Chapter 7 - 1+1 Parallel System

7.1 Generality

The system consist of two single UPS 7200 modules with the same power rating. Each UPS is equipped
with the optional parallel Kit (part no. 4645004A), and the outputs to the load are connected in
parallel.
The system can be configured on site as follows:

• redundant parallel

• power parallel (available with software revision V4.1 and subsequent revisions and High-Voltage

Interface board part no. 4590058S)

Redundant parallel

A system is defined a being in a redundant parallel configuration when the load power rating is less than
or equal to the rated power of are UPS module. In this case, only one UPS is needed to supply the load.
◊ Normal operation

Both the UPS units supply the load. They automatically share current and are synchronised with to
the mains. They remain synchronised to each other during a power outage and are synchronised
again with the mains when power is restored.

◊ Fault or manual inverter shutdown

The load continues to be supplied by the inverter of the second UPS.

◊ Overload

The system has a very high overload capacity, equal to the sum of the power ratings of the two UPS
units plus the relative overload (minimum three times the supplied load). If the power demanded by
the load temporarily exceeds this value, the load switches to the mains bypass through both UPS
modules.

◊ Maintenance

Maintenance can be performed on a UPS by opening the relative switches without using the
internal manual By-pass, since the second UPS can supply the load.

Power parallel

A system is defined a being in a power parallel configuration when the power requested by the load is
greater than the rated power of one UPS module. In this case, both UPS modules are needed to supply
the load.

◊ Normal operation

Similar to the redundant parallel configuration.

◊ Fault or manual Inverter shutdown

The load is switched to the mains bypass through the Static Switches of both UPS modules, even if
the power requested at that time by the load is less than the power rating of one UPS.

◊ Overload

The overload capacity is equal to 1.5 times the system power rating.

◊ Maintenance

To carry out maintenance operations, both UPS modules must be switched to manual bypass.

Battery configuration

The system is designed to operate with two different battery configurations:

◊ With separate batteries

Each UPS is connected to its own battery (see figure 7-1).
This is the most common configuration.

◊ With common battery

The two UPS units are connected to a single battery (see figure 7-2).
The option “Battery auxiliary distribution box” (see paragraph 7.4) is required for common battery.

(03/98)

7.2 Installation procedure (Separete batteries)

Installation procedure is basically the same as for single module, so
read and apply instructions of Chapter 3 - Installation Procedure of
this User Manual.
Differences are shown below.

7.2.1 Preliminary Checks

Be sure that the option parallel kit is present and connected for both
modules, that they are the same size and with the same SW and HW
release.

WARNING

Operation of fitting the parallel kits and setting of boards and UPS to

convert it from Single Module to 1+1 must be made by Liebert Service &

Support trained personnel.

This operation involves also setting of system with:

separate batteries or common battery, 1+1 redundant or full power

7.2.2 Power cables

Input Bypass and Rectifier, outputs of modules

As shown in fig. 7-1 and 7-2, to achieve maximum flexibility, is suggested to use separate isolators and
protections for each module: in this case rating of cables is the same as for single module.

As for single module, it’s suggested to use a power isolators at the output of each module: this power
isolators connected at the output of UPS is only for plant maintenance:

it must not be used for protection of UPS output or cabling

this protection is deemed to input bypass line breaker and current limit of inverter.

The cross section and lenght of the cables on the bypass line and on the output of the two UPS modules
should de equal, to ensure the balance of the currents when the load is supplied by the bypass mains.

7.2.3 Control cables

Parallel bus

Each module has its Parallel Board ( s. n. 4520075B ) connected with the other via two shielded 34­poles flat-cables.
The connection is redundant, disconnecting one cable lits a red LED on Parallel boards, disconnecting
both cables inverters are blocked ( this last function may be disabled during servicing of the system ).

Cables length is fit for connection of two modules side by side; cables enter in cabinets passing trough
the slot right in the base of cabinet ( see Fig. 3-2 ).

Emergency Power Off ( EPO )

It’s suggested to use an emergency power off push button with two separate and insulated ways, so it’s
possible to power off both modules at the same time.
A third insulated way may be used to trip input breakers of distribution panel if it’s needed to power off
also inputs of modules.
For EMI reasons cabling must be shielded and shield must be grounded at EPO side.

7.3 System start-up and shutdown procedures (Separate batteries)

These operations must be performed one at a time, progressing to the next step only after having
completed the previous step on both UPS modules.

7.3.1 System start-up

Follow the procedure for the single UPS by referring to paragraph 2.2.
For a system configured in the “redundant parallel” mode, the first of the two UPS modules available
will change its state from “load on bypass” to “load on inverter” (turning on and off the relative mimic
leds) and will inhibit the “load on bypass” message on the second module. When the second module
becomes available, it will enter the “load on inverter” state and this led on the mimic panel will turn on.
For a system configured in the “power parallel” mode, the two UPS modules will simultaneously
change from “load on bypass” to “load on inverter” when both will become active.

7.3.2 Switching the system to maintenance bypass from normal operation.

Follow the procedure for the single UPS by referring to paragraph 2.3.
For a system configured in the “redundant parallel” mode, the changeover from “load on inverter” to
“load on bypass” will occur only when the operation described in point 4 has been completed on both
UPS modules.

7.3.3 Switching the system ON from a maintenance power down condition.

Follow the procedure for the single UPS, referring to paragraph 2.4.

7.3.4 Switching OFF and isolating one UPS while the other remains in service.

This operation is permitted only for a system configured in the “redundant parallel mode”.

1. In sequence, open the UPS switches Q4 (output), Q1 (rectifier input), Q2 (bypass input).

2. Open the battery circuit-breaker.

To completely isolate the UPS, open the a.c. power supply circuit-breaker (both circuit-breakers if
separate supplies are provided for the rectifier and the bypass supply) and the output circuit-breaker on
the power distribution switchboard.
If individual UPS output isolation circuit-breaker are not installed on the power distribution
switchboard, remember that voltage supplied by the UPS which remains in service will still be present
on the output terminals of the shutdown UPS.

Wait approximately 5 minutes before accessing the interior of the equipment to allow all the internal
capacitors to discharge.

7.3.5 Switching ON a UPS that was previously switched OFF and isolated from
the system.

1. Close the circuit-breakers relative to the shutdown UPS that were previously opened on the power

distribution switchboard.

2. Close the switches Q1 (rectifier input) and Q2 (bypass input) of the UPS.

3. Select the MEASUREMENT function from the display on the main menu, then press ENTER and

select BATTERY. Press ENTER and check that the voltage level has reached the rated value (432V
or 446V or 459V in accordance with the number of battery blocks).

4. Close the battery circuit-breaker.

5. Close UPS switch Q4 (output), wait about 20 seconds and check that the message NORMAL

OPERATION appears on the message page display.

7.4 Installation procedure (Common battery)

WARNING

If residual current circuit-breakers are used on the incoming side of the UPS modules, make sure to use a
common sensor for both rectifier incoming lines. At the instant of electrical connection, the current may not be
split instantaneously and this may cause the residual current circuit-breakers to trip separately.

Refer to the general diagram shown in figure 7-2.

In addition to the information described in paragraph 7.2, the 1+1 system with common batteries also
uses the ”battery auxiliary distribution box”. This box uses two isolators to connect the battery to the
two UPS modules, and thus individually isolate the two modules from the system.
The box is also designed to supply the two UPS modules with a battery current measurement (charge or
discharge).
Follow the instructions provided below to connect this option.

Use part no. 4641031 F (125 A) with the 30 kVA UPS.
Use part no. 4641032 G (250 A) with the 40 and 60 kVA UPS.

7.4.1 Connection between UPS and “battery auxiliary distribution box”

Refer to the diagram shown in figure 7-6 and the attached table.

1. POWER CABLES:
For the connection between the UPS modules and the auxiliary box use cables with the section

indicated in paragraph 3.3.2.

For the connection between the auxiliary box and the battery use 2 cables in parallel (for each of the

2 polarities) which have the section indicated in paragraph 3.3.2.

2. AUXILIARY CABLES:

Use multiple-core shielded cables with a section of 0.5 mm2. Connect the cables with the Fast-on

6.3x0.6 mm terminals contained in a bag inside the “auxiliary battery distribution box”.

The battery current transformer “T11”, mounted next to the battery fuse, inside the two UPS modules,
must be disconnected and removed. The cables, disconnected from the UPS wiring, must be re­connected to cable “D1” or “D2” as illustrated in figure 7-6.

The temperature sensor, contained in a bag inside the battery auxiliary distributio box, must be mounted
in the battery cabinet next to the sensor which was previously installed, and connected to the auxiliary
box through cable “B” as illustrated in figure 7-6.

7.5 System start-up and shutdown procedures (Common battery)

WARNING

The isolators Q1 and Q2, located in the “Auxiliary Battery Distribution Box”, must be operated following the
procedures described below. Incorrect operation of these isolators might cause the circuit-breaker located in the
battery cabinet to open or blow the battery fuse located in the UPS.

In the system start-up and maintenance by-pass configuration procedures, the operations must be
performed one at a time, going to the next one only after having completed the previous one on both
UPS modules.

7.5.1 System start-up

Follow the procedure for the single UPS by referring to paragraph 2.2.

After completing the operations described in point 4, and before going to point 5, close isolators
Q1 and Q2 located inside the “auxiliary battery distribution box”.

For a system configured in the “redundant parallel” mode, the first of the two UPS modules available
will change its state from “load on bypass” to “load on inverter” (turning on and off the relative leds on
the mimic panel) and will inhibit the “load on bypass” state on the second one. When the second one
becomes available, it will enter the “load on inverter” state and the relative led on its mimic panel will
turn on.
For a system configured in the “power parallel” mode, the two UPS modules will simultaneously
change the state from “load on bypass” to “load on inverter” when both will become available.

7.5.2 System maintenance by-pass configuration procedure

Follow the procedure for the single UPS by referring to paragraph 2.3.
After completing the operation, open isolators Q1 and Q2 located inside the auxiliary box for common
battery.
For a system configured in the “redundant parallel” mode, the changeover from “load on inverter” to
“load on bypass” will take place only when the operation described in point 4 has been completed on
both UPS modules.

7.5.3 Procedure to switch the system from the maintenance by-pass mode to

the normal operating condition

Follow the procedure for the single UPS by referring to paragraph 2.4.

After completing the operations described in point 2, and before going to point 3, close the
isolators Q1 and Q2 located inside the “auxiliary battery distribution box”.

7.5.4 Switching OFF and isolating isolation one UPS while the other remains in
service.

This operation is permitted only for a system configured in the “redundant parallel mode”.

1. In sequence, open the UPS switches Q4 (output), Q1 (rectifier input), Q2 (bypass input).

2. Open the isolator located inside the battery auxiliary distribution box, relative to the UPS that is

being excluded.

To completely isolate the UPS, open the a.c. power supply circuit-breaker (both circuit-breakers if
separate supplies are provided for the rectifier and the bypass input) and the output circuit-breaker on
the power distribution switchboard.
If the output circuit-breaker of the single UPS is not installed on the power distribution switchboard,
remember that voltage supplied by the UPS which has remained in service will still be present on the
output terminals of the shutdown UPS.

Wait about 5 minutes before accessing the interior of the equipment to allow all the internal capacitors
to discharge.

7.5.5 Switching ON a UPS that was previously switched OFF and isolated from
the system.

1. Close the circuit-breakers relative to the shutdown UPS that were previously opened on the power

distribution switchboard.

2. Close the switches Q1 (rectifier input) and Q2 (bypass input) of the UPS.

3. Select the MEASUREMENT function from the display on the main menu, then press ENTER and

select BATTERY. Press ENTER and check that the voltage level has reached the rated value (432V
or 446V or 459V in accordance with the number of battery blocks).

If this occurs, proced the next step.
If this does not occur and a voltage close to 0V is measured, this means that the active UPS is
