WARNING

HIGH EARTH LEAKAGE CURRENT: EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING THE
INPUT SUPPLY.

This equipment must be earthed in accordance with local electrical authority codes of practise.

Caution

This equipment can be fitted with RFI suppression filters (optional).

Earth leakage current exceeds 3.5 mA and is less than 1000 mA.
Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken
into account when selecting instantaneous RCCB or RCD devices.
Residual Current Circuit Breakers ( RCCBs ) must be selected sensitive to DC unidirectional pulses ( class A ) and
insensitive to transient current pulses.

Note also that the earth leakage currents of the load will be carried by this RCCB or RCD.

WARNING

This system has a signal available for use with an automatic device, externally located, to protect against
backfeeding voltage through the mains Static Bypass circuit. If this protection is not used with the switchgear that
is used to isolate the bypass circuit, a label must be added at the switchgear to advise service personnel that the
circuit is connected to a UPS system.
The text is the following or equivalent:

ISOLATE THE UNINTERRUPTIBLE POWER SYSTEM

BEFORE WORKING ON THIS CIRCUIT.

The warning triangle indicates all the personal safety instructions.

Follow these instructions carefully to avoid injury.

Single or '1+N' UPS System Liebert Hipulse E Installation Manual

Page vi (07/04)

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 minimized 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.

WARNING

Follow these instructions scrupulously:

The Liebert Hipulse E is designed exclusively for indoor use. Protect the unit from excessive condensation and
install it in a place free of flammable liquids, gases and corrosive substances.
Electrical installation must be performed by a qualified electrician.
Personnel working with the equipment described in this manual must be thoroughly familiar with the product.
Before making connections inside the unit, make sure that all incoming power sources are de-energised and
insulated.
When the incoming power source is active, the unit contains a dangerous level of voltage, even when it has
“maintenance bypass” status.
To insulate the unit, turn it off and insulate all incoming power sources and auxiliary power sources.

Part I – Installation Manual

1 Chapter 1 - Installation Procedure

1.1 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 all equipment not referred to this manual is shipped with details of its own mechanical and
electrical installation.

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 with water.
For more details, see Chapter 3 ‘Battery Installation’

Note

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

This section describes the UPS system's environmental requirements and mechanical considerations that must be taken
into account when planning the positioning and cabling of the UPS equipment.

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.

Installation (Mechanical) Single or '1+N' UPS System

Page 1-2 (07/04)

1.2 Environmental considerations

1.2.1 UPS location

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 (see Chapter 5  UPS Environmental).
All models in the 'Hipulse' UPS range are cooled with the aid of internal fans.
Cooling air enters the devices through the ventilation grids located at various points on the cabinet and is released
through the grids on the roof. To permit air to enter and exit and prevent overheating or malfunctioning, do not cover
the ventilation openings.
When the cabinet is located on a raised floor, and bottom cable entry is used, additional cooling air also enters the UPS
via the floor void. If necessary, 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.

Note 1: When batteries are cabinet-mounted adjacent to the UPS module, it is the battery which dictates the designed
maximum ambient temperature, not the UPS.

Note 2: Power losses from the System which may be used in an air conditioning system are intended for operation
using the Inverter, as in the ECOMODE configuration they would be undersized.

Air filters:

The optional dust filters can be installed behind the air intake in the front door(s). By opening the front door, the
filters can be changed easily without exposing personnel to high voltage. A schedule for inspection of the air filters
is required. The period between inspections will depend upon environmental conditions.

1.2.2 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.
If the batteries are rack-mounted, or otherwise located remote to the main UPS cabinet, a battery circuit breaker must be
mounted as close as possible to the batteries themselves, and connected using the most direct route possible.
The battery circuit breaker controller board (P\N° 4520079F) must be used in conjunction with the battery circuit
breaker.
This control board, which should be located near to the battery circuit breaker, interfaces with the UPS control system.

1.2.3 Storing

If unit is to be stored before installation, it is recommended to store the unit in a dry environment with temperatures in
the range of -25°C to 70°C. Use original packing materials or other suitable means to keep the unit clean.

1.3 Mechanical Considerations

1.3.1 System composition

A UPS system can comprise a number of equipment cabinets, depending on the individual system design requirements

- e.g. UPS cabinet, External Bypass cabinet. In general, all the cabinets used in a particular installation are of the same
height and designed to be positioned side-by-side to form an aesthetically appealing equipment suite.
Refer to the drawings provided in Chapter 6 for the positioning of the cabinets described below.

1.3.2 Frame and enclosure

The UPS is housed in an IP20 enclosure, designed for floor mounting. The top and side removable panels are secured
to the chassis by screws. The door can be opened to give access to the power connections bars, auxiliary terminal
blocks and power isolators. Front door can be opened at 180° for better Service and more flexibility in installations.
The UPS comes with an operator control panel, which provides basic operational status and alarm information. The
cabinet houses the power components, control boards and fuses. The cabinet is structurally designed to handle lifting
from the base. Cooling is by internal removable fans.

1.3.3 300 kVA UPS with rectifier 6 pulses

The 300 kVA UPS consists of a single cabinet.

1.3.4 300 kVA UPS with rectifier 12 pulses

While the 6 pulse 300 kVA UPS consists of a single cabinet, the 12 pulse 300 kVA UPS is divided into two cabinets
for easier transport and positioning at the installation site; one cabinet contains the standard UPS sections, while the
other contains the section including the second rectifier bridge, the magnetic components and the control circuits.
Once the equipment is in position, and before it is anchored in place permanently

, make the electrical power and

auxiliary connections and mechanically join the two cabinets of the UPS.

1.3.5 400 kVA UPS with rectifier 6 pulses

The 400 kVA UPS is split into two cabinets to allow easier transportation and positioning, one houses the Inverter and
the other houses the Rectifier/Static Bypass. Once the equipment is positioned and prior to fixing the equipment in
place, the two cabinet have to be bolted together and the interlinking power and control cable connections made.

1.3.6 400 kVA UPS with rectifier 12 pulses

The 12 pulse 400 kVA UPS also consists of two cabinets, but while it has the same overall length as the 6 pulse
version, it incorporates the 12 pulse section in the Rectifier/ Static Bypass cabinet.

1.3.7 Moving the cabinets

The route to be travelled between the point of arrival and the unit’s position must be planned to make sure that all
passages are wide enough for the unit and that floors are capable of supporting its weight (for instance, check that
doorways, lifts, ramps, etc. are adequate and that there are no impassable corners or changes in the level of corridors).

WARNING

Ensure any lifting equipment used in moving the UPS cabinet has sufficient lifting capacity.

EXERCISE EXTREME CARE WHEN HANDLING UPS CABINETS TO AVOID EQUIPMENT
DAMAGE OR INJURY TO PERSONNEL.

Ensure that the UPS weight is within the designated surface weight loading (Kg/cm2) of any handling equipment. See
the UPS specification for weight details - see Table 5-3.
UPS and optional cabinets (battery cabinets, top cable entry cabinets, etc.) can be handled by means of a fork lift or
similar equipment. For operations with a fork lift, it is necessary to remove either the lower protection panel located at
the base of the cabinet and rear panels (or both side panels). Be aware of the location of the load supporting feet so as
not to damage them, refer to installation drawings in Chapter 6.
In the eventuality that the equipment cannot be moved by fork lift, then rollers should be used.
Because the weight distribution in the cabinet is uneven, use extreme care during handling and transporting.
When moving the unit by forklift, lift the unit from the rear so as to protect the front panel. Do not exceed a 15 degrees
tilt with the forklift. Bottom structure will support the unit only if the forks are completely beneath the unit.

The handling with straps is not authorised.
Note: Do not move the battery cabinet with the batteries fitted.

Installation (Mechanical) Single or '1+N' UPS System

Page 1-4 (07/04)

1.3.8 Clearances

Liebert Hipulse E has no ventilation grills at either side or at the rear of the UPS. To enable routine tightening of power
terminations within the UPS, it is recommended that service access of 800 mm (minimum) be allowed for at the rear.
Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors
fully opened. It is important to leave a distance of 800 mm between the top of the UPS and the ceiling of the room in
which it is installed to permit adequate circulation of air coming out of the unit.

1.3.9 Floor installation

The installation diagrams in Chapter 6 of this manual identify the location of the holes in the base plate through which
the equipment can be bolted to the floor. 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. Refer to the base view to design this pedestal.

1.3.10 Fixing of the magnetic components

Before the equipment is in place, remove the transportation restraints that hold the input inductance and output
transformer in place.

1.3.11 Cable entry

Cables can enter the UPS cabinet from bottom.

Note

When selecting the power cables for side entry to a module located on a solid floor, consideration
must be given to the minimum permissible radius of the proposed cables to ensure that they can be
fashioned to reach the UPS connection busbars.

1.3.12 Top Cable entry

Optionally a top cable entry extension may be used, see the figures in Chapter 6.
The cabinet extends t he overall width of the UPS and permits connection of all incoming AC/DC power cables from above
through horizontally supported copper bars.
The top cable entry option is fitted on the side of the UPS cabinet and is supplied without side panels; the side cover
from the UPS being used.

The cabinet with cables coming in from the top for the 300 kVA UPS must be positioned on the right side, whereas
the cabinet for the 400 kVA UPS must be positioned on the left side.

This facilitates cable entry through the top aluminium panel after the appropriate cable entry holes have been cut. Roof­mounted eyebolts are fitted on shipment to optional cabinet, to enable the cabinet to be crane-handled. These can be
removed once the equipment has been finally positioned.

Note 1: The top cable entry also includes the power connection cables between the cabinet and the UPS.

Note 2: For special installation requirements regarding the position of the optional unit for incoming cables entering

from the top, special alternatives to the standard position are available.

1.4 Preliminary Checks

Before you install the UPS hardware you should carry out the following preliminary checks:

1. Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification,
paying particular attention to the ambient temperature and air exchange system.

2. Remove any packaging debris, then visually examine the UPS and battery equipment for transit damage, both
internally and externally. Report any such damage to the shipper immediately.

1.4.1 Identification

The equipment supplied has an identification tag on the back of the main door reporting:
the type, size, and main calibration parameters of the UPS. A metal disk fastened to the inside top of the cabinet is
engraved with its serial number.

Record the model and serial numbers in the table at the beginning of this installation manual. A record of this
information is necessary should servicing be required.

Installation Manual Liebert Hipulse E Chapter 2 - Installation Procedure

(07/04) Page 2-1

2 Chapter 2 - Installation (Electrical)

The UPS requires both «power» and «control» cabling once it has been mechanically installed. All «control» cables,
whether screened or not, should be 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.

2.1 Power Cabling

WARNING

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.

For cable entry, refer to section 1.3.11.

2.1.1 System Configuration

The main factors affecting the choice and size of cable are voltage, current (also taking into account overcurrent), room
temperature and conditions of installation of the cable.

Note: Correct cable size must also take into account the system’s overload capacity (see Chapter 5 – Technical
Specifications: - Electrical Characteristics).

The power cables of the system must be size with respect to the following description:

Module input cables

The module input cables must be sized for the maximum input current, including the maximum battery recharge
current, given in table 2-1, with respect to the module rating and the input a.c. voltage.

WARNING (300 kVA UPS)

Note 1: For split Bypass operation ensure that the busbars (*) between Bypass and Rectifier input are removed.

Note2: With a Class ‘A’ EMC filter (optional) and a ‘common’ input configuration, the capacitors on the

Rectifier input bars must be removed.

WARNING (400 kVA UPS)

Note: for a common input power configuration (single supply) interconnecting cables are required, connecting the

rectifier input with the bypass input (links about 1.5m long), with cables sized for the maximum input current in table
2-1.

Module Bypass and output cables

The bypass and output cables must be sized for the nominal output current, given in table 2-1, with respect to the
module rating and the output a.c. voltage.

Battery cables

Each UPS module has its own battery, which is connected using two cables, one positive and one negative. The battery
cables must be sized for the battery discharge current at the end-of-discharge voltage, as given in table 2-1 with respect
to the module rating.

Chapter 2 - Installation Procedure Liebert Hipulse E Installation Manual

Page 2-2 (07/04)

2.1.2 Table for determining power cable size

The table below gives nominal currents for determining the size of UPS power cables. Other factors, which must be
taken into consideration include cable route length, coordination with protective devices, etc.

The power cables can be sized to suit the UPS module rating according to the table below:

2.1.3 General Notes

The following are guidelines only and superseded by local regulations and codes of practice where applicable:

1. Take special care when determining the size of the neutral cable, as current circulating on the neutral cable may be
greater than nominal current in the case of non-linear loads. Refer to the values given in the ‘UPS Electrical
characteristics’ table in Chapter 5.

2. The earth conductor should be sized according to the fault rating, cable lengths, type of protection, etc. The earth
cable connecting the UPS to the main ground system must follow the most direct route possible.

3. Consideration should be given to the use of paralleled smaller cables for heavy currents, as this can ease installation
considerably.

4. When sizing battery cables, a maximum volt drop of 3Vd.c. is permissible at the current ratings given in Table 2-1.

5. In most installations, especially those concerning parallel multi-module systems, the load equipment is connected to
a distribution network of individually protected busbars fed by the UPS output rather than being connected directly
to the UPS itself. Where this is the case the UPS output cables can be rated to suit the individual distribution
network demands rather than being fully load-rated.

6. When laying the power cables, do not form coils, so as to avoid increasing formation of electromagnetic
interference.

7. In parallel multi-module systems, the output cable of each unit should be kept as equi-distant as possible between
the unit output terminals and the parallel distribution busbar to prevent from affecting the shared current.

2.1.4 Cable connections

The rectifier input, bypass, output and battery power cables ( all require lug type terminations ) are connected to
busbars situated below the power isolator switches - as shown in Chapter 6. These are accessible when the power
compartment cover plate is removed.
A terminal block X3 is used for connecting the control cables to the battery circuit breaker and a second terminal block
X4 is used for the external emergency stop facility, external OFF inverter, ext. Bypass, etc. these are female spade type
connections ( Fast-on 6,3 x 0,8 ) and are described later in Section 2.3.

2.1.5 Safety earth

The safety earth bus-bar is located near the input and output power supply connections as shown in Chapter 6. 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.

Note: Proper grounding considerably reduces problems in systems caused by electromagnetic interference.

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.

Single or '1+N' UPS System Installation (Electrical)

(07/04) Page 2-3

2.1.6 Protective devices

For safety reasons, it is necessary to install, external to the UPS system, circuit breaking protective devices in the input
a.c. supply and towards the battery. Given that every installation has its own characteristics, this chapter provides
general useful information for qualified installation engineers, with knowledge of operating practices, of regulatory
standards, and of the equipment to be installed.

Rectifier and Bypass input supply of the UPS:

Protection against excessive overcurrents and short circuits in the mains supply input:

These inputs must be protected, installing suitable protective devices at the distribution panel of the incoming main
supply, considering that the protection should discriminate with overload capacity of the system (see Chapter 5 
Specification: - Electrical Characteristics).

Split bypass: in the case of a split bypass being used, separate protective devices should be installed in the incoming
mains distribution panel.
The protective devices must be selected for the nominal input current, with respect to the UPS rating and the input a.c.
supply voltage as given in table 2-1.

Protection against earth faults (RCD devices):

In the event of a differential (RCD) device being installed upstream of the input supply, one must take into account the
transient and steady state earth leakage currents that are produced during start-up of the UPS.
The presence of an RFI suppression filter inside the UPS, determines a residual earth current greater than 3.5 mA and
less than 1000 mA.
Residual current circuit breakers (RCCB) must be sensitive to d.c. unidirectional pulses (class A) in the network and
insensitive to transient current pulses.
They are identified by the symbols respectively:

These isolators must have an average sensitivity, possibly adjustable between 0.3 and 1A.
It is recommended that the selectivity with every differential switch be verified both upstream of the input distribution
board and downstream (towards the load).

Parallel 1+N:

Use of differential circuit breakers on UPS unit inputs in a configuration with separate inputs and one battery for each
unit requires installation of a common device only on the system bypass mains.
Use of differential circuit breakers on UPS unit inputs sharing a common battery requires installation of a device
common to all the input lines. If inputs are configured for separate mains, a common device will also be required for all
System bypass mains.

UPS Battery:

The UPS Battery is protected by means of a control circuit that operates the tripping mechanism of an automatic
circuit breaking device (having a variable trip setting). The tripping mechanism using an undervoltage release coil
that operates on a preset minimum voltage level.

The circuit breaker is essential for maintenance of the battery and is normally located near to the battery installation.
The characteristics and operation of the automatic circuit breaker are given in Chapter 3.

Output of the System:

In the eventuality that an external distribution panel is used for load distribution, the selection of protective device must
provide discrimination with those that are used at the input to the UPS module.

2.3.1 Battery Control

The battery circuit breaker is controlled by the battery circuit breaker controller board, which is located within the
battery cabinet — or adjacent to the battery circuit breaker when the batteries are rack-mounted. This board controls the
circuit breaker's undervolt release coil and also provides a path for the circuit breaker auxiliary contacts to signal the
circuit breaker status back to the UPS control logic. All connections between the controller board and the UPS module
are made via the auxiliary terminal block (X3), which is located in the base of the UPS cabinet.

Figure 2-1 Auxiliary terminal block detail

Connect the battery circuit breaker control and temperature compensation cables between the UPS auxiliary terminal
block and battery circuit breaker controller board as shown in figure 2-1. These cable must be shielded and double
insulated, shield should be connected at protective earth of battery cabinet or battery breaker, not at UPS.

Caution

If battery temperature compensation is not used the system must be de-activated by the commissioning engineer.

2.3.3 Emergency Stop

If an external Emergency Stop facility is required it is connected to terminals 5 & 6 of the Auxiliary Terminal Block
(X4) and connected to the `normally closed' remote stop switch between these two terminals using shielded cable. If
this facility is not used then terminals 5 & 6 must be linked-out as shown in Figure 2-1.

Note 1

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

Note 2

Terminals 11 & 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).

2.3.4 Back Feed Protection

Using an auxiliary terminal (pins 9-10 of connector X4) the UPS provides a normally open contact to be used for
opening of an external circuit protection device, to protect the operator against backfeed of energy resulting from a
short-circuit fault of the Bypass line SCRs. This auxiliary contact can be used, for example, in series with an external
low voltage source, in order to supply the trip coil of an automatic circuit breaking device, located upstream of the UPS
Bypass mains input. In the event of energy being backfed the auxiliary circuit will activate closing the normally open
contact and as a result opening of the external circuit breaking device; the UPS is disconnected from the Bypass mains
supply. The electrical characteristics of the auxiliary contact are 50V (a.c. or d.c.) @ 1 Amp.

2.3.5 Fan Failure Alarm Indicator (Optional)

Liebert Hipulse E is designed to allow the installation of a device to control the correct operation of fans.
The kit includes the Fan Failure Alarm Indicator, interconnection components (loose and anchored connector) and
related wiring. This function employs an electromagnetic device installed on each individual fan, which gives an alarm
signal on the operator display panel and turns on a Led on the Fan Failure Alarm Indicator in the event that a fan slows
down or shuts down entirely.
If an alarm displays on the operator control panel, determine the physical location of the faulty fan using the
identification lable placed next to the "Fan Failure Alarm Indicator card".
A remote signal may be provided by installing appropriate alarm interface cards.

2.3.6 Battery ground fault detection (Optional)

To guarantee a continuously uninterruptible power supply to the critical load, single module UPS or parallel UPS
systems are provided with external batteries, so the battery insulation to PE (Protection Earth) shall be monitored to be
in a safe range. For this purpose the battery system is fitted with a DC monitoring device to detect and eliminate earth
faults to ensure operational continuity, this is included in a Battery Fault Detection Set.
The Battery Ground Fault Detection is the same for all UPS sizes.
When a battery ground fault is detected, an alarm will appear on the display panel (if the interface card is installed
within UPS and X6 jumper has fitted on 2-3).
A remote warning may be provided by installing an other alarm interface card.

The Battery ground fault detection (P/N 4645313X) contains fault detection device only. The wiring cables are already
installed within UPS. This option is fitted on DIN guide as shown in the installation drawings in Chapter 6.

3 Chapter 3 - Battery Installation

3.1 Introduction

The UPS battery consists of battery blocks connected in series to provide a nominal d.c. input voltage for the UPS
inverter. The required ‘AUTONOMY TIME’ (the time that the battery can maintain supply to the load in the event of a
mains failure) is limited by the ampere hour size of the individual battery blocks and in some cases this could mean
several strings are connected in parallel.
Usually, with UPS installations in the high power range covered by the 'Hipulse' equipment, the batteries are contained
in a dedicated battery room. It must be possible to install batteries of various types and capacity in the battery room to
obtain the required autonomy characteristics.

If multiple sets of batteries connected in parallel are used to provide the required battery autonomy, each set should be
fitted with an isolating devices to permit work to be performed on one set of batteries while the others remain in
service.

It must be possible to disconnect the battery from the UPS module when undertaking maintenance or service
procedures. This is facilitated by means of a suitably rated circuit breaker which must be located as close as possible to
the battery terminals, and the power and control cables connected to the UPS using the most direct route possible. The
circuit breaker can be switched manually ON or OFF but should also contains an under-voltage release mechanism
(having a variable trip setting) which is used in conjunction with battery circuit breaker controller board.

For battery room assembly, Liebert offers a battery circuit breaker option (the rating of which depends on the size of the
UPS) including a battery circuit breaker controller board (the same for all sizes). This box is designed to be either wall­mounted or assembled on a frame, and is connected between the UPS and the battery. Refer to section 3.8 for more
information.
A Common Battery Circuit Breaker is available for systems incorporating two parallel UPSs with a common battery. It
comprises two switches, which may be used to section one UPS while the other remains active. Refer to section 4.3 for
more information.

Single or '1+N' UPS System

Page 3-2 (07/04)

3.2 Safety

Special care should be taken when working with the batteries associated with the 'Hipulse' UPS System equipment.
When all the cells are connected together, the battery terminal voltage will exceed 400V and is potentially lethal. A
primary safety consideration is to physically isolate the battery installation from all but appropriately qualified
maintenance personnel; which is best achieved by locating the cells in a dedicated battery room. Specific battery
cabinet and battery room design details are given later in this section.

WARNING

The following general battery safety precautions and WARNINGS should be observed at all times:

a) A battery can present risk of electric shock or burn from high short circuit currents.

b) When connected in a string the voltage could be 460V d.c. this voltage is potentially lethal always observe high

voltage precautions.

c) Only qualified personnel should install or service batteries.

d) Eye protection should be worn to prevent injury from accidental electrical arcs.

e) Remove rings, watches, necklaces, bracelets and all metal objects.

f) Only use tools with insulated handles.

g) Wear rubbers gloves and a rubber apron when handling batteries.

h) If a battery leaks electrolyte, or is otherwise physically damaged, it should be placed in a container resistant to

sulphuric acid and disposed of in accordance with local regulations.

i) If electrolyte comes into contact with the skin the affected area should be washed with plenty of clean water

immediately.

j) Batteries must always be disposed of according to local environmental laws.

k) When replacing batteries use the same number and type that were originally fitted.

l) Disconnect charging source prior to connecting or disconnecting battery terminals.

m) Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source of ground. Contact

with any part of a grounded battery can result in electrical shock.

3.3 UPS Batteries

Battery can be VRLA, Ni-Cd or wet cell type.
It is common practice in UPS installations to use valve regulated cells. The term ‘valve regulated’ is used currently in
place of either ‘sealed’ or ‘maintenance free’ both of which have been used in the past.
Valve-regulated cells are not ‘sealed,’ and will vent. The amount of gas given off is less than for a flooded cell but
when considering the design of the battery installation allowances must be made for adequate ventilation and heating of
the cells. Boost charging must not

be applied to valve regulated cells as this will cause them to overcharge and
subsequently vent.
Similarly, valve-regulated cells cannot be regarded as ‘maintenance-free’ as they must be kept clean and their
connections checked periodically for tightness and lack of corrosion. It is not possible to check the cells’ specific
gravity directly but the battery can be checked by the ‘CS PG battery service programme’ which can give an indication
of faulty cells or cell degradation within the battery.
Batteries are fully charged before delivery; however, storage and transportation times mean that, inevitably, some
charge is lost by the time the battery is commissioned. All the cells forming the battery should be brought to the same
state of charge and be recharged within 6 months of the factory charge.
It is especially important that the battery is fully charged before attempting a witness test of the autonomy time. This
may require several days to complete; therefore any witness test concerning the batteries should take place only after
the battery has been on uninterrupted float charge for at least one week.
Cell performance typically improves after a few weeks in service or after two or three discharge/recharge cycles.

Installation Manual Liebert Hipulse E Chapter 3 – Battery Installation
Single or '1+N' UPS System

(07/04) Page 3-3

3.4 Installation design considerations

Note:

Full safety instructions concerning the use and maintenance of UPS batteries are provided in the
appropriate battery manufacturers manuals. The battery safety information contained in this section
relates to key considerations which must be taken into account during the installation design process
and might affect the design outcome depending on localised conditions.

3.5 Battery Installation and Maintenance

3.5.1 Temperature considerations

Battery performance depends on the ambient battery temperature. Capacity and autonomy times are quoted for a new
battery operating at 20°C. Battery capacity is increased by 1% for every 1°C increase in temperature up to 25°C. If a
battery is used at temperatures above 25°C, its life is reduced; consequently its capacity and UPS autonomy time will
reduce more rapidly over a period of time. Operating below 20°C will reduce the battery capacity by approximately
1%-1.5% per 1°C. For example: if a battery discharge test is attempted during the middle of winter when the ambient
temperature is 5°C the battery capacity will be only 77.5% of its design value and will not satisfy its specified
autonomy time.
Ambient temperature, ventilation, spacing, float voltage and ripple current all affect the battery temperature. Uneven
temperature distribution through the battery string will cause the voltage distribution to be uneven which can also lead
to problems — it is therefore important to maintain a even temperature across the whole battery chain.
‘Valve-regulated’ cells are very sensitive to temperature and should be operated at a temperature between 15°C and
25°C. To help sustain this operating temperature range the battery is normally float charged at 2.25V/cell.
When batteries are mounted in the same room to the UPS module, it is the battery which dictates the designed
maximum ambient temperature, not the UPS. — i.e. in the case of ‘valve-regulated’ cells the ambient room temperature
should be kept between 15°C and 25°C, and not between 0°C and 40°C (which is the specified main equipment
operating temperature range). Temperature excursions are permissible for short periods of time provided the average
temperature does not exceed 25°C.

3.5.2 Battery population

The nominal DC bus voltage, and therefore battery float voltage, is set according the module’s rated input/output
voltage, and usually set to 432Vdc (380Vac), 446Vdc (400Vac) or 459V (415Vac). Given that the desired cell float
voltage is 2.25V, this means that a different number of cells are required in each case (see Chapter 5 - DC Intermediate
Circuit).

3.6 Battery protection

The battery is connected to the UPS through a circuit breaker which is manually closed and electronically tripped via
the UPS control circuitry. If the cells are rack -mounted (or located remote from the main UPS cabinet), this circuit
breaker, fitted within the cabinet, must be positioned as near as possible to the batteries themselves, and the power and
control cables connected to the UPS using the most direct route possible. The UPS electronic circuitry will trip the
circuit breaker if any of the following conditions occur:-

a) If the d.c. busbar drops below 330V d.c. (This would normally occur during a mains failure when the battery

autonomy time has been exceeded.

b) If there is a rectifier problem and the d.c. bus rises above (2.45 V/cell exceeded on the battery).

c) If the Emergency Stop is operated.

Note: All equipment servicing procedures should be carried out only by trained personnel.

3.7 Battery installation

3.7.1 Fitting & connecting the batteries

The following notes, in conjunction with the diagrams, illustrate the broad principles to be followed when fitting and
connecting the majority of battery installations.

3.7.2 Fitting the batteries

1. In general a minimum space of 10 mm must be left on all vertical sides of the battery block to permit free air

movement around the cells.

2. Clearance should be allowed between the top of the cells and the underside of the shelf above (this is necessary

for monitoring and servicing the cells).

3. When installing the batteries on racks always work from the bottom shelf upwards to prevent raising the centre

of gravity.

3.7.3 Connecting the battery

1. When the battery circuit breaker cabinet is installed on a raised floor the battery power cables and circuit

breaker control cables can be routed to the UPS cabinet via the floor of the cabinet. If the UPS and battery
circuit breaker cabinet are located adjacent to each other and located on a solid floor these cables can be passed
between the cabinets via the lifting apertures located in the lower sides of the cabinets.

2. In general it is recommended that the inter-connecting cables are fitted to the batteries within their particular

level before fitting the inter-level connecting cables, followed finally by the cables to the circuit breaker.

3. An insulating shroud should be fitted to each terminal after its connection has been made.

4. When connecting the cables between the battery extremities to the circuit breaker always connect the circuit

breaker end of the cable first.

3.7.4 Battery room design

Whatever the type of mounting system selected, the following conditions should be noted:

 Layout of cells:

Whatever battery mounting system is used, the batteries should be laid out in such a manner as to make simultaneous
contact with two exposed live parts having a potential greater than 150V impossible. Where this is not possible,
insulated terminal shields must be installed and insulated cables must be used for connections.

 Service platform:

The service platform (or duckboard) must be slip-proof, insulated from the floor and be at least one metre wide.

 Connections:

All connections must be as short as possible.

 Battery protection circuit breaker:

The battery circuit breaker is generally installed at the front of the battery room. The connection of Circuit Breaker Box
available for the 'Hipulse' is described in the following paragraph.

Figure 3-1 Battery Room Design

Installation Manual Liebert Hipulse E Chapter 3 – Battery Installation
Single or '1+N' UPS System

(07/04) Page 3-5

3.8 Battery circuit breaker box

The box contains a battery isolating circuit breaker and the circuit breaker controller board (P/N 4520079F) as also
mounted in the Battery cabinet.
A range of battery circuit breaker boxes is available for use in installations where the battery is not installed in the
battery cabinet, in which case the appropriate battery box is fitted as close as possible to the battery and connected
to the UPS equipment as illustrated in Figure 3-4.

The battery circuit breaker box, used with the circuit breaker controller board, is required to protect the battery from
deep discharging and overcurrents. It also provides electrical isolation between the UPS and the battery, permitting
technical service personnel to reduce the risks involved in maintenance work to a minimum. Inside the box are
connection bars for power cables arriving from the UPS and from the battery.

Note: The control cables from the UPS module to the controller board must be made using a 5-core shielded cable
located in a separate conduit to that containing the battery power cables.
The control signal cable is connected to the circuit breaker controller board (P/N 4520079F) through the terminal board
(X1).
The cable shield must be earthed to prevent induced noise affecting the control operation, and a separate safety earth
must be connected between the UPS module and Circuit Breaker Box.

The battery circuit breaker boxes are of the same size (save for height) for both the 300 kVA and the 400 kVA UPS,
but switch capacity and the section of the connection bar are different.

3.8.1 Battery Temperature Board (Optional P/N 4532029V)

A battery temperature sensor card, supplied separately from the battery circuit breaker, is connected with the UPS logic
through the battery circuit breaker control card.
With this feature fitted, the nominal float voltage supplied to the battery is adjusted so as to be inversely proportional to
the ambient battery cabinet/room temperature. This prevents the battery being over charged at high ambient
temperatures.

Installation Manual Liebert Hipulse E Chapter 4 - ‘1+N’ System
Single or '1+N' UPS System

(07/04) Page 4-1

4 Chapter 4 - 1+N System

4.1 General

The 1+N system has two or more (up to a maximum of six) modules of the same size (kVA). The load is equally
divided between the units that form the system. The system can be of two types:

• Parallel power

All the UPS's are able to provide the full power requested for the load.

• Parallel redundant

The system comprises a higher number of UPS's able to provide the full power required for the load.
For more detailed information on the operating principle of 1 + N parallel systems, see Chapter 7.

The 1+N system is used to:

• Increase the reliability of the system in order to ensure a good supply to the critical load connected.

• Increase the power availability (system expansion) in the event an unforeseen power demand occurs. This

guarantees a greater flexibility in relation to the critical load connected.

• Increase serviceability and allow the execution of maintenance operations and reparations without affecting the

ordinary operating conditions of the system (depending on the redundancy level).

The system can comprise of up to 6 UPS modules of the same power rating connected in parallel without the need for a
centralized mains static bypass.
The following components are installed inside each UPS unit in the 1+N parallel system:
The parallel logic board, the parallel connector board and the corresponding flat connection cables.
From a ‘power’ viewpoint each module is internally identical to the ‘single module’ configuration. A 1+N parallel
system requires inverter and bypass supplies, inter-module control signals to manage current sharing, synchronizing
and bypass switching between the modules. In figure 4-1 this is shown as the ‘inter-module control bus’, which is
facilitated through the use of multi-way ribbon cables connected between the units of the system.
The number and length of these flat cables is determined by the positioning of the equipment in the system, so this
supply is determined when the order is placed.

If the load is transferred onto a static bypass line, in a configuration in which three or more units are connected in
parallel, there may be a problem dividing up currents on the power circuit. Each case is different, and depends on the
length of the cables used, for example the resistance upstream and downstream of the static bypass line.
The differences between the impedances could result in undesirable division of currents over one or more UPS units.
This problem may be solved by including an optional inductance on the static bypass line of each UPS unit.

Note: For each additional UPS unit, the operator control panel must be programmed with the correct size and the
configuration of the static switch must be identified as ‘internal’.

1 + N Configuration (>2 UPS's) or two UPS's with parallel power connection

IMPORTANT

(*) With configurations consisting of two UPS's with parallel power or 1+N systems integrated with more than two

UPS's, where the load level is above the rated power of the single UPS, it is necessary to install an adequate
external maintenance bypass. It is also necessary to adopt all the measures required to prevent the internal manual
bypass switch of the UPS (Q3) from being used. This can be done by removing the handle of the switch and by
placing a warning label for the maintenance personnel.

For information on the external maintenance bypass, see paragraph 4.4.

4.2 Installation procedure

4.2.1 Preliminary Checks

Be sure that a parallel kit is present and fitted in each of the modules, and that the modules are of the same rating and
with the same SW and HW release (See paragraph 8.1.2 of the User Manual  The Menu Options).

WARNING

Fitting of the parallel kits and board setting required to convert from Single Module to 1+N

must be made by Liebert Service & Support trained personnel.

4.2.2 Protective Devices

Refer to the instructions supplied in Chapter 2  Electrical Installation - Section 2.1.6.

4.2.3 Power cables

Input Bypass and Rectifier, outputs of modules

For power cabling the installation is the same for each module as described in Chapter 2.

4.2.4 Control cables

Inter-module control

Modules are interconnected as shown in Figure 4-2 using connections to the other UPS modules via the parallel
connector board with shielded 34-way cables.
These cables are connected between the 'N' modules to pass control signals which govern module synchronization, load
sharing, battery charge current sharing (in a common battery installation), load transfer operation and other general
control and alarm functions. These signals are necessary to ensure correct system operation, and built-in redundancy
allows the system to function if ever one of the 'N' cables becomes disconnected.

Inter-module Parallel Connections

1+N Parallel UPS System: Inside the module there is a parallel connection board (P/N 4590060U) mounted on the
right hand side of the Static Switch cabinet. Connect one end of the interconnecting ribbon cable to interface connector
(X1) of the first UPS module and the other end to connector (X2) of the second module, and so to the next module until
a closed loop is formed.

Cable entry is as identified in the mechanical drawings in Chapter 6.

4.2.5 Battery Control

The system is designed to operate with two different battery configurations:
◊ With separate batteries
Installation procedure is the same as for single module.
◊ With common battery (only for two units)

In order that the battery charge current is shared equally between the modules, a ‘common battery’ option kit is
available. (see Figure 4-6).

4.2.6 Emergency Stop (EPO)

The external emergency stop facility is identical to that described for the single module installation — that an individual
Emergency Stop button is provided for each module.
Note that this is a normally closed switch.

4.3 Common battery box (Option)

4.3.1 Common Battery box for two UPS in parallel

A common battery box is available to permit a common battery to be shared between two modules (see fig.4-6).
The box, which is used to connect the DC busbar of the two modules to a common battery, should be fitted as close
as possible to the UPS modules, with cabling preferably of the same length.

Warning

There is no protection to prevent closing a module's battery isolation switch when its rectifier is shut down. Such
operation will trip the battery circuit breaker and rupture the battery fuse in that module.

Before operating the module's battery isolation switch, the operator must first check that the battery voltage and
rectifier voltage different by less than 10% — this may be easily achieved by reading the Battery Voltage on the
Display Panels of both modules.

Control cable connections are required as shown in Fig. 4-5, this includes an extension of the inter-module cables
described in Section 4.2.4. In addition there are other auxiliary connections that are identified in the figure below.

4.3.1.1 Installation Procedure (Common Battery)

WARNING

If differential circuit breakers are used on UPS inputs, be sure to use a common device for all input lines. If the
configuration has inputs from separate mains, a common device will also be required for all the System’s bypass
mains.

A

t 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 4-3.

The 1+N parallel system with common batteries (only for two units) also uses the ”Common Battery Box” optional kit
(box type depends on UPS dimensions). 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).
The Common Battery includes protection fuses of the DC power supply (F1&2):
Type GL = Size 10x38 – 1A\500V.

4.3.1.2 Connection between UPS and “Common battery box”

Refer to the diagram shown in figure 4-5 and the attached table.

1. POWER CABLES:

For the connection between the UPS modules and the common battery box use cables with the section indicated in the
Installation Electrical (table 2-1).

2. AUXILIARY CABLES:

The auxiliary cables of the common battery box must be screened and double insulated.
The screen is connected to the earth of the common battery box.
Use multiple-core shielded cables with a section of 0.5 to 1 mm

2

.

Connect the cables with the Fast-on 6.3x 0.8 mm terminals (female).

The temperature sensor, contained in a bag inside the Common Battery Box, must be mounted in the battery cabinet
next to the sensor which was previously installed, and connected to the Common battery box through cable “B” as
illustrated in figure 4-5.

Note: Power and auxiliary cables are not included in the supply.

4.4 Maintenance Bypass cabinet (Option)

Bypass cabinet enables maintenance operations and reparations to be performed in full isolation besides allowing the
disabling of each UPS without affecting the ordinary operation of the system (depending on the redundancy level).
The optional maintenance bypass cabinet must

be used in all configurations where the internal bypass is not

sufficient to guarantee the power requested by the load.

This cabinet comprises:

• A cut-off isolator for the direct line, which disconnects the bypass line from the load

• Two isolators (see Note 1) to cut-off single UPS outputs

• A cut-off isolator for the output of the whole UPS system

• A terminal block for the auxiliary connections to the UPS's

Note (1): there are alternative solutions differing from suggested standard for specific installation requirements (i.e.
with several UPS cut-off isolators).

Study the reference drawing provided in Chapter 6.

WARNING

Carefully follow the operating procedures provided in this manual to completely disable the UPS. It is useful to
remember that all input/output power and battery switches must be open for the UPS to be completely insulated.

The UPS system with external maintenance bypass cabinet offers a standard protection that guarantees the blocking
of the inverter and the switching of the load to the bypass line if the maintenance bypass switch is accidentally
closed.

4.4.1 Auxiliary connections between the maintenance bypass cabinet and two UPS's

The maintenance bypass box connected to the terminal blocks requires specific control cabling, as described here

4.4.2 Castell Interlock

The Castell Interlock enables the operator to close/open the external maintenance bypass switch following the
procedure required to release/insert the key. The UPS Liebert Hipulse E system offers two types of Castell Interlock
options: mechanical and electromechanical. The type must be selected depending on the configuration of the system
installed in the plant.

Castell Interlock

Configuration of the UPS system Type of Castell Interlock

Two UPS's with parallel redundant connection (1+1) Mechanical Castell Interlock

Two UPS's with parallel power or
above two UPS's (1+N)

Electromechanical Castell Interlock

The Castell Interlock option is normally used in combination with the power isolators placed inside the external
maintenance bypass cabinet.

Note: The Liebert Hipulse E UPS system is already pre-arranged for the installation of this option.

This option comprises:

• A Castell Interlock with key (BP1) for each UPS of the system. The key is normally blocked and released only

when the UPS inverter turns off and the load is switched to the static bypass, depending on the active UPS
modules.

• A Castell key exchange box. This will receive the keys from all the UPS modules, then release another key

(BP2) to use in the Maintenance Bypass isolator.

• A Castell Interlock with key (BP2), situated on the external maintenance bypass isolator. As this isolator is

normally open and has no key, it can be closed only with the key (BP2) released by the Castell key exchange
box. The key is released only when the isolator is open.

• A Castell Interlock with key (BP2), situated on the UPS output isolator within the external maintenance bypass

cabinet. This isolator is normally closed and has a key. The key is released only when the isolator is open.

4.4.2.1 Electromechanical Castell Interlock

This option consists of a Castell key exchange box and of several Castell units with individual key. Their number varies
according to the number of UPS's present in the system.
The release of a specific key (BP1) occurs only when the inverter turns off. As a consequence thereof, the load is
transferred to the internal static bypass line (the switching operation occurs when the number of active UPS's is lower
that the number set in the menu of the operator control panel). The key, which is fixed in position by means of an
electromechanical device, can only be removed by pressing the energising button of the solenoid and when the green
indicator is on. The keys extracted from the UPS's (n BP1) enable to free a second key (BP2) from the Castell key
exchange box and to close the external maintenance bypass isolator, enabling the line that directly connects the bypass
mains to the load. To isolate the UPS system, it is necessary to open the UPS output isolator of the external bypass
cabinet, the protective devices at the input distribution panel and the battery circuit breaker. At this point, the load is
supplied by the direct line inside the maintenance bypass cabinet and it is possible to perform maintenance operations
or reparations on the UPS as it is completely isolated.

4.4.2.2 Mechanical Castell Interlock

The description above is valid also for this type of Castell unit, with the following exceptions:

• The maintenance bypass switch (Q3) of the UPS is closed before the external bypass isolator.

• The key (BP1) acts on the maintenance bypass isolator (Q3) blocking (or disengaging) a mechanical stop.

• No button needs to be pressed to extract the key (BP1) on the UPS.

The keys symbols of the Castell Interlocks can be customized to suit the needs of the customer.

Part II – User Manual

7 Chapter 7 - General Description

7.1 Introduction

The Liebert Hipulse E 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.

7.2 Design Concept

7.2.1 Introduction

This section describes an individual module's operating principles. The UPS basically operates as an a.c. -d.c. -a.c.
converter (see figure 7-1). 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. bus-bar.

Figure 7-1 Single Module block diagram

The d.c. bus-bar produced by the rectifier provides both battery charging power - being equipped with 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.

7.2.2 Bypass supplies

The circuit block annotated ‘Static Switch' in figure 7-2 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'. During normal system operation the load is connected to the inverter and the 'inverter-side' of the Static Switch is
closed; but in the event of a UPS overload, or inverter failure, it is automatically transferred to the static bypass line.

Figure 7-2 UPS power switches configuration

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. 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.

A 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 routine maintenance.

Note: The load equipment is not protected from normal supply aberrations when operating on Bypass side or in the
maintenance bypass mode

7.2.3 System Control Philosophy

Normal operation

During normal operation, i.e. when the UPS input supply is present and within specification, both the rectifier and
inverter sections are active and the static switch is turned on to connect the inverter output to the critical load busbars.
The battery circuit breaker is also closed and the battery is therefore permanently float charged at the d.c. busbar
voltage level.
(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.

A module's static switch cannot close until these conditions are satisfied

Mains Failure

If the power mains has a failure or is out of tolerance the rectifier will stop automatically, while the Inverter will
continue to operate on power from the battery for a period of time which depends on the load and the capacity of the
battery. If the mains supply has not returned within this time, the Inverter will stop automatically and an alarm message
will appear on the UPS operator control panel display.
Critical load will not be interrupted in the event of a drop or return of the AC power mains.

Return of power mains

When the mains returns within the required tolerance, the Rectifier will start up again automatically and gradually
(power walk-in), supplying power to the Inverter and recharging the battery at the same time. There will be no
interruption of the critical load.

Input Power Walk-in

The rectifier/charger provides a feature that limits the total initial power requirements to 20% of rated load and
gradually increases power up to 100% of full rating over an hardware selectable time (slow or fast).

Off-Battery

If the battery system only is taken out of service for maintenance, it is disconnected from the rectifier/charger and
inverters by means of (an) external disconnect breaker(s). The UPS shall continue to function and meet all of the
specified steady-state performance criteria, except for the power outage back-up time capability.

Power Walk-in delay timer

On 1+N parallel systems, it is possible to select the start of each UPS after a power failure, by setting a suitable time
from the operator's display (ranging between 0 and 120 seconds). This function is particularly useful when a generator
is present on the input side because it enables to acquire power gradually.

UPS Module fault

In the event of an Inverter fault, the Static Transfer Switch will automatically transfer the load onto the bypass mains
with no interruption. In such an event, request qualified technical assistance.
(1+N Parallel UPS System) In the event of a fault in a unit, the unit’s Static Transfer Switch will automatically exclude
the unit from the system. If the system is still capable of providing the required load, the remaining units will continue
to supply the load with no interruption. When the units still present in the system are no longer capable of fulfilling
power requirements, the load will automatically be transferred onto the bypass mains. The load will be transferred with
no interruption if the Inverters are synchronised with the network; if this is not the case, there will be an interruption
lasting about 20 msec.

Overload

In the event of an overload at the Inverter output which lasts longer than the typical time/current (refer to Installation
Manual – Specifications), the Inverter will shut down and the Static Transfer Switch will automatically transfer the
load onto the bypass mains with no interruption. If the overload falls within the typical time/current that has been
specified, the load will be returned to the inverters when the power drops to a level which can be supported by the
number of active units in the system (parallel 1+N).
In the event of a short circuit in the output, the load will normally be transferred onto the bypass mains, which will
cause the Inverter to shut down; this switch is determined above all by the features of the protective devices in use in
the system.
In either case, an alarm message will appear on the UPS operator control panel display.

(1+N Parallel UPS System) The control logic system constantly monitors load requirements and controls the power
supplied by the UPS modules. In the event that an overload condition is sustained for greater than a preset time, the
load will transfer to the mains bypass supply, when the number of active modules are unable to satisfy load

Chapter 7 - General Description Liebert Hipulse E User Manual
Design Concept Single or '1+N' UPS System

Page 7-4 (07/04)

requirements. The load returns to the inverter supply if the power is reduced to a value that can be sustained by the
number of active modules in the system.

Maintenance Bypass

A second bypass circuit contained in the UPS cabinet, identified as the ‘Maintenance Bypass’ line is included to enable
a ‘raw’ mains supply to be made available to the load while facilitating a safe working environment for carrying out
scheduled UPS system maintenance or trouble shooting. The circuit is manually selected by the Maintenance Bypass
Isolator which can be padlocked in the OFF position.

WARNING

The internal maintenance bypass must not be used when the UPS system is comprised of more than two UPS
modules in parallel.

CAUTION:

If an automatic circuit breaking device is not present in the input distribution panel, there remains a

dangerously high voltage at the output busbars and also on the input busbars of the UPS module that is switched
off

7.2.4 ECOMODE (for single UPS only)

In this operating mode the System prefers to put the load on the Bypass Mains, with the Inverter on stand-by. The load
is switched over to the Inverter when the mains goes outside of standard frequency and voltage values (or the values as
modified using the operator panel when starting up the system). The ECOMODE configuration requires a different set­up in the default menu configuration, which may be prepared in the factory before shipment or during installation by
personnel trained in use of the System.

Note: In order to operate in ECOMODE, UPSs must be provided with compatible software versions:
The ‘UPS Logic’ card must be release 15.0 or later (the SW release of the cards may be read on the front panel display,
referring to Section 8.1.2  Operating Instructions).
Operating procedures in ECOMODE are the same as those described in Chapter 9, except that the load is normally on
the Bypass Mains, the Load led is normally on Inverter (5), and the corresponding alarm message will be replaced with
Load on Mains (6).

WARNING

In ECOMODE the load is not protected against mains distortion.

7.2.5 UPS Power Switch Configuration

Figure 7-2 illustrates the Liebert Hipulse E 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.

7.2.6 Battery circuit breaker

The battery should be 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.

7.2.7 Battery temperature compensation

Liebert Hipulse E UPS System offers a battery temperature compensation circuit. As the temperature at the battery
location rises the d.c. busbar voltage reduces in order to sustain the battery at its optimum charge voltage. This must be
used in conjunction with the battery temperature sensor board.

7.2.8 Socket outlet

Socket outlet of 1A current 250 Vca (max) handling capability is provided for the ease of testing, commissioning &
servicing of the UPS.

User Manual Liebert Hipulse E Chapter 7 - General Description
Single or '1+N' UPS System Design Concept

(07/04) Page 7-5

7.2.9 System Expansion

If necessary, a single-module system can be expanded to cater for an increased load requirement by adding additional
modules. Such forward planning should also take into account the physical space required by any additional UPS
modules, because any such modules must be situated adjacent to the existing system.
System expansion requires a change in the SETUP of the display panel.

Note: System expansion should be carried out only by trained service personal.

The individual modules connected to the system must be of the same power rating.

7.2.10 Frequency Converter

Liebert Hipulse E is designed to function with the output AC to your critical load, supplied at a different frequency to
the input mains.
The following frequency conversions are available:

1. 50 Hz input 60 Hz output

2. 60 Hz input 50 Hz output

When operating a single module as frequency converter the Liebert Hipulse E requires the static bypass operation to be
disabled and isolation of the input mains supply from your critical load. These modifications will be carried out by the
setting of internal links to inhibit the static switch operation, and isolation of the supply to the bypass isolator. As a
bypass is not required, it is easier to implement a frequency converter application by using a Multi Module Unit version
(MMU) Liebert Hipulse E module (see Figure 7-1). For requirements with different operating voltages the solution is to
use a standard MMU module with external adapter auto-transformer.

Figure 7-1 Example of frequency converter application

Bargraph Section

This following functional area shows the various UPS load and battery charging conditions.

16 Load Battery

The amber LED situated at the beginning of the % Autonomy bargraph illuminates when the battery voltage has

discharged to 1.8V/cell and indicates that the battery is approaching its low voltage cut-off point and the UPS will
shortly shut-down.

17 % Battery state Autonomy time bargraph

When the battery is being charged (normal) the five leds illuminate progressively to indicate the state of battery

charge as a percentage of a charge. When the battery is discharging (battery on-load) the bargraph function
changes to provide an indication of the remaining battery autonomy time.

With a fully charged battery all five LEDs are illuminated indicating than time remaining is dependent upon both
the battery A/Hr capacity and the applied percentuage load. An autonomy is determined from the type of battery
used, as the autonomy falls below this time the LEDs will extinguish in steps starting from the right-hand end.

18 % Load bargraph

The five leds illuminate progressively to indicate the applied load as a percentage of the rated maximum current,

increasing in 20% steps to 100% of full load when all five are illuminated.

19 Overload

The amber LED situated at the end of the % Load bargraph illuminates if the applied load exceeds 100% of the

module(s) rated output current. This indication will be accompanied by an audible alarm and an alarm message.

20 Emergency Stop — housed beneath a safety cover to prevent inadvertent operation

When the emergency stop 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,
emergency power off can be used to drive the external circuit breaker's trip circuit.

9 Chapter 9 - Operating Instructions

9.1 Introduction

The UPS can be considered to be in one of following 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.

• On Static Bypass - The load power is supplied though the mains static bypass line. This may be considered as

an intermediate operating condition being utilized for the purpose of load transfers between inverter and
maintenance bypass or supply under abnormal operating conditions.

• ECOMODE – All relevant power supply switches and the battery switch are on, and the load is fed by the

Bypass Mains through the UPS Static Transfer Switch, while the Inverter remains on stand-by.

This chapter contains instructions which enable you to switch between the above conditions, to carry out a RESET and
how to switch ON\OFF the inverter, etc.

9.1.1 General notes

Note 1: All the user controls and indicators (led) mentioned in these procedures are identified in Chapter 8.

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 Liebert Hipulse E 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 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.

9.1.2 Power Switches

The UPS can be separated by means of power switches, mounted inside the cabinet and accessible after opening the
front door, which has a key.
The location of the UPS power switches is shown in Figure 9-1.

The UPS module power switches are:
Q1 - Input Isolator: connects the UPS with the mains supply.
Q2 - Bypass Isolator: connects the UPS with the bypass supply.
Q3 – Maintenance Bypass Isolator (padlocked) permits supply of the load directly by the bypass line for maintenance

of the UPS module.

The internal maintenance bypass must not be used when the UPS system is comprised of more than two UPS modules

in parallel.

Q4 - Output Isolator: connects the output of the UPS to the load.

Note : The battery interrupter is not expected inside of the UPS and should be installed in the proximity of the
respective battery.
