For more details, refer to Chapter 9 .
Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved
accessories only.
WARNING: high earth leakage current
Earth connection is critical before connecting the input supply (include both utility supply and battery).
"Earth leakage current introduced by the UPS, in any configuration from 30kW to 150kW, exceeds 3.5 mA and is less than
1000 mA and complies with the requirements of IEC/EN 62040-1 / IEC/EN 60950-1" 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.
This equipment must be earthed in accordance with local electrical authority codes of practice.
WARNING: backfeeding protection
This system has a control 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 to the switchgear to advise service personnel that the circuit is connected to
a UPS system.
The text has the following meaning or is equivalent to: Risk of Voltage Backfeed: Before working on this circuit, Isolate
Uninterruptible Power System (UPS), then check for Hazardous Voltage between all terminals including the protective earth.

Components that can be maintained by user
All the equipment maintenance and servicing procedures involving internal access need special tools and should be carried
out only by trained personnel.The components that can only be accessed by opening the protective cover with tools cannot
be maintained by user.
This UPS full complies with “IEC62040-1 General and safety requirements for UPS”. Dangerous voltages are present within
the battery box. However, the risk of contact with these high voltages is minimized for non-service personnel.Since the
component with dangerous voltage can only be touched by opening the protective cover with a tool, the possibility of
touching high voltage component is minimized.No risk exists to any personnel when operating the equipment in the normal
manner, following the recommended operating procedures in this manual.
Battery voltage higher than 400Vdc
All the battery maintenance and servicing procedures involving internal access need special tools or keys and should be
carried out only by trained personnel.
SPECIAL CARE SHOULD BE TAKEN WHEN WORKING WITH THE BATTERIES ASSOCIATED WITH THIS EQUIPMENT.
WHEN CONNECTED TOGETHER, THE BATTERY TERMINAL VOLTAGE WILL EXCEED 400Vdc AND IS POTENTIALLY
LEATHAL.
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.

Chapter 1 Installation Of UPS Rack System 6
Chapter 1 Installation of UPS Rack Unit
1.1 Introduction
This chapter introduces the relevant requirements for positioning and cabling of the LIEBERT APM UPS Rack
System and related equipment.
Because each site has its requirements, it is not the aim of this chapter to provide step-by-step installation
instructions, but to act as a guide for the general procedures and practices that should be observed by the installing
engineer.
Warning: installation can only be done by authorized engineers
Do not apply electrical power to the UPS equipment before the commissioning engineer arrives at installation site.
The UPS should be installed by a qualified engineer in accordance with the information contained in this chapter. All the
equipment not referred to in this manual is shipped with details of its own mechanical and electrical installation information.
Note: 3-Phase 4-Wire Input Power is required
The standard LIEBERT APM UPS system of Emerson can be connected to TN, TT and IT AC distribution system (IEC60364-3)
of 3-phase 4-wire, and a 3-wire to 4-wire conversion transformer is provided as an optional part.If the system is connected to IT AC
distribution system, its input needs to be fitted with a 4-pole circuit breaker in accordance with relevant IT system standard.
WARNING: battery hazards
SPECIAL CARE SHOULD BE TAKEN WHEN WORKING WITH THE BATTERIES ASSOCIATED WITH THIS EQUIPMENT.
When connecting the battery, the battery terminal voltage will exceed 400Vdc 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.
1.2 Initial Checking
Perform the following checking operations prior to the UPS installation.
1. Visually examine if there is any damage inside and outside the UPS rack and battery equipment due to the
transportation. Report any such damage to the shipper immediately.
2. Verify the product label and confirm the correctness of the equipment. The equipment label is attached on the back
of front door. The UPS model, capacity and main parameters are marked on the label.
1.3 Location
1.3.1 UPS Location
The UPS is intended for indoor installation and should be located in a cool, dry and clean environment with adequate
ventilation to keep the environmental parameters within the specified operating range (see Tab. 9-2).

Chapter 2 Battery installation 7
LIEBERT APM UPS Module And Parallel System 30kVA~150kVA User Manual
The LIEBERT APM series UPS uses forced convection cooling by internal fans. Cooling air enters the module
through ventilation grills located at the front part of the cabinet and exhausted through grills located in the rear part of
the cabinet. Please do not block the ventilation holes.
If necessary, a system of extractor fans should be installed to aid cooling-air flow. An air filter should be used when
the UPS is to operate in a dirty environment and should be regularly cleaned to maintain airflow.
The cooling capacity of air conditioner should be selected according to the power loss data of UPS specified in Tab.
9-3: Normal mode (VFI SS 111 double-conversion UPS)
Note: The UPS should be installed on a cement surface or other surface that is not combustible.
1.3.2 External Battery Room
The battery will generate some amount of hydrogen and oxygen at the end of charging, so the fresh air volume of the
battery installation environment must meet EN50272-2001 requirements.
The ambient temperature of the battery must be stable. Ambient temperature is a major factor in determining the
battery capacity and life. The nominal operating temperature of battery is 20°C. Operating above this temperature will
reduce the battery life, and operation below this temperature will reduce the battery capacity. If the average operating
temperature of battery is increased from 20ºC to 30ºC, then the service life of the battery will be reduced by 50%. If
the operating temperature of the battery is above 40ºC, then the battery service life will be decreased in exponent
rate. In a normal installation, the battery temperature is maintained between 15°C and 25°C. Keep batteries away
from heat sources or air outlets.
If external batteries are to be used, the battery circuit breakers (or fuses) must be mounted as close as possible to
the batteries, and the connecting cables should be as short as possible.
1.3.3 Storing
Should the equipment not be installed immediately, it must be stored in a room so as to protect it Protection from
excessive humidity and heat sources (see Tab. 9-2).The battery needs to be stored in dry and cool place with good
ventilation. The most suitable storage temperature is 20 ºC to 25ºC.
Preventing battery deep discharge
Should the UPS remains unpowered for a prolonged period of time while the battery are connected, the batteryes may deeply
discharge and being so permanently damaged .In such cases it is therefore reccomented to leave the battery circuit breaker(s)
open. During storage in any case, periodically charge the battery according to the battery user manuals.
1.4 Positioning
When the equipment has been finally positioned, ensure the UPS will remain stationary and stable. To prolong the
service life, the choosen installation site must guarantee:
Space for easy operation on the UPS
Sufficient air to dispel the heat produced by the UPS
Protection from atmospheric agents
Protection from excessive humidity and heat sources
Protection against dust
Compliancy to the local fire prevention requirements
An operating environment temperature within +20°C to +25°C. The batteries are at maximum efficiency in this
temperature range (for information about the battery storage and transportation as well as the environment,
refer toTable 8-2 )

Chapter 1 Installation Of UPS Rack System 8
1.4.1 System Cabinet
A UPS system can comprise an UPS rack system, external battery cabinet, depending on the specific system
requirement.
All the UPS system cabinets used in the same installation site are of the same height and should be positioned
side-by-side to achieve an aesthetically appealing effect.
Refer to Chapter 7 Installation Drawing for the positioning of UPS cabinet.
1.4.2 Mooving The Cabinets
Warning
Ensure that any lifting equipment used in moving the UPS cabinet has sufficient lifting capacity.
The UPS is fitted with castors – take care to prevent movement when unbolting the equipment from its shipping pallet. Ensure
adequate personnel and lifting aids are available when removing the shipping pallet.
Ensure that the UPS weight is within the weight loading capacity range of any hoisting equipment. See Tab. 1-1 for
UPS weight.
UPS and optional cabinets can be handled by means of a fork lift or similar equipment. The UPS cabinet can also be
moved by its castors when moving in a short distance.
Note: Care must be taken when handling units fitted with batteries. Keep such moves to a minimum.
1.4.3 Transporting The Cabinets
Note :
The unit can be shipped whit 1, 2 or 3 power modules installed but not with 4 or 5 ( to be ship separate), and cannot
be with any battery modules installed
1.4.4 Clearances Required For Operating
As LIEBERT APM series UPS has no ventilation grills at either sides, no clearances are required for the sides.
To enable routine tightening of power terminations within the UPS, it is recommended that 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 350mm in the rear side of the rack to permit adequate circulation of air coming out of the unit.
If the UPS make use of internal modular battery sufficient clearing shall be given at the back site to allow personnel to
operate the battery circuit breakers (~ 600mm)
1.4.5 Front Access
The component layout of the UPS rack system supports front access and repairing the UPS, thus reducing the space
requirement for side and rear access.
1.4.6 Final Positioning
When the equipment has been finally positioned, ensure the adjustable feet are set so that the UPS will remain
stationary and stable.
1.4.7 Installation Of Adjustable Feet
Installation diagrams in Chapter 4 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 UPS is to be located on a raised floor, it should be mounted on a
pedestal suitably designed to accept the UPS point loading (more than 1000 kg). Refer to the bottom view in Fig. 4-7
to design this pedestal and stable.

Installation procedures of Battery Modules
When installing battery modules always work from the lower available space upwards to prevent raising the center of
gravity.
1. Open the front door
2. Insert the module in the installation position, and push it into the cabinet.
3. Secure the module to the cabinet trough the fixing holes on both side of the front panel of the module
1.4.10 Cable Entry
Cables can enter the LIEBERT APM series UPS rack system and battery cabinet from below. Cable entry is made
possible through a blanking plate fitted at the bottom of the equipment. The recommended installation practice is to
install glands to prevent foreign material or vermin entering the cabinet.

1.5 External Protective Devices
For safety concerns, it is necessary to install external circuit breakers or other protective devices for the input AC
supply of the UPS system. This section provides generic practical information for qualified installation engineers. The
installation engineers should have the knowledge of the regulatory wiring standards, and of the equipment to be
installed.
1.5.1 Rectifier And Bypass Input Supply Of The UPS
Over currents
Install suitable protective devices in the distribution unit of the incoming mains supply, considering the power cable
current-carrying capacity and overload capacity of the system (see Tab. 9-7).
Generally it is recommended a magnetic circuit breaker with IEC60947-2 tripping curve C (normal) rated at the 125%
of the current listed in Tab. 9-7.
Split bypass: In case a split bypass is used, separate protective devices should be installed for the rectifier input and
bypass input in the incoming mains distribution panel.
Note
The rectifier input and bypass input must use the same neutral line.
Note
For IT power network system, 4-pole protective device must be installed on the external input distribution and external output
distribution of the UPS.
Protection against earth faults (RCD devices):
The RCD device installed upstream of the input supply should be:
Sensitive to DC unidirectional pulses (class A) in the network
Insensitive to transient current pulses
Have an average sensitivity that is adjustable between 0.3A and 1A.
Fig. 1-3: The symbols of RCCB
When using the RCD in the split bypass system or parallel system, the RCD should be installed in the upstream of
the input distribution to avoid wrong alarm.
The residual current introduced by RFI filter in the UPS is between 3.5mA and 1000mA. It is recommended to confirm
the sensitivity of each RCD of upstream input distribution and downstream distribution (to load).
1.5.2 External Battery
The DC compatible circuit breaker provides over current protection for UPS system and battery, which is provided by
the external battery cabinet. See Appendix A for a selection guide

1.5.3 UPS Output
In the eventuality that an external distribution panel is used for load distribution, the selection of protective devices
must provide discrimination with those that are used at the input to the UPS (see Tab. 9-7).
1.6 Power Cables
Design the cables according to the descriptions in this section and local regulatory wiring standards, and the
environmental conditions (temperature and physical support media) should be taken into consideration. Refer to
IEC60950-1 Table 3B Cabling.

Tab. 1-3 Maximum steady state AC and DC Current
Note:
1. Input current of common input configurations of rectifier and bypass
2. Take special care when determining the size of the output and bypass neutral cable, as the current circulating on
the neutral cable may be greater than nominal current in the case of non-linear loads, which is usually 1.732 times of
rated currents..
3. Add 7 A per each redundant Power Module
The earth cable connecting the UPS to the main ground system must follow the most direct route possible. The earth
conductor should be sized according to the fault rating, cable lengths, type of protection, etc. According to
AS/IEC60950-1, the cross section area of the conductor is 80mm
2
(150kVA).
When sizing battery cables, a maximum volt drop of 4Vdc. is permissible at the current ratings given in Tab. 1-3. The
load equipment is connected to a distribution network of individually protected busbars fed by the UPS output rather
than connected directly to the UPS. In parallel multi-module systems, the output cable of each ups rack unit should
be kept at equal length between the output of the ups rack output terminals and the parallel distribution busbar to
avoid affecting the shared current. When laying the power cables, do not form coils, so as to avoid the formation of
electromagnetic interference.
See Chapter 4 Installation Drawing for the positions of wiring terminals.

maintenance bypass switch is opened. Attach necessary warning signs to these switches to prevent unauthorized
operation.
2. Open the doors of the UPS, remove the front protective cover and then the power connection buses are visible.
3. Connect the protective earth and any necessary grounding cables to the enclosure of the cabinet at the bottom
part of the UPS rack (close to the cabinet side where the output connection terminal strips are located).The cabinet
for the UPS must be connected to the user’s ground connection.
Note: The grounding cable and neutral cable must be connected in accordance with local and national codes
practice.
Referring to
Fig. 4-11 , Identify and make power connections for incoming cables according to one of the procedures below,
depending on the type of installation:
Common Input Connections
4. For common bypass and rectifier inputs, connect the AC input supply cables to the UPS input terminals
(mA-mB-mC-mN) ensuring correct phase rotation. Tighten M6 bolts to 5 Nm.
Split Bypass Connections
5. If a 'split-bypass' configuration is used, connect the AC input supply cables to the rectifier input terminals
(mA-mB-mC-mN) and the AC bypass supply cables to the bypass input terminals (bA-bB-bC-bN) ensuring correct
phase rotation. Tighten M6 bolts to 5 Nm
Note: For split Bypass operation ensure that the busbars between Bypass and Rectifier inputs are removed. The
neutral line of bypass input must be connected to that of the rectifier input.
Frequency Converter Mode
If the frequency converter configuration is used, connect the AC input cables to the rectifier input terminals
(mA-mB-mC-mN) ensuring correct phase rotation. Tighten M6 bolt to 5Nm, M8 bolt to13Nm and M10 bolt 26Nm.
No need to connect the bypass input cables to bypass input terminals (bA-bB-bC-bN).
Note: For the frequency converter operation mode, ensure that the busbars between Bypass and Rectifier inputs are
removed.
