*IEC/EN62040-2 EMC requirements CLASS A

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 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.

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.

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.

Chapter 1 Installation Of UPS Rack System 6

Warning: installation can only be done by authorized engineers

Note: 3-Phase 4-Wire Input Power is required

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

WARNING: battery hazards

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).

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.

Chapter 2 Battery installation 7

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.

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 )

Preventing battery deep discharge

LIEBERT APM UPS Module And Parallel System 30kVA~150kVA User Manual

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

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.

Warning

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.

The rectifier input and bypass input must use the same neutral line.

Chapter 1 Installation Of UPS Rack System 12

Note

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

power

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.

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

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 80mm2 (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.

3.2.3 Power Cables

The power cable connection of the parallel system is similar to that of the single UPS rack system. If the bypass input
and rectifier input share the same neutral terminal and if an RCD protective device is installed at the input, then the
RCD device must be installed before the input cables are connected to the neutral terminal.

Note: The length and specification of the power cables of each UPS module should be the same, including the
bypass input cables and UPS output cables, so that the load sharing effect can be achieved in bypass mode.

3.2.4 Control Cables

Refer to Chapter 1 1.7

Parallel control cable

The parallel control cable has THREE types in terms of length: 5m, 10m, and 15m. All the parallel cables are
designed to be shielded and double insulated, and are intended to be connected between the UPS racks to form a
loop as shown below. The parallel signal board X2 is installed at the front of the static switch power module. This

close loop connection ensures the reliability of the parallel system control. Refer to Fig. 3-2 and to Fig. 3-3

The power cable connection of the parallel system is similar to that of the UPS module system. If the bypass input
and rectifier input share the same neutral terminal, and if an RCD protective device is installed at the input, then the

RCD device must be installed before the input cables are connected to the neutral terminal. Refer to Chapter 1

According to the selected configuration, the LIEBERT APM can house from none to 9 battery modules connected in
parallel.

Each Modular Battery Cabinet can house additional 10 modules of battery

Each module is made of 3 battery boxes and a battery tray. Each battery box contains ten 9AH/12V batteries and
each battery tray has one 50A DC current limiting circuit breaker. The maximum discharging current of each layer of
battery is 45A. Over charging current will trip the circuit breaker and the monitoring unit will display the alarm.

Note

When using modular battery it is important to install at least 2 battery module per each power module installed.Not doing that will
result in the CB tripping before the battery reaches the EOD.

5.1 Introduction

The LIEBERT APM UPS provides the critical load (such as communication and data processing equipment) with high
quality uninterruptible AC power. The power from the LIEBERT APM UPS is free from voltage and frequency
variations and disturbances (interruption and spike) experienced at the Mains AC input supply.

This is achieved through high frequency double conversion power pulse width modulation (PWM) associated with full
digital signal processing control (DSP), which features high reliability and convenience for use.

As shown in Fig. 5-1, the AC input mains source is supplied at UPS input and converted into a DC source. This DC

source feeds the Inverter that converts the DC source into a clean and input independent AC source. The battery
powers the load through the inverter in case of an AC input mains power failure. The utility source can also power the
load through the static bypass.

When the UPS needs maintenance or repair, the load can be transferred to maintenance bypass without interruption
and the power module and bypass module can be removed for maintenance.

5.1.1 Split-Bypass Input

Fig. 5-1 illustrates the Liebert APM in what is known as the split-bypass configuration, i.e. the bypass uses a

separate AC source. In this configuration, the static bypass and maintenance bypass share the same independent
bypass power supply and connect to the power supply through a separate switch. Where a separate power source is
not available, the bypass and rectifier input supply connections are linked : the dotted lines represents the link

between

There is one manual bypass (maintenance bypass) for entire UPS Rack System.

mA-mB-mC-mN and bA-bB-bC-bN (see fig

5.1.2 Static Transfer Switch

The circuit blocks labeled Static Switch in Fig. 4-1 contain electronically controlled switching circuits that enable the

critical load to be connected to either 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; but in the event of a UPS overload or inverter
failure, the load is automatically transferred to the static bypass line.

To provide a clean (seamless) load transfer between the inverter output and static bypass line, the inverter output and
bypass supply must be fully synchronized during normal operating conditions. This is achieved through the inverter
control electronics, which makes the inverter frequency track that of the static bypass supply, provided that the
bypass remains within an acceptable frequency window.

A manually controlled maintenance bypass supply is incorporated into the UPS design. It enables the critical load to
be powered from the utility (bypass) supply while the UPS is shut down for routine maintenance.

Fig. 4-10

). The unit is shipped with the links installed

When the UPS is operating in bypass mode or on maintenance bypass, the connected electrical load is not protected from
power failures or surges and sags.

5.2 1+N Parallel System

Several “single unit” UPS Rack Systems may constitute a “1+N” system, where up to four single units operate
together for the purpose of providing additional power or reliability or both. The load is equally shared between any
paralleled UPSs.

In addition, 1+N groups may be configured as “distributed redundant” systems. Each UPS Rack System has
independent outputs that nevertheless are synchronized through a Load Bus Synchronizer (LBS) so that critical loads
can be seamlessly transferred from one UPS Rack System or Parallel System to another.

See 4.3 Operating Mode for more information.

5.2.1 Features Of Parallel System

1. The hardware and firmware of single UPS Rack System units is completely compatible with the requirements of a
parallel system. Parallel configuration can be achieved merely through settings in configuration software and
connecting the parallel control signal cables. The parameters settings for the UPS Rack Systems in parallel system
shall be consistent. .

2. Parallel control cables are connected in a ring, providing both performance and redundancy. Dual-bus control
cables are connected between any two UPS modules of each bus. The intelligent paralleling logic provides the user
with maximum flexibility. For example, shutting down or starting up UPS modules in a parallel system can be done in
any sequence. Transfers between Normal and Bypass modes of operation are synchronized and self–recovering e.g.
following overloads and their clearance.

3. The total load of the parallel system can be queried from each module’s LCD.

Note

5.2.2 Parallel Requirements Of UPS Rack Systems

Required

A group of paralleled UPS Rack Systems behave as if it were one large UPS with the advantage of presenting higher
reliability and/or higher total output power.

The following requirements apply:

1. All UPS Rack Systems must be connected to the same bypass source (i.e: must be in phase and have the same
neutral reference)

2. The bypass and the main input sources of each UPD rack unit must be referenced to the same neutral potential.

3. Any RCD (Residual Current detecting device), if installed, must be of an appropriate setting and located upstream

of the common neutral bonding point. Alternatively, the device must monitor the protective earth currents of the
system. Refer to the High Leakage Current Warning in the first part of this manual.

4. The outputs of all UPS Rack Systems must be connected to a common output bus.

5. The maximum recommended unbalance between the numbers of power modules in different racks is 3/5.

In order to comply to the above points even in a faulty condition, the following upgrade sequence is proposed.

5.3 Operating Mode

The LIEBERT APM UPS is an on-line, double-conversion, reverse-transfer UPS that permits operation in these
modes:

 Normal mode

 Battery Mode

 Auto-restart mode

 Bypass mode

 Black start mode

 Maintenance mode (manual bypass)

 Parallel redundancy mode

 Sleep Mode

5.3.1 Normal Mode

The UPS inverter power modules continuously supplies the critical AC load. The rectifier/charger derives power from
the AC mains input source and supplies DC power to the inverter while simultaneously FLOAT or BOOST charging its
associated backup battery.

Note

5.3.2 Battery Mode

Upon failure of the AC mains input power; the inverter power modules, which obtains power from the battery, supplies
the critical AC load. There is no interruption in power to the critical load upon failure. After restoration of the AC mains
input power, the “Normal Mode” operation will continue automatically without the necessity of user intervention.

5.3.3 Auto-Restart Mode

The battery may become exhausted following an extended AC mains failure. The inverter shuts down when the
battery reaches the End of Discharge voltage (EOD). The UPS may be programmed to “Auto Recovery after EOD”
after a delay time if the AC mains recovers. This mode and any delay time are programmed by the commissioning
engineer.

5.3.4 Bypass Mode

If the inverter overload capacity is exceeded under normal mode, or if the inverter becomes unavailable for any
reason, the static transfer switch will perform a transfer of the load from the inverter to the bypass source, with no
interruption in power to the critical AC load. If the inverter is asynchronous with the bypass, the static switch will
perform a transfer of the load from the inverter to the bypass with interruption in power to load. This is to avoid large
cross currents due to the paralleling of unsynchronized AC sources. This interruption is programmable but typically
set to be less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms (60Hz).

5.3.5 Black Start Mode

If the there is no utility input and you want that UPS passes from the OFF mode to the Battery Mode you have to
push the button in front of any one of the UPS Rack module, and then push “Inverter On ” button to start the inverter.

5.3.6 Maintenance Mode (Manual Bypass)

A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS becomes
unavailable e.g. during a maintenance procedure. This manual bypass switch is fitted in all UPS Rack System and
rated for full load of one UPS Rack

Chapter 4 Operations 41

5.3.7 Parallel Redundancy Mode (System Expansion)

For higher capacity or higher reliability or both, the outputs of several UPS modules can be programmed for direct
parallel: a built-in parallel controller in each UPS ensures automatic load sharing. A parallel system can be composed
of up to four UPS Rack Systems.

5.3.1 Sleep Mode

To improve system efficiency, when system capacity is high and the load is light you can decide to automatically shut
down a number of power modules according to load level: if then the load increases, dormant modules are
automatically started

To ensure that each module has equal chances of being selected as dormant and of dormancy duration, and that the
life cycle of each module is consistent, the polling dormancy policy is adopted for the modules. The dormancy
duration of each module can be set from 1 to 1000 days. When the dormancy duration of a module is reached, the
module automatically starts, and the next module enters into the sleep mode.

If a system is configured to have X redundant power modules, the number of dormant modules is such that in any
case, X module more than the ones required to sustain the load are not dormant .

It takes about one minute for the rectifiers and inverters of the dormant modules to start and share the load. During
this period, the system may be overloaded and switch to bypass mode, so it is recommended to enable the sleep
mode just when it is known that load changes slowly (e.g. by system upgrade) and not dramatically (e.g. by sudden
changes of workload). Two dormancy parameters are available at the background: Intelligent UPS Dormancy
Function and Module Dormancy Time.

Prerequisites for Enabling the Sleep Mode

To enter into sleep mode, the following prerequisites must be met:

The function of monitoring and setting dormancy is enabled.

The rectifier runs on the main channel without faults. The battery is almost fully charged.

The inverter does not report any fault or alarm.

The power supply for the bypass is available. The bypass voltage and SCR are normal.

It is adjustable between 3 and 60 minutes. The default is 5 minutes.

5.4.2 Advanced Functions (Software Settings Performed By The Commissioning Engineer)

Battery self-test and self-service

At periodic intervals, 20% of the rated capacity of the battery will be discharged automatically, and the actual load
must exceed 20% of the rated UPS (kVA) capacity. If the load is less than 20%, auto-discharge cannot be executed.
The periodic interval can be set from 30 to 360 days. The battery self-test can be disabled.

Conditions: Battery at float charge for at least 5 hours, load equal to 20~100% of rated UPS capacity

Trigger—Manually through the command of Battery Maintenance Test in LCD panel or automatically

Battery self-test interval: 30~360 days (default setting is 60 days)

5.5 Battery Protection (Settings By Commissioning Engineer)

Battery Low Pre-warning

The battery undervoltage pre-warning occurs before the end of discharge. After this pre-warning, the battery should
have the capacity for 3 remaining minutes discharging with full load. The time is user configured from 3 to 60 minutes.

6.4 Procedure For Switching The UPS Into A Maintenance Bypass From

Normal Mode

This procedure can transfer the load from the UPS inverter output to the maintenance bypass supply, but the
precondition is that the UPS is in normal mode before the transfer.

Caution

Before making this operation, read messages on display to be sure that bypass supply is regular and the inverter is synchronous
with it, so as not to risk a short interruption in powering the load.

1. Press the INVERTER OFF switch on the right side of the operator control panel for longer than two seconds (if
system is a interrupt transfer, there is a prompt to alarm and you must confirm the interrupt transfer). The UPS Mimic
indicator Inverter ON will extinguish and also the Status Indicator (6) will turn amber and will be accompanied by an
audible alarm. The load transfers to static bypass, and the inverter shuts down.

Note

Pressing the Alarm Silence ON/OFF button cancels the audible alarm but leaves the warning message displayed until the alarm
condition is rectified.

2. Open the UPS door, close the maintenance bypass switch on the right bottom of the unit from OFF to ON position.
The load power supply is provided by the manual maintenance bypass.

Warning

If you need to maintain the module, wait for 10 minutes to let the DC bus capacitor fully discharge before removing corresponding
module.
When the maintenance bypass switch is on position of ON, some part of the UPS circuit still has hazardous voltage. Therefore,
only qualified person can maintain the UPS.

Caution

When the UPS is in maintenance bypass mode, the load is not protected against abnormal mains supply.

6.5 Procedure For Completely Powering Down A UPS

If you need to power down the UPS completely, follow the procedures in section 6.3 to transfer the UPS from normal
mode to maintenance bypass mode.

If you need to isolate the UPS from the AC power supply, you should open the external input power supply isolation
first (if the rectifier and bypass use different power supply, you need to open these two input isolation respectively).

Warning

Shut down the maintenance power supply to avoid human injury.

6.6 EPO Procedure

The EPO button is designed to switch off the UPS in emergency conditions (e.g., fire, flood, etc.).To achieve this, just
press the EPO button, and the system will turn off the rectifier, inverter and stop powering the load immediately
(including the inverter and bypass), and the battery stops charging or discharging.

If the input utility is present, the UPS control circuit will remain active; however, the output will be turned off. To
completely isolate the UPS, you need to open the external mains input supply to the UPS rack.

6.7 Auto Start

Commonly, the UPS rack is start up on static bypass. When the mains power fails, the UPS draws power from the
battery system to supply the load until the battery voltage reaches the end of discharge (EOD) voltage, and the UPS
will shut down.

The UPS will automatically restart and enable output power:

 After the mains power is restored

 If the Auto Recovery after EOD Enabling feature is enabled

 After auto start delay (default setting is 10 minutes), The UPS charges the battery during the auto restart delay

to avoid the power failure risk to the load due to the second time of mains power failure

If the auto start function is not set in the UPS, the user can press Fault Clear to manually start the UPS.

6.8 UPS Reset Procedure

After using EPO to shut down the UPS, or after the UPS is shut down due to inverter over temperature, or overload,
or battery over voltage or too many switching times (BYP: XFER COUNT BLOCK), and after clearing all the faults
according to the prompt information displayed in screen, carry out this procedure to restore the UPS to normal
operation.

After confirming that the fault is cleared, perform the following procedures:

1. Press FAULT CLEAR to reset the EPO status.

2. Press INVERTER ON button on the right side of the operator and control panel for longer than 2s.

Chapter 5 Operating Instructions 47

The rectifier will be turned on automatically when the overtemprature fault disappears at 5 minutes after the disappearance of
overtemprature signals.

After pressing the EPO button, if the UPS mains input has been disconnected, the UPS is completely powered down.
When the mains input is restored, the EPO condition will be cleared and the UPS system will enable static bypass
mode to restore the output.

If the maintenance bypass isolatingswitch is put to ON and the UPS has mains input, then the UPS output is emergised.

The UPS module needs 10 minutes to discharge to safe voltage, do not operate on the UPS during this time.

6.9 UPS Power Walk in feature

The UPS rack units has so called “Power walk-in” function to control power modules from battery to mains one by
one to decrease load impact on generator. The rectifiers of modules start one by one in programmable time duration.
This time duration is programmable via Paramset from 5 to 30 seconds. There is also Power walk-in delay timer,
which delay start of Power walk-in function from 1 to 5 second. This feature is appreciated especially in parallel

clear the alarm.

2. Check if the bypass voltage waveform is normal. If the bypass voltage waveform has severe
distortion, please ask the user to confirm this and find a solution

The temperature of the inverter heat sink is too high to keep inverter running.This alarm is triggered
by the signal from the temperature monitoring device mounted on the inverter heatsink.The UPS
recovers automatically after the over temperature signal disappears and after 5 minutes delay.
If over temperature exists, check:

1. Whether the ambient temperature is too high.

2. Whether the ventilation channel is blocked.

3. Whether fan fault happens

4. Whether inverter overload time is out

measure the actual output current to confirm if the displayed value is correct.
Disconnect non-critical load.In parallel system, this alarm will be triggered if the load is severely
imbalanced

The UPS overload status continues and the overload times out.
Note:

1.

The highest loaded phase will indicate overload timing-out first.

2. When the timer is active, then the alarm “unit over load” should also be active as the load is above
nominal.

3. When the time has expired, the inverter Static Switch is opened and the load transferred to bypass.
The inverter shuts down and will restart after 10 seconds.

4. If the load decreases to lower than 95%, after 5 minutes, the system will transfer back to inverter
mode.Check the load (%) displayed in LCD so as to confirm if this alarm is true.If LCD displays that
overload happens, then check the actual load and confirm if the UPS has over load before alarm
happens

Bypass Phase Rotation is Reversed.Under normal condition, Phase B lags behind phase A by 120
degree and phase C lags behind phase B by 120 degrees.
Check if the bypass input phase rotation is correct.Correct the wrong phase rotation
