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: back feeding protection
This system has a control signal available for use with an automatic device, externally located, to protect against back feeding
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: Isolate the UPS before working on the circuit of this UPS.
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 “IEC62040-1-1-General and safety requirements for use in operator access area 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.

Chapter 1 Installation
UPS Module and Parallel System 10KVA~200KVA User Manual 1
Chapter 1 Installation
1.1 Introduction
This chapter introduces the relevant requirements for positioning and cabling of the Modular UPS 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 UPS system can be connected to TN, TT 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.
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 Table.9-2).The Modular 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 Table.9-8: Normal mode (VFI SS 111 double-conversion UPS)

Chapter 1 Installation
2 UPS Module and Parallel System 10KVA~200KVA User Manual
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 against excessive humidity and heat
sources (see Table.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 batteries may deeply discharge
and being so permanently damaged .In such cases it is therefore recommended 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
place chosen must guarantee:
Space for easy operation on the UPS
Air sufficient enough to dispel heat produced by UPS
Against atmospheric agents
Against excessive humidity and heat sources
Against dust
With the current fire prevention requirements
The operating environment temperature is 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 to Table.9-2 )
This equipment is of steel frame structure wrapped by removable panels. The top and side panels are fixed by screws.
After opening the UPS rack door, the auxiliary connections for external low voltage interface and the maintenance bypass can
be accessed. The UPS rack has an operator and control panel located on its front door, which provides the basic operating status
and alarm information. Batteries are external. The UPS provides air inlet port in the front and the air exhaust port in the rear
part.
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 Moving 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
警告

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 Table.9-3 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 Clearances Required for Operating
As rack module 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
500mm 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
1.4.4 Front Access
The component layout of the UPS rack system supports front access and repairing the UPS, thus reducing the space requirement for
side access.
1.4.5 Final Positioning
When the equipment has been finally positioned, ensure the adjustable feet are set so that the UPS will remain stationary and stable.
1.4.6 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 800 kg).

1.4.8 Installing Power Modules and Battery Modules
The number and possible installation positions of the Power Modules and Battery Modules may vary according to the chosen factory
configuration. Thanks to the different mounting depth it’s not possible to install a power module instead of a battery module and vice
versa.
Please install the power modules and Battery modules from bottom to top, so as to avoid cabinet toppling due to high gravity center.
Installation procedures of power modules
When installing power modules always work from the lower available space upwards to prevent from raising the center of gravity. The
default setting from the bottom space upwards is NO.1 to NO.10 (10 modules cabinet), NO.1 to NO.6 (6 modules cabinet), or NO.1 to
NO.3 (3 modules cabinet or battery inside model).
Insert the module in the installation position, and push it into the cabinet.
Secure the module to the cabinet through the fixing holes on both sides of the front panel of the module.

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
1.4.9 Cable Entry
Cables can enter the module UPS rack system and battery cabinet both from bottom and top. Cable entry is made possible through a
blanking plate fitted at the bottom or top 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, the magnetic circuit breaker with IEC60947-2 tripping curve C
(normal) at the 125% of the current listed in Tab. 9-7 is recommended. 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.
Protection against earth faults (RCD devices):
The RCD device installed upstream of the input supply should:
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

Chapter 1 Installation
UPS Module and Parallel System 10KVA~200KVA User Manual 7
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.
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.

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. 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 95mm2 (200kVA), the cross section area of the conductor is
50mm2 (120KVA).
4. When sizing battery cables, a maximum volt drop of 4Vdc. is permissible at the current ratings given in Table.1-2. 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 busbars to avoid affecting the shared current. When laying the
power cables, do not form coils, so as to avoid the formation of electromagnetic interference.
5. See Chapter 4 Installation Drawing for the positions of wiring terminals.

The EPO is triggered when shorting pin 2 and 3 or opening pin 2 and 1 of J4.
If an external emergency stop facility is required, it is connected via the reserved terminals of J4. The external emergency stop facility
needs to use shielded cables to connect to the normally open/closed remote stop switch between these two pins. If this facility is not
used, then pin 3 and pin 4 of J4 must be open, or pin 1 and pin 2 of J4 must be shorted.
Note
1. The emergency stop action within the UPS will shut down the rectifier, inverter and static bypass. However, it does not
internally disconnect the mains input power supply. To disconnect ALL power to the UPS, open the upstream input circuit
breaker(s) when the EPO is activated.
2. Pin 1 and 2 of J4 have been shorted before the UPS is delivered.
3. All auxiliary cables must be double insulated twisted cables with cross sectional area of 0.5mm2 ~ 1.5mm2 for maximum
connection length between 25m and 50m.
1.7.4 Generator Input Dry Contact
J5 is the status interface for generator connection. Connect J5-2 with J5-1, it indicates that the generator has been connected with the
system. The interface diagram is shown in fig.1-7, and interface description is shown in table.1-5.
