Safety Precautions

This manual contains information concerning the installation and operation of Modular UPS. Please carefully read this

manual prior to installation.

The Modular UPS cannot be put into operation until it is commissioned by engineers approved by the manufacturer (or

its agent). Not doing so could result in personnel safety risk, equipment malfunction and invalidation of warranty.

The UPS has been designed for commercial or industrial use only, and is not intended for use in any life support

application. This is a CLASS C Uninterruptible Power Supply (UPS) product. In a domestic environment, this product may

cause radio interference, in which case, the user may be required to take additional measures.

Conformity and standards

This product complies with CE73/23 & 93/68 (low voltage safety) and 89/336 (EMC), and the following UPS product

standards:

*IEC62040-1-1-General and safety requirements for use in operator access area

*IEC/EN62040-2 EMC requirements CLASS C

*IEC62040-3 Performance requirements and test methods

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 10kW 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: 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 contactor 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.

Safety Precautions

II Rack Modular UPS System 10-90kVA User 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

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. 1-phase 3-wires is also 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 contactor 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.
