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.
After battery connection, the battery terminals voltage will exceed 400Vdc and is potentially lethal.
Follow the suggested actions here below:
Eye protection must 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
Before installing UPS, please check these items as below:
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).
Improper use of UPS and in condition out of the operating range invalid the warranty.
Avoid to install the UPS in room which are exposed directly under sunlight or near sources of hot air.
