1.1 Introduction
WARNING
Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer.

electrical installation.
WARNING
Battery hazards
Special care should be taken when working with the batteries associated with this equipment. When connected
together, the battery terminal voltage will exceed 400 VDC 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.
For more details, see Chapter 3 ‘Battery Installation’
Note
The UPS System can also be connected to an IT (isolated neutral) power system.
This section describes the UPS system's environmental requirements and mechanical considerations that must be taken
into account when planning the positioning and cabling of the UPS equipment.
Because every site has its peculiarities, it is not the aim of this chapter to provide step-by-step
installation instructions, but to act as a guide as to the general procedures and practices that
should be observed by the installing engineer.
