Chapter 2 Mechanical Installation

This chapter briefly introduces the mechanical installation of the HIPULSE U UPS, including the notes, environmental considerations, mechanical considerations, preliminary checks and installation drawings.

2.1 Notes

Warning

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

Warning

The UPS equipment should be installed by a qualified engineer in accordance with the information contained in this chapter and all equipment not referred to this manual is shipped with details of its own mechanical and 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 400Vdc and is potentially lethal.

1.Eye protection should be worn to prevent injury from accidental electrical arcs.

2.Remove rings , watches and all metal objects.

3.Only use tools with insulated handles.

4.Wear rubber gloves.

5.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.

6.If electrolyte comes into contact with the skin the affected area should be washed immediately with water.

Warning

The UPS system can be connected to an isolated neutral (IT) power system.

This chapter describes the 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.

2.2 Environmental Considerations

2.2.1 UPS Location

The UPS module should be located in a cool, dry, clean-air environment with adequate ventilation to keep the ambient temperature within the specified operating range (see Table 8-2).

All models in the HIPULSE U UPS range are cooled with the aid of internal fans. Cooling air enters the module through ventilation grills located at various parts of the cabinet and exhausted through grills located in the cabinet roof. When the cabinet is located on a raised floor, and bottom cable entry is used, additional cooling air also enters the UPS through the floor void. If necessary, a system of extractor fans should be installed to aid cooling-air flow, and a suitable air filtration system used where the UPS is to operate in a dirty environment.

Note:

1.When batteries are cabinet-mounted adjacent to the UPS module, it is the battery which dictates the designed maximum ambient temperature, not the UPS.

2.Power losses from the system which may be used in an air conditioning system are intended for operation using the inverter, as in the ECO mode configuration they would be undersized.
