CHAPTER 6

Battery Installation

6.1Introduction

The UPS battery consists of battery blocks connected in series to provide a nominal d.c. input voltage for the UPS inverter. The required ‘Autonomy time’ (the time that battery can maintain supply to the load in the event of a mains failure) is limited by the ampere hour size of the individual battery blocks and in some cases it could mean several strings are connected in parallel.

Usually, with UPS installations in the power range covered by the ‘Hipulse’ equipment, the batteries are contained in a purpose built battery cabinet which sits alongside the main UPS and the Battery Circuit Breaker Controller Board ( for all sizes).

The battery cabinet can be installed in one of the following forms:

Complete installation comprising the battery cabinet, batteries and the circuit breaker. Battery cabinets and battery circuit breaker - with no batteries.

Battery cabinet only – with no batteries or circuit breaker.

It is possible to install batteries of various types and capacity in the cabinet to obtain he required autonomy characteristics.

It must be possible to disconnect the battery from the UPS module when undertaking maintenance or service procedures. This is facilitated by means of a suitably rated circuit breaker which must be located as close as possible to the battery terminals, and the power and control cables connected to the UPS using the most direct route possible. The circuit breaker can be switched off manually ON or OFF, but should also contain an under voltage release mechanism (to be energized by the UPS control electronics) and a magnetic trip facility for overload protection which is used in conjunction with battery circuit breaker controller module.

If multiple sets of batteries connected in parallel are used to increase battery autonomy, the extension must be fitted with a sectioning device to permit work to be performed on one set of batteries wile the others remain in service.

For external battery assembly, a customized Battery Circuit Breaker (the features of which depend on the sizes of the UPS) including a Battery Circuit Controller Board (the same for all sizes) can be provided. This box is designed to be either wall mounted or assembled on a frame, and is connected between the UPS and the battery. Refer to section 6.9 for more information.

A common battery circuit breaker is available for systems incorporating two parallel UPS with a common battery. It comprises two switches, which may be used to section one UPS while the other remains active. Refer to section 8.3 for more information.

6.2Safety

Special care should be taken while working on batteries associated with Hi-pulse UPS system equipment. When all the cells are connected together, the battery terminal voltage will exceed 400 V DC and is potentially lethal. A primary safety consideration is to physically isolate the battery installation from all but appropriately qualified maintenance personnel, which is best achieved by locating in a key locatable cabinet or a purpose designed, dedicated battery room.
