6.8Battery Installation

Whatever the type of mounting system selected, following conditions should be noted:

Layout of the cells:

Whatever battery mounting system is used, the batteries should be laid out in such a manner as to make simultaneous contact with two exposed live parts having a potential greater than 150V impossible. Where this is not possible, insulated terminal shields must be installed and insulated cable must be used for connection.

Service platform:

The service platform (or duckboard) must be slip-proof, insulated from the floor and be at least one meter wide.

Connections:

All connections must be as short as possible.

Battery Protection Circuit Breaker:

A battery circuit breaker is generally installed in an enclosure of the wall close to the battery installation. The connection of the circuit breaker box available for the Hi- pulse is described in the following paragraph.

6.9Battery circuit breaker:

The Battery circuit breaker is fitted inside the Input Transformer cubical along with its control board and is used to connect the battery to the UPS in installations where the batteries are not contained in the standard battery cabinet.

Usually the breaker is fitted as close as possible to the batteries. Figure 6-3 shows details of the power and control cable connections between the circuit breaker or battery cabinet and the UPS itself. Two methods of connecting the three pole battery circuit breaker are illustrated in figure 6-2. Method A shows the spare pole being used to divide the battery bank in half, thereby reducing the battery total voltage to half when the circuit breaker is open during servicing etc. Method B connects the spare pole in series with the positive connection, thereby providing two sets of contacts in the positive line as an added safety precaution.

When installing the battery cabinet remove the battery fuse In the UPS before making the battery circuit breaker power connections.
