Battery installation
3.7.1
Fitting & connecting the batteries
The following notes, in conjunction with the diagrams, illustrate the broad principles to be followed when fitting and
connecting the majority of battery installations.
3.7.2
Fitting the batteries
1. In general a minimum space of 10 mm must be left on all vertical sides of the battery block to permit free air
movement around the cells.
2. Clearance should be allowed between the top of the cells and the underside of the shelf above (this is necessary
for monitoring and servicing the cells).
3. When installing the batteries on racks always work from the bottom shelf upwards to prevent raising the centre
of gravity.
3.7.3
Connecting the battery
1. When the battery circuit breaker cabinet is installed on a raised floor the battery power cables and circuit
breaker control cables can be routed to the UPS cabinet via the floor of the cabinet. If the UPS and battery
circuit breaker cabinet are located adjacent to each other and located on a solid floor these cables can be passed
between the cabinets via the lifting apertures located in the lower sides of the cabinets.
2. In general it is recommended that the inter-connecting cables are fitted to the batteries within their particular
level before fitting the inter-level connecting cables, followed finally by the cables to the circuit breaker.
3. An insulating shroud should be fitted to each terminal after its connection has been made.
4. When connecting the cables between the battery extremities to the circuit breaker always connect the circuit
breaker end of the cable first.
3.7.4
Battery room design
Whatever the type of mounting system selected, the following conditions should be noted:
Layout of 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 cables must be used for connections.
Service platform:
The service platform (or duckboard) must be slip-proof, insulated from the floor and be at least one metre wide.
Connections:
All connections must be as short as possible.
Battery protection circuit breaker:
The battery circuit breaker is generally installed at the front of the battery room. The connection of Circuit Breaker Box
available for the 'Hipulse' is described in the following paragraph.
