5.7.7 Battery Installation
ATTENTION!!!
Remove the battery fuse before making the connection of the battery circuit breaker box
during the battery installation.
The batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet, which
sits alongside the main UPS equipment. Sealed, maintenance-free batteries are normally used in this type of
installations.
Where battery racks are used, they should be sited and assembled in accordance with the battery
manufacturer’s recommendations. In general, batteries require a well-ventilated, clean and dry environment at
reasonable temperatures to obtain efficient battery operation.
In general a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimum
clearance of 20 mm should be allowed between the cell surface and any walls. A clearance of minimum150 mm
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). All metal racks and cabinets must be earthed. All live cell connections must
be shrouded.
The batteries are connected to the UPS through a circuit breaker (optional), which is manually closed and
electronically tripped via the UPS control circuitry. If the batteries are cabinet-mounted this circuit breaker is
fitted within the cabinet; however, if the batteries are rack-mounted or otherwise located remote to the main
UPS cabinet then the battery circuit breaker must be mounted as near as possible to the batteries themselves,
and the power and control cables connected to the UPS using the most direct route possible.
1.
Unpack each battery and check its terminal voltage. If any battery has terminal voltage less than 10,5 V it
must be charged before continuing.
2.
Please check the battery connecting hardware.
3.
Please locate 8 pieces of the batteries to each rack.
4.
Start locating the batteries from top to the bottom on the racks.
5.
Connect the cable between the battery circuit breaker’s positive port (BAT+) first then battery tray (+) at the
left topside as in the figure 5-3
6.
Connect the cable between the battery circuit’s negative port (BAT-) first then battery tray (-) at the right
bottom side as in the figure 5-3
7.
Please pay attention to the connections and the poles’s directions between the racks.
8.
Connect the battery circuit breaker’s “UPS(+)
⇒
BATT(+)” and “UPS (-)
⇒
BATT(-)” Ports to the battery
group connection terminals at the UPS cabinet.
9.
Connect the shielded control cable between the UPS and the battery circuit breaker as in the following.
