4.4.4 Battery Installation
WARNING!!! Becareful while connecting batteries.
ATTENTION!!!
Remove the battery fuse before making the connection of the battery circuit breaker box dur-
ing 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 manufac-
turer’s recommendations. In general, batteries require a well-ventilated, clean and dry environment at reason-
able 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 clear-
ance 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.
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 suitable number of batteries at each rack.
4. Start locating the batteries from top to the bottom on the racks.
5. Becarefull about the connection between the racks and polarities.
6. After interconneting the batteries, connect the (+) and (-) poles to the battery input terminals on the UPS.
Be careful to connect the batteries correctly and do not turn on (F1) before checking all connections and
turn F1 on only after starting the UPS.
