ATTENTION!!!
Remove the battery fuses before making the connection of the battery circuit
breaker during the battery installation. (Turn off into “0” (OFF) position)
5)
Connect the copper earth bus, which is under the safety earth and the cables power connection.
Note:
The earth and the neutral connections must be done according to national rules.
If the REMOTE STOP option is going to be used, you should connect the remote stop button
(normally open), to the pins 4 and 5 of the remote stop connector (CN3) on the PCB ITF3.
3.4.3 Battery
Installation
ATTENTION!!!
Remove the battery fuse before making the connection of the battery circuit
breaker box during the battery installation.
The batteries of 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 positioned 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.
2.
Please check the battery connecting materials.
3.
Please put 8 pieces of the batteries to each rack.
4.
Start installing 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 3-3
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 3-3
7.
Please pay attention to the connections and the poles’s directions between the racks.
