2.7 Battery Installation
WARNING!!! Be careful while connecting batteries.
ATTENTION!!!
Open the battery switch/fuse before making any connection on the batteries.
The batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet.
In DS300SHPA Series 10-15 and 20 KVA UPSs, there is enough space for 60 pieces of 12V 5-7-9Ah
maintenance free batteries.
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. All metal racks and cabinets
must be earthed.
1. Unpack each battery and check its terminal voltage with a suitable load. Any battery with terminal
voltage less than 10,5V must be charged before installation.
2. Please check the battery connecting hardware and documents. (cables, trays, connection diagrams)
3. Please locate suitable number of batteries on each rack, according to the battery installation and
connection diagram given with the unit.
4. Start locating the batteries from top to the bottom on the racks.
5. Be careful about the connection between the racks and polarities.
6. After interconnecting the batteries, connect “+”, “0” and “-“ leads of the batteries to the battery input
terminals on the UPS. Be careful to connect the batteries correctly and do not turn on (S5) before
checking all connections and before starting the UPS. In DS300SHPA Series UPS, 60 blocks of
batteries are connected in series, in such a way that they form two strings of batteries with opposite
polarity; with a center tap connection to the NEUTRAL (N1-N2) internally.
NOTE THAT SEPARATE CABLES FROM EACH BATTERY GROUP SHOULD BE CONNECTED TO K2
TERMINALS TO FORM THE MIDPOINT CONNECTION.
WARNING!!! NEVER TURN ON S5 (BATTERY FUSE) WITHOUT CENTER POINT CONNECTION TO K2.
