3.8 Battery connection
10-30KVA: The UPS adopts positive and negative double battery framework, totally 20pcs (optional
16/18) in series. A neutral cable is retrieved from the joint between the cathode of the 10
th
(8
th
/9
th
) and
the anode of the11
th
(9
th
/10
th
) of the batteries.
40KVA: The UPS adopts positive and negative double battery framework, totally 40pcs (optional
32/34/36) in series. A neutral cable is retrieved from the joint between the cathode of the 20
th
(17
th
/18
th
/19
th
) and the anode of the 21
th
(18
th
/19
th
/20
th
) of the batteries.
Then the neutral cable, the battery Positive and the battery negative are connected with the UPS
respectively. The battery sets between the Battery anode and the neutral are called positive batteries
and that between neutral and cathode are called negative ones.
External battery connections for long-run units:
10-15-20-30-60-100KVA
40-80-120-160KVA
Note:
The BAT+ of the UPS connect poles is connected to the anode of the positive battery, the BAT-N is
connected to the cathode of the positive battery and the anode of the negative battery, the BAT- is
connected to the cathode of the negative battery.
CAUTION!
Ensure correct polarity battery string series connection. I.e. inter-tier and inter block
connections are from (+) to (-) terminals.
Don’t mix batteries with different capacity or different brands, or even mix up new and old
batteries.
WARNING!
Ensure correct polarity of string end connections to the Battery Circuit Breaker and from the
Battery Circuit Breaker to the UPS terminals i.e. (+) to (+) / (-) to (-) but disconnect one or more
battery cell links in each tier. Do not reconnect these links and do not close the battery circuit
breaker unless authorized by the commissioning engineer.
