3.9 Battery connection
The UPS adopts positive and negative double battery framework, total 32(optional 34/36/38/40) in series. A
neutral cable is retrieved from the joint between the cathode of the 16th (17th/18 th/19th/20 th) and the anode
of the 17th (18th/19 th/20th/21 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. The user can
choose the capacity and the numbers of the batteries according to their needs. The connection scheme is
shown below
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.
Factory setting is battery quantity---32pcs, battery capacity---12V40AH. When connecting 32/34/38/40
batteries, please re-set desired battery quantity and its capacity after UPS starts in AC mode. Charging current
will be adjusted automatically according to battery capacity selected. All related settings can be done through
LCD panel or monitoring software.
WARNING!
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, either.
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.
