7.5 Wiring Steps
A.
Battery power cable
Step 1
: Connect the power cable starting from the first battery module in series with other battery modules
(Orange opposite, black negative). A ‘click’ sound indicates the connections are secured. The positive and
negative connection of the battery cable is shown in below.
Step 2
:
Measure voltage value: After all battery modules are connected in series, use a multimeter to
measure the DC voltage on DC terminal. The total voltage should be N *52±10V (N is the total
number of battery module). Please refer to the picture below for voltage test.
B.
Communication cable connection:
Step 1
: Take the main positive cable (two orange plugs), the main negative line (two black plugs) to
connect the BMS BOX.
Step 2
: Then connect the 485 on the BMS BOX to the RS485-1 of the first battery module, connect
the RS485-1 of the previous battery module to RS485-2 of the next battery module, leave the last
module’ s RS485-2 vacant. Wiring shall be connected in the sequence as shown in below.
