The wiring sequence is: first connect the OT terminal to the high-voltage box terminal, and then connect to the
battery modules. Please strictly follow the wiring sequence. Otherwise, it will be easy to short-circuit.
The self-locking connector's color should correspond to the battery module terminal's color: orange corresponds
to the positive pole, and black corresponds to the negative pole.
The bolt type on the high-voltage box terminal is M8, and the recommended tightening torque is 7 N.m.
4.6 Connecting Signal Cable
Context
Please pay attention to the direction when plugging the signal cable connector, do not operate violently.
Signal cables and power cables must be routed separately.
If there are multiple battery cabinets in parallel, there is a Host machine label on the master high-voltage
box and a Slave machine on the slave high-voltage box. Only the master high-voltage box needs to connect
the signal cable to the inverter. Please pay attention to the distinction.
Procedure
1 Connect the internal signal cable of the RESS battery cabinet.
