switch signal, CAN-bus of charge& discharge), temperature sensor cables and current sensor cables
b)
Voltage collection cables connection, connect the voltage collection cables to cells orderly according
to the system diagram and labels. After confirming all cables connected with correct order(very
important), please connect the other side to module
c)
Insulation detection cables, high voltage detection cables connection (optional accessories), connect
the cables of insulation detection, high voltage detection and divider, and connect the other side after
confirm all cables connected correctly
d)
After all of the cables connected, please check each cable according to the system diagram to ensure
all cables connected correctly and reliably.
*Notice:
All connectors should be locked before connecting the detection cables
Check the insulation of connectors; avoid conductive impurity such as water, dust, or metal particles.
