Pin Wiring

Wiring notes

• • 1) For good grounding, isolate pin 12 (power supply ground) and pin 7 and 5 (input / output / reference voltage ground)

• • 2) According to CAN communication application standards, cables use twisted pair or shielded twisted pair

• • 3) Ensure that the CAN Bus terminal resistance is configured

• • 4) Ensure that the wiring harness minimizes electromagnetic interference between signal cables

• • 5) Isolate the high-voltage AC cable and the DC signal and power cable

• • 6) Ensure that all cables are not short-connected and disconnected

• • 7) Ensure the safety of useless cables and pins, and do not short-connect them

• • 8) If there is a battery charging equipment during the installation, please isolate the controller

• • 9) Observe health and safety regulations during operation and protect site personnel

• • 10) Wiring operation after power-off
