Installing RS485 Communications Cables
2.5
1. When routing communications cables, ensure that communications cables are separated from
power cables and away from interfering source to prevent communication from being affected.
2. RS485 communications cables can be connected to the terminal block or RJ45 ports.
Connecting to the terminal block is recommended.
NOTICE
1. Remove an appropriate length of the insulation layer from the cable using a wire stripper.
Method 1: Connecting to the terminal block (recommended)
The DJYP2VP2-22 2x2x1 network cable or a communications cable with a cross sectional area of
1 mm
2
and external diameter of 14–18 mm is recommended.
2. Remove the locking caps from the COM1 and COM2 waterproof cable connectors at the inverter
bottom and remove the plugs from the locking caps.
3. Route the cables through the locking caps and then the COM1 (RS485 IN) and COM2 (RS485
OUT) connectors at the inverter bottom.
