1. Before connecting DC input power cables, mark the polarities on the cables to ensure that the
cables are connected correctly. If the cables are connected incorrectly, the device may be
damaged.
2. Check that DC input power cables will not be disconnected by pulling them.
3. If DC input power cables are reversely connected and the DC switch is ON, do not turn off the
DC SWITCH immediately. Otherwise, the equipment may be damaged. You can disconnect the
DC input power cable on the PV string side or wait until the PV string voltage reduces to a value
within the safety range. Then, turn off the DC SWITCH, remove the positive and negative
connectors, and rectify the connection.

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.
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 2*2*1 network cable or a communications cable with a cross sectional area of
1 mm2and 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 the COM1 and COM2 connectors at the inverter
bottom.
4. Connect the input end to terminals 5 and 7 in the
terminal block and connect the output end to
terminals 6 and 8 in the terminal block.
6. Use a torque wrench to tighten the locking caps to a torque of 7.5 N·m.
To ensure good sealing, you are advised to apply firestop putty to the used waterproof cable
connectors at the bottom of the chassis.
