Product Usage Instructions

Notes and Safety:

• Cut off all power of the inverter before installation.
• Wait for 5 minutes after power off.
• Danger of high voltage. Danger to life due to high voltage of this machine.
• Only authorized personnel is allowed to set the connection.

Wiring Connection:
Step 1: RS485 Terminal Connection

1. Prepare a communication cable.
2. Trip the insulation from the communication cable.
3. Connect the meter communication cable and inverter with reference to the inverter manual.
4. Connect the other end of the communication cable to the port 24 and 25 of the meter.

Please note that the same color communication cable is used for the same communication port identifier between the inverter and the meter. The color of the communication cable in the figure is for reference only. Please refer to the actual situation for the specific connection.

Step 2: Voltage Wire Connection

1. Connect the L wires with ports 2/5/8 of the meter.
2. Connect the N wire with port 10 of the meter.
3. Connect the L wires with CTs and insert the CT wires to ports 1/3/4/6/7/9 of the meter respectively.

Please follow the wiring diagrams provided in the user manual for accurate connections.
