NOTICE
The residual current device (RCD) should be connected to the load side.
For Australia safety regulation, the neutral cable of On-Grid side and Back-Up
side must be connected together; otherwise Back-Up function will not work.

7.5 Communication Connection

Communication connection port as follows:
Please follow the below steps for communication connection
1. Lead the communication cables through the cable glands of the AC&COM connection
cover, don' t tighten the pressure caps of the cable glands.

1) Connect the BMS port on the inverter and COM port on the battery with
communication cable.
2) For meter wiring, please read electricity meter wiring instructions of the meter.
3) If DRM support is specified, the system may only be used in conjunction with a
Demand Response Enabling Device (DRED). This ensures that the system implements
the commands from the grid operator for active power limitation at all times. The
system and the Demand Response Enabling Device (DRED) must be connected in the
same network.
4) Take out 10 pin terminal block for AUX connection.
For AUX position definition, please refer to the relative wiring document.
2. Place the AC&COM connection cover against the inverter housing and tighten them.

7.6 PV Connection

Please ensure the follows before connecting PV strings to the inverter:
Make sure the open voltage of the PV string will not exceed the max. DC input
voltage (1000Vdc). Violating this condition will void the warranty.
Make sure the polarity of the PV connectors is correct.
Make sure the PV-switch, breakers of battery, AC-BACKUP and AC-Grid are all in their
off-states.
Make sure the PV resistance to ground is higher than 200KOhms.
The inverter uses the MC4 PV connectors. Please follow the picture below to assemble
the MC4 connectors. PV cable cross section requirements: 4~6mm2.
