AC connection:
1. Route the five wires (A, B, C, N, PE wires) through the AC protective cover; crimp the
ring or spade terminals; then connect them to the screw terminals on the AC connector.
2. Connect the AC cable to the corresponding AC terminal.

3.Secure the protective cover onto the inverter and tighten the screw on the protective
cover.

Residual current monitoring device (RCMU)
As the inverter is equipped with a highly accurate residual current detection device, it is
not recommended to install a leakage protection switch. If an external residual-current
device is required, install a Type-A leakage protection switch that trips at a residual
current of 300 mA or higher and install it between the inverter and the grid. When
multiple leakage protection switches are installed, do not connect them to a shared
neutral line. Otherwise, the leakage protection function may be triggered by mistake.
Recommended cable specifications:
6.3 DC side wiring
Ø The PV panel will generate voltage with solar irradiation. High voltages
may occur when the panels are connected in serials, which can result in
personal injury. Therefore, cover the panels with opaque materials before
connecting the DC input cable and ensure that the DC switch is off.
Ø To avoid electric shock, do not touch the live parts, and connect the
terminals carefully.
Ø Please make sure that the AC switch has been disconnected before
wiring.
