Procedure
1. Insert the positive and negative cables through the hole in the waterproof cover. (This cover has been
used in battery connection.)
2. Use a 3-mm wide-bladed screwdriver to strip the insulation layer around 8 to 10 mm length from one
end of each cable.
3. Insert the cable ends to the sleeves. Use a crimping plier to assembly the cable ends.
4. Insert the assembled cable ends into the blue positive and negative battery connectors. Gently pull the
cables backwards to ensure firm connection.
5. Tighten the lock screws on the positive and negative cable connectors.
6. Connect the positive and negative cable connectors into the positive and negative PV ports on the
inverter. After you hear a “click” sound, the cables are firmly connected.
7. Install the waterproof cover for PV and battery ports. Tighten the screws.
