Step 1: Turn the DC switch to the “OFF” position. Remove the 8 cover screws, then remove the
cover.
Step 2: The conduit plugs (circled in blue) should be removed by the operator before
connecting the wires.
Step 3: Operator should use the standard size conduit which must fit the holes on the bottom
of the inverter. Conduit fittings must be watertight.

Step 4:
4.1 Choose the appropriate wire according to the specific connection.
4.2 Remove 0.47in/12mm of the insulation from the end of the DC wire (the AC wire
shall be removed by 0.71 in/18mm).
4.3 Insert the end of wires into the Cord End Terminal, and then use the crimping
pliers to crimp the Cord End Terminal tightly (the shape will be square).
4.4 Using the slot screwdriver to compress the orange button of the terminals,
insert the stripped wires into terminal and ensure that all conductor strands are
captured in the terminal.
4.5 Loosen the slot screwdriver.
