To prevent dust from collecting, connect each AC module one by one in the following order:

Step 1. Take the female connector out from the cable holder on the PV frame.

(Do not take the unused connector out of the last AC module to prevent sagging.)

Step 2. Remove the dust cover of the trunk female connector of the module you want to install and trunk male connector of next one.

Step 3. Insert the trunk female connector into the trunk male connector in the illustrated direction below until you hear a clicking sound to connect all AC modules of each array.

WARNING

Make sure to use only dedicated cable connectors provided by LG. Non-genuine connector may not be waterproof and/or non-genuine cable may limit the current flowing inside.

To prevent the danger of the electric shock, firmly connect all connectors and endcaps.
