6.1 Overview Of All Electrical Wirings Method
All electrical wiring will be done in the wiring box, and all electrical wiring
methods are similar. Therefore this section will introduce all electrical
wiring steps and requirements.

A1-Hybrid series inverter has 9 1G holes and 2 3/4G holes for wiring connection.
The 9 1G holes are used for electrical wiring connection, 2 3/4G holes are used for
communication connection.
9 1G waterproof plugs and 2 3/4G waterproof plugs has been installed on inverter
at the factory.
Before wiring connection, these waterproof plugs should be removed by the
operator.
Step 1: Remove the waterproof plugs by placing a flat blade screwdriver in the slot
on the waterproof plug face and turning while gripping the nut on the inside of the
enclosure to ensure it does not slip.
Step 2: Unscrew the nut from the waterproof plug and slip the conduit plug out of
the waterproof opening.

Operator should use the standard size conduits and plugs which must fit with the
holes on the bottom of the inverter. Conduit fittings need to be water tight, and
an insulated type is preferred.
Once conduit and fittings are installed, wires should go through the conduit and
be locked into the corresponding terminals (refer to next section for details).
