To make a hardwire connection with the AC OUTPUT of the inverter follow
this procedure:
1.
Ensure AC and DC power are OFF
2.
Install required circuit breaker to the AC load wiring system.
3.
Remove the knockout from the sidewall. Do not run the AC input and output wirings
through the same knockout.
4.
Locate the terminal blocks. The whole area will be labeled “AC OUTPUT” and there will
be three terminations:
(GND)
(L)
(N)
5.
Strip enough of the input cable jacket as to expose the three wires, about 2 inches
(50mm).
6.
Strip approximately 3/8 inches (10mm) of insulation from each wire. The terminal blocks
will accept wire sizes up to 10AWG.
7.
Feed the AC output cable into the knockout hole. Facing the front panel of the inverter
this should be on the right, and the label should read “AC OUTPUT.”
8.
Using a screwdriver, loosen the terminal screws.
9.
Fasten the ground (GND) wire first.
CAUTION
: Reverse polarity -
Connecting wires improperly (i.e. the
neutral
wire into the
line
termination) will cause the inverter to break down and possibly cause permanent damage.
10.
It is very important to not confuse the connections (i.e. putting the line conductor into the
neutral termination). From the AC cable, typical wire-color schemes are as follows:
BARE COPPER or GREEN or GREEN/YELLOW insulation is GROUND wire
BLACK or BROWN insulation is the LINE wire
WHITE or BLUE insulation is the NEUTRAL wire
Confirm proper wires are in correct termination and tighten screws. Leave some wiring
slack inside the compartment.
11.
Connect the AC wires coming from the AC OUTPUT to the AC load panel.
Ensure the GFCI is in its proper location and install the front panel
back on to the inverter.
AC wiring WITH an Inverter Subpanel –
In this wiring configuration, the AC input to
the inverter comes from a main AC panel with its own input circuit breaker. The AC output is
then routed to a separate inverter subpanel with a dedicated circuit breaker attached.
IMPORTANT
:
It is important to note the generator must have its own neutral bonded to
ground. If the generator’s neutral is not bonded to ground, a bonding jumper must be
installed. The input AC panel and the inverter subpanel must not have a permanent neutral
to ground bond installed.
