Step 3: Connecting the AC Input and
AC Output Wires
DANGER
FIRE, ELECTRICAL SHOCK, AND ENERGY HAZARDS
Make sure wiring being connected to the inverter/charger is de-
energized by a breaker or switch upstream. Lockout/Tagout is a
recommended practice by many electrical contractors. Always
lockout and tag disconnect devices before making connections. All
wiring must be done in accordance with local and national
electrical wiring codes.
Failure to follow these instructions will result in death or serious
injury

General AC Wiring Considerations
AC and DC
Wiring
Separation
Do not mix AC and DC wiring in the same
conduit or panel. Consult the applicable
installation code for details about DC wiring and
AC wiring in vicinity to each other.
AC Input and
Output
Isolation
The AC input and output circuits of this
inverter/charger are isolated from each other
when in invert mode to ensure safe operation.
This isolation must be maintained in the
installation, by being sure not to connect AC
input and output wiring to a common point. For
example, do not route the AC input and output
neutrals to a common neutral bus. It is highly
recommended to use a separate inverter load
panel to distribute power to inverter loads. All
wiring to this panel must be through the
inverter/charger and none to the main panel
upstream of the inverter/charger.
IMPORTANT
: wiring the output inverter to back
to the main panel could result in ground bonding
to occur in multiple locations in contravention of
applicable wiring codes and may result in
nuisance tripping of Ground fault protection
equipment. All wiring must be performed by a
qualified electrician.
