Installing the Inverter/Charger
Step 3: Connecting the AC Input and AC Output Wires
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.
AC Wiring Compartment For your reference, the AC wiring
compartment is shown in Figure 6 on page 25.
AC Knockouts There are two dual 1.0" (Ø34.6mm) and 3/4"
(Ø28.3mm) trade-size knockouts on the side panel for AC wiring.
Use the same trade size of strain relief as the trade size of the
knockout(s) you are using.
AC Wiring Terminals The AC wiring terminals accept cables of
a specific size. See “AC Wiring” on page 11 for required sizes.
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.
