Installing the Inverter/Charger
This guide for use by qualified installers only.
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 26.
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 12 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.
