DC Wiring
DC wiring is generally very simple, the
positive (+, may be red for identification) and
negative (-, may be black or yellow for
identification) cables from the inverter/charger
terminal posts are connected to the house or
auxiliary battery. Connection to the engine
starter battery is not recommended.
High current will pass through the DC
wiring. All wires must be properly sized and
all connections clean and tight. It is
recommended that the battery cable length
does not exceed 10 feet.
Battery cables should be connected to the
inverter/charger before any connections are
made to the battery. Follow the battery
hardware stackup diagram.
• Remove the negative (-) battery cable
cover from the unit and attach the battery
cable. Tighten the battery terminal bolts to a
torque value between 160 inch-pounds and
180 inch-pounds. Replace the cover for the
negative terminal before removing the cover for
the positive terminal.
INSTALLATION
Ground Fault Circult Interrupters
To conform to NEC regulations, certain
branch circuits must be equipped with a
Ground Fault Circuit Interrupter (GFCI). Please
consult the code or a qualified electrician for
details. Any such branch circuits must be
protected by a brand rated circuit breaker
consistent with the GFCI rating. Underwriters
Laboratories has tested the following GFCI,
and its use is recommended. Receptacle Type:
Pass & Seymour
Catalog Number 1591
Rated: 15 amps at 120 volts AC
Remote Control Wiring
If installing a remote panel, route the
remote cable and connect to the remote jack
on the front of the unit. Refer to the Freedom
Remote Control Panel or Link Owner’s Manual
for more information.
TSC Temperature Sensor
If installing the TSC (Temperature
Sensitive Charging) sensor, connect the ring
terminal end to the positive battery post,
complete the routing of the RJ11 cable (15 feet
supplied) and connect the plug end to the TSC
jack on the front of the unit.
Freedom Inverter/Chargers are not protected against DC reverse polarity. Be very careful to connect the
negative and positive cables correctly or damage will result and the warranty will be void.
