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 Remote Control
Panel 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.
The FP3000-12 is 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.
