Do not connect incoming AC from any
source to the AC output of the inverter
/
charger. This is known as backfeeding
and will damage the unit and void the
warranty. The Over Temp/Overload and
Low Battery LEDs will be blinking rapidly if
this condition exists.
WARNING
Grounding
For safety purposes, the chassis of the inverter
/
charger must be connected to your AC ground
system. Use 8 AWG bare copper or green
insulated wire, strip one end and use a screw-
driver to secure it to the chassis ground bonding
lug on the side of the unit. This wire will connect
to the ground in your AC electrical system.
Make sure the connection is clean and tight.
The system AC ground bonding terminal is
located on the front of the unit under the
wiring cover at the bottom of the unit. This
connector is for the bare copper or green
ground wires from the AC branch circuit supply
and to the AC loads or distribution panel. It is
important that these AC input and AC output
ground wires connect to the AC ground bus in
the circuit breaker panels.
Some installations require heavier grounding
wire. Conform to local and national electrical
codes.
More information on grounding can be found
in the National Electrical Code and local
electrical codes.
INSTALLATION
Note: The battery cables are not connected
to the AC ground strip or to the chassis lug
of the unit.
Neutral Bonding
For safety purposes and NEC code
requirements, the FP3000-12 unit internally
bonds the AC output neutral (white) to the AC
output ground (green), when the unit is OFF or
in the inverter mode. When incoming AC
power is applied and the transfer switch is
engaged, the internal neutral-to-ground bond is
automatically lifted.
When external AC power is applied, the
grounding system is connected to the source
power ground, where neutral and earth ground
are bonded together. This technique ensures
safety in all conditions and conforms to the
requirements of the NEC.
