If the circuit breaker immediately trips, the
electrical distribution system has a short or
the circuit breaker is faulty. Call a qualified
electrician. If the circuit breaker does not trip,
reconnect a combination of loads that will
not overload the generator or cause the circuit
breaker to trip again. Remember to compensate
for elevation and temperature changes when
reconnecting loads.
NOTE
An appliance or load may have a short if
it causes a circuit breaker to trip after
reconnection. DO NOT continue to reset
breaker. Have the problem corrected
before resuming operation.
Generator Exercise
If use of the generator is infrequent, exercise
the generator once a month by operating it at
approximately half the maximum rated output
for two hours. This exercise will help promote
better starting, more reliable operation and
longer engine life. This procedure drives off
moisture, lubricates the internal engine parts,
replaces the old stale fuel with a fresh supply,
and also promotes removing oxides from the
electrical switches and contacts.
NOTE
Avoid short run periods of the generator.
Run the generator set under a load for a
minimum of one-half hour.
Inverter
The inverter changes DC battery power to
AC electrical power, and charges the house and
chassis batteries when hooked to shore power or
operating from the generator. Use the inverter
to supply AC power when shore power is not
available and the generator is not going to be
used as a secondary AC power source. The
inverter supplies AC power to most outlets and
appliances. Remember that using the inverter
quickly consumes house battery power. Turn
off the inverter when not in use to conserve
house battery power. The remote panel is used
to change the variable settings. The inverter is
located in a rear curbside compartment.
Providing AC Power with Inverter
To turn the inverter on:
Press the
INVERTER ON/OFF
switch at the
remote panel. If the inverter doesn’t sense AC
power from the generator or shore power, it will
provide AC power from the motorhome batteries
to most outlets and appliances. If the generator is
started or the motorhome is connected to shore
power, the inverter will automatically begin
charging.
Battery Charging with the Inverter
The inverter will automatically begin charging
when AC power is supplied from shore service
or the generator. The inverter uses a three-stage
charge cycle to charge the batteries. The charger
may be turned off, if desired.
To turn the charger on and off:
Press the switch marked
CHARGER
ON/OFF
on the remote panel.
Shore Setting:
The Shore setting in the remote panel adjusts
the amount of AC current the battery charger
can use. If hooked to less than 50 amp service,
select the proper Shore setting to help prevent
combined AC loads such as the roof air
conditioner and the charger from overloading
limited shore power service.
To Adjust Shore Power Setting:
Press the Shore button on the inverter remote.
Turn the knob on the inverter remote left or
right to scroll through shore setting options.
Press the knob to select. An arrow will appear
next to the selected setting.
NOTE
Settings 20 Amp and below limits
battery charge capacity and may
hamper ability to efficiently operate DC
electrical loads. Remember to reset to
higher amperage when available.
