ELECTRICAL
Generator Maintenance
Before starting your generator for the first time each day, and subsequently after each eight-hour run cycle, perform the
following checks to make sure it is ready to be used.
1. Make sure the carbon monoxide detectors in your
unit are working.
2. Check for signs of fuel or exhaust leaks.
3. Make sure there is adequate clearance around the
generator for proper ventilation. Also check for
sloping ground or any other obstructions that may
have occurred. Tall grass or other items that come
in contact with the generator may interfere with
ventilation or cause a fire.
4. Check the oil and coolant levels, and inspect for
leaks.
5. Check the battery connections to make sure they
are tight and clear of corrosion.
6. Inspect the generator compartment for road debris
or damage that might affect the performance or
safety.
7. Turn off major appliances (such as air conditioners,
televisions, and other electronics that may
excessively load the generator or may be sensitive
to initial voltage surges).
The hour meter installed on the generator calculates the
number of running hours of the generator motor. This is
used for maintenance schedules. Regular oil changes
and other maintenance performed at the prescribed
intervals will greatly extend the life of your generator.
CAUTION
!
Failure to turn off the 120 volt appliances when
starting or stopping the generator may damage the
transfer switch and/or electrical appliances.
If your coach contains an Energy Management System,
8kw generator, and three roof air conditioners, the
combined load may exceed the capabilities of the
generator. Please remember to turn off one of the air
conditioners as the 8kw generator is not intended to
run all three roof air conditioners at the same time.

Inverters and Converters
Provides basic information about the role and operation of inverters, converters, and inverter/converter
combination units.
Inverters
The inverter modifies direct current to alternating current to
provide power to specified appliances and entertainment
systems. The inverter performs this action by using
a transformer to increase the voltage and modify the
higher voltage into a useable alternating current power.
For this function to occur, the inverter must be powered,
set up, and turned on. A variety of inverters are used by
Newmar; however, most have a control panel located in the
overhead cabinet with other switches and controls.
Converters
A converter transforms alternating current or shore line
power 120 volts; to low-voltage direct current to provide
power to the coach’s 12 volt house and chassis batteries.
This function occurs automatically when 120 volts are
supplied to the converter. Converters are usually located
in the cord compartment of coaches that do not have a
inverter/converter combination unit.
Inverter/Converter
Combination Units
The inverter/converter combination provides battery
charging and allows the 120 volt power from shore power
or the generator to pass through the inverter. The inverter
performs this charging action by using the transformer to
decrease the voltage and rectify the alternating current
into useable direct current voltage. This is regulated by
internal-sensing circuitry based upon the battery bank’s
state of charge and several other factors, depending on
the coach’s particular inverter brand and type.
This type of unit also performs the inverter function. For
this function to occur, the inverter must be powered, setup
and turned on. A variety of combination units are used by
Newmar; however, most have a control panel located in
the overhead cabinet with other switches and controls.
