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 near the
battery disconnect.
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 near the battery disconnect.
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.
FOR MORE INFORMATION
Refer to the product manufacturer's owner's manual and links in Newgle to learn more about your coach's inverter,
converter, or inverter/converter combination unit.
LIGHTING
A Newmar coach's electrical and lighting system is designed for maximum reliability, functionality,
and style. Your coach may feature traditional on/off switches or multi-switch touch panel light and
accessory switch panels. Located throughout the unit, these switching devices are used to turn
lights on and off, as well as to operate power shades and window treatments. Many coach models
boast LED accent lights and new cloth-shaded LED wall sconces custom-designed for Newmar.
OPERATING INSTRUCTIONS
Flip the switch or touch the switch panel to operate the light or accessory you desire. Some lights may also have
dimming features, allowing you to adjust the interior lighting for mood or comfort.
REPLACING THE LIGHT BULBS
Replace any exterior light bulbs or fixtures as needed to maintain DOT safety requirements. When servicing interior or
exterior lights, make sure you replace any light bulb with the same bulb number (normally stamped on the base of the
