Thermal overload protection
The converter has a built-in protective thermal
breaker that will shut down the converter if it
becomes overheated. Overheating can be
caused by operating the converter above its
maximum limit for an extended period of time
or by an obstruction to its ventilation. The
thermal breaker will reset itself after a cool
down period and converter operation will
resume. If the converter thermal breaker trips
again shortly after an auto reset, take
immediate steps to correct the cause of
overheating. A portion of the RV 12-volt load
(lights or motors or both), should be turned
OFF to reduce the total load. Remove any
obstructions to the converter cooling fins or
fan.
Inspection and maintenance
Read the OEM operator’s manual. If the
converter is not working (or the auxiliary
battery is not charging, if so equipped), check
the two reverse polarity fuses located in the
12-volt fuse panel. There are no customer
serviceable parts in or on the converter. If the
converter box is opened, it will void the
converter warranty. If you have further
concerns contact your RV dealer.
GFCI RECEPTACLE OUTLET
Grounding is your personal protection from
electrical shock. Each RV has at least one
ground fault current interrupter (GFCI)
receptacle outlet engineered into the 120-volt
AC electrical system. It may have additional
outlets wired through, and protected by, the
GFCI. Its function is to reduce possible injury
caused by electric shock. The GFCI will not
protect against short circuits or overloads.
Test all GFCI receptacles monthly
The 120-volt AC electrical system must be on
in order to test the GFCI.
1. Plug a 120-volt AC electrical device into
the GFCI receptacle outlet.
2. Push and release the RESET button (the
120-volt AC electrical device should
operate normally).
3. Push in the TEST button.
4. The RESET button should pop out
indicating the GFCI receptacle has been
“tripped” and the 120-volt AC electrical
device should cease to operate.
If the GFCI receptacle outlet was furnished
with an indicator light, it should be lit when
the GFCI is “tripped.”
5. Push in the RESET button again and it
should hold. If the GFCI did not trip, do not
use the GFCI receptacle outlet or those
wired to it. Call your RV dealer for repair
assistance if it does not hold and pops
back out.
If an indicator light is furnished, it will be
OFF.
When the GFCI breaker is tripped, it has
interrupted ground fault current that could be
caused by faulty wire insulation, wet wiring
inside an appliance or equipment connected to
the circuit, etc. Any faulty equipment should be
repaired before your RV is used again.
Although your RV’s exterior power receptacle
(if so equipped) is not a GFCI receptacle
outlet, it is wired through and protected by the
interior GFCI.
CALCULATING ELECTRICAL LOAD
When you purchase and use 120-volt
appliances, remember your RV is limited to a
maximum load of 30 amps*. When camping
and traveling, remember that each appliance,
and 120-volt accessory places a load on your
RV’s electrical system. You may periodically
trip a circuit breaker if the combined load of
these appliances and accessories exceeds
your 30 amp rating. You can determine the
amperage rating of an appliance by dividing
the watts it uses (usually found on a label or
plate affixed to the appliance) by your RV’s
supply voltage.
For example: 1200-watts divided by
120-volts equals 10-amps.

is powered by 12-volt electricity. The 12-volt
