12-Volt Dc System; Converter - venture SPORT TREK Owner's Manual

The circuit breaker or fuse in the electrical panel which supplies power to
the circuit provides this protection.
Incoming polarity is extremely important. You should be certain that the
polarity of the external power is not reversed, in order to avoid harm to
appliances and personal electrical shock. Polarity testers may be
purchased in most electrical and hardware stores with the GFCI tester
built in.
During use of the recreational vehicle, it is suggested to test the GFCI
receptacle once per month. To test, press the "TEST" button in. The
"RESET" button should pop out. Power should now be turned off at this
receptacle and any receptacles down line. To restore power, push, then
release the "RESET" button.

12-volt DC System

Most interior lights and appliances receive 12-volt DC power through
converter output and/or the auxiliary battery. Exterior lights and brakes
also use 12-volt DC power from the tow vehicle battery, through the 7-
way connector and/or auxiliary battery through and wire attached to the
tow vehicle.

Converter

The heart of your 12-volt DC system is enclosed inside of the load center,
including 12V fuse panel, 120V breaker panel and converter.
The fuse panel may have 6-14 fuse positions, depending on output size
of your converter. There are also 2-40 amp fuses in converter to protect
against someone hooking an auxiliary battery up backwards.
All converters have solid state electronic components internally to
produce "clean" 12V DC power.
This load center will have a brown plastic front with a small door to access
fuses and breakers.
Some models have fuses and breakers in a separate distribution box
when 50 amp service is installed.
The function of a free standing converter used on the 50 amp system
takes 120-volt AC power and transforms this power into 12-volt DC power
as used in your coach. 12-volt DC supplies power for some appliances
and most interior lights. The floor plan and size of coach indicates the
output size.
When the converter receives 120 AC power, it transfers power into 12-
volt DC without any manual switches. The converter also charges the
auxiliary battery(s) when installed on the coach and is attached to 120-
