12V POWER CIRCUITS
The current in the converter system is 12 volts direct current (12VDC) negative
grounded.
Power sources that supply 12VDC current to the system are as follows:
A. Main charge line from tow vehicle
B. Trailer Battery
C. Converter
The power sources above are all electrically connected to the 12-volt distribution fuse
panel that distributes current to interior branch circuits. The circuits provide power to
operate all 12-volt DC lights and systems.
The power converter is a solid-state electronic power supply and is maintenance free.
It is so self-sufficient and quiet that you will probably not know it is working except
for the fact that your batteries are always charged, and your 12-volt systems always
work. If any 12-volt system fails to operate, first check your recreational vehicles 12-
volt distribution fuse panel located behind the decorative front door of the converter
and inspect all fuses. If a fuse is opened or blown replace it with the same size fuse
(never install a larger use). If the fuse opens again, have an electrician or certified RV
technician locate the circuit trouble. Replace blown fuses with Littefuse type 257
fuses only.
If the power converter is not working, first confirm the RV supply or shoreline cord is
plugged into a live circuit. Then check all the 120-volt breakers in your converter 110
volt distribution panel to make sure they are on. If the breaker is tripped, follow the
instructions to reset the breakers. If the breaker trips again, consult an electrician or
certified RV technician.
ELECTRICAL SYSTEM
CONVERTER OPERATION
The electronic power converter is designed to supply the nominal 12-volt filtered
D.C. power for all 12 volt operated devices encountered in RV service. Although the
converter is an excellent battery charger, the converter does not require a battery to be
connected to it for proper operation.
CAUTION
: When installing a battery (s) always observe polarity. Connecting a bat-
tery reverse polarity will blow the power converter main fuses located on the 12 volt
D.C. distribution fuse block.
120 VOLT AC PANEL BOARD
The AC panel board section of the converter is located behind the converter's decora-
tive door. This panel contains the 120 Vac branch circuit breakers for your RV. One of
the breakers controls the 120 volt power to the 12 volt converter section located in the
converter. This breaker may also control another branch circuit. Check the label next
to each breaker for what each branch circuit breaker controls.
The 120 volt circuits may be turned "on" my putting their breaker handle up to the on
position or "off" by flipping the handle down to the off position. To reset the tripped
breaker move handle to off then on.
CONVERTER COOLING SYSTEM
The electronic fan cooling system is the key to long life and trouble-free operation. The
fan is never on more than required to cool electronic components in the converter. You
may never hear the fan operate.
