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 distribu-
tion fuse panel that distributes current to interior branch circuits. The circuits
provide power to operate all 12-volt DC lights, pumps, motors and appli-
ances.
The 7300 series 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 lights and appliances always work. If any 12-volt appliance
fails to operate, first check your recreational vehicles 12-volt distribution fuse
block located behind the decorative front door in the front right hand corner 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 7300 series 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 RV 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.
CONVERTER OPERATION
The MagneTec 7300 series 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 con-
verter does not require a battery to be connected to it for proper operation.
nOTiCE
: When installing a battery (s) always observe polarity. Connecting a
battery reverse polarity will blow the power converter main fuses located on the
12 volt D.C. distribution fuse block.
