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.
120-VOLT AC PANEL BOARD
The AC panel board section of the series 7300 is located behind the decorative
door in the upper left-hand corner. 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 lower half of the 7300. 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.
