The power sources listed 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,
pumps, motors, and appliances.
The 7300 series power converter is a solid-state
electronic power supply and is maintenance-free. It is
so self-sufcient 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, rst check
your 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 certied RV technician locate the circuit
trouble. Replace blown fuses only with the same type
and amperage size previously used.
If the 7300 series power converter is not working, rst
conrm 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 certied RV technician.
Converter Operation
The Parallax 7300 series electronic power converter
is designed to supply the nominal 12-volt-ltered DC
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.
note
When installing a battery (s), always observe
polarity. Connecting a battery in reverse polarity
will blow the power converter main fuses located
on the 12-volt DC 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.
When the switch is turned to STORE (off) and the
trailer is plugged into a 110-volt shoreline, the 12-
volt distribution panel will still receive power from the
converter, but the batteries are disconnected from
the system. The batteries will not be drained with the
switch in the store position. The converter will not
charge the batteries with the switch in this position.
The charge in the 12-volt batteries is replenished,
when towing, from the tow vehicle alternator through
the 7-way cord. This charge will ow to the batteries
regardless of the battery disconnect switch position.
Likewise, if on or off, the solar panel is still charging the
batteries.

The converter/charging system is the interior low
voltage electrical system that enables you to use the
interior lights, fans, pumps, and 12-volt appliances,
whether operating on self-contained battery power or
120-volt city power. The 12-volt light bulbs give off the
same light as regular household bulbs, so that when
operating on self-contained battery power, everything
works normally except the 110-volt convenience
outlets and 110-volt appliances. The converter system
is designed to maintain constant output voltages
regardless of the variances that occur in city power
systems.
12-Volt Power Circuits
The current in the converter system is 12 volts direct
current (12 VDC) negative grounded. Power sources
that supply 12 VDC current to the system are as
follows:
• Main charge line from tow vehicle
• Trailer batteries
• Converter
