Max. Reverse Polarity Protection
Fuse size: 30A
A: AC DISTRIBUTION PANEL
This panel contains the AC breakers for each of the 120 VAC branch circuits
of the RV. To turn AC breakers ON or OFF, switch breaker handle. Breaker
posistion is indicated by visual ON, OFF. To reset a tripped breaker, switch
breaker handle OFF, then ON
B: DC DISTRIBUTION PANEL
This panel contains the 12 volt DC fuses for each of the 12 VDC load circuits
of the RV. The DC distribution panel is designed for blade type fuses with a
maximum size of 20 amperes. If a fuse blows, do not replace with a fuse larger
than indicated on the label.
C: Power Converter - 120 VAC TO 12 VDC
When 120 VAC is connected to the Power Converter section either via
commercial power or generator, the converter will automatically provide the 12
volt DC power to operate the 12 volt DC power lights and 12 volt DC motors in
the RV. When 120 VAC is not connected to the Power Converter section, the RV
storage battery(ies) automatically provide the necessary 12 volt DC to operate
this equipment.
D: BATTERY CHARGING SECTION
When 120 VAC is connected to the Power Converter section, the total DC
amperage output of the converter is available for recharging the RV battery(ies),
minus current used by 12 volt load equipment.
E: INSTALLATION REQUIREMENTS (HORIZONTAL MOUNTING ONLY)
Mount the series 7300 Power Plus Control to a verticle surface with the
front of the control center open to the living area of the RV. Leave adequate
room for ventilation and wire routing.
A: CONVERTER OUTPUT: CKTS 1 - 9 VDC Positive load circuits for RV 12 volt loads.
DO NOT USE HIGHER THAN 20 AMPERE FUSE.
B: REVERSE BATTERY POLARITY PROTECTION FUSES. REPLACE WITH 30
AMPERE MAXIMUM.
C: LUG FOR POSITIVE LEAD OF 12 VOLT BATTERY. Use #8 AWG CU conductor
with 90 degree Celcius insulation rating minimum.
D: LUG FOR NEGATIVE LEAD OF 12 VOLT BATTERY. Use #8 AWG CU conductor
with 90 degree Celcius insulation rating minimum.
CAUTION:
FOR CONTINUED PROTECTION AGAINST RISK OF FIRE
OR ELECTRIC SHOCK, REPLACE ONLY WITH SAME
RATINGS AND TYPE OF FUSE.
