Power Converter
The power converter converts 120-volt AC power to useable 12-volt DC power when the
shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should over-
heating occur. Overheating can be caused by operating the converter above its maximum
power output for an extended period of time, or by an obstruction to its ventilation air ow.
To reduce converter heat build keep unnecessary 12-volt lights and motors turned “o”.
Keep the converters cooling ns and fan clear of obstructions.
• . Car batteries (CCA
rating) are not designed for RV applications. If doing a lot of dry camping use a
deep cycle battery rated in amp hours only (NO CCA rating).
• If using multiple batteries they must be the same brand and type. Adding more
batteries will provide longer use of DC appliances when not on shore power but
may reduce charging eciency.
• The battery works in conjunction with the converter to supply DC power to the
RV. A battery is typically only necessary if you do a lot of dry camping or have
slideouts and/or a leveling system.
The and indicators indicate the inverter status:
• STATUS & DISPLAY LEDS - both GREEN - Unit is plugged into shore power.
The panel is in Bypass Mode and will display battery voltage in DC volts.
• STATUS LED AMBER, DISPLAY LED GREEN - Inverter Mode is active. In-
verter is ON and will display battery voltage in DC volts. (Not connected to shore
power)
• STATUS & DISPLAY LEDS - both AMBER - Inverter Mode is active. Inverter
is ON, pressing the SELECT button will display inverter power output. Display
shows power output in KW.
• STATUS LED FLASHES AMBER, DISPLAY LED IS OFF - If the unit is in In-
verter Mode, and you plug in shore power, the STATUS LED will begin ashing
AMBER and the unit will switch to Bypass Mode within 20 seconds of detecting
an AC input.
• If the STATUS LED is RED and DISPLAY LED is OFF, the display will show an
error code of E01 through E12. This indicates a fault in the inverter circuit that
needs attention. Inverter will shut down.
Refer to the Magnum Inverter manufacturers’ manual in your
warranty packet for further operating instructions, error codes,
changing inverter settings and safety information.
The power button is a power disconnect switch and
will not remove DC power from the inverter. Disconnect power
from the inverter before working on it.
