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 flow.
To reduce converter heat build keep unnecessary 12-volt lights and motors turned “off”.
Keep the converters cooling fins and fan clear of obstructions.
USE ONLY A DEEP CYCLE BATTERY FOR RV USE
. 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 efficiency.
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.
Reverse polarity fuse provides protection for the converter when a battery is used.
If the battery is connected backwards to the fuse board this fuse would blow pre-
venting damage to the converter.
If your lights are dimming or flickering that usually indicates an overloaded con
-
verter. Remove some of the load by turning off DC lights or appliances.
Fan is controlled by load. It will begin running at 3 to 6 amp DC draw. It increases
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 flashing
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.
Pressing the SELECT button also cycles through in-
verter settings. Inverter settings can be changed, but
12VDC must be removed from the Ignition Start Port
on the back of the inverter. Unplug the 12VDC wire(s)
on the back of the inverter to make changes to invert-
er settings. Plug +12VDC back in after settings are
changed. (See photo)
Refer to the Inverter manufacturers’ manual in your
warranty packet for further operating instructions, er-
ror codes, changing inverter settings and safety infor-
mation.
NOTE:
The power button is
NOT
a power disconnect switch and
will not remove DC power from the inverter. Disconnect
ALL
power
from the inverter before working on it.
