Overtemp
Light Action
Description
Solid red
The unit is Off. The unit has turned itself Off because the power MOSFET's
are operating too hot. This can be caused by operating an AC load which
is too large for the inverter, or lack of ventilation. When the unit cools the
inverter will start operating again.
Overload
Light Action
Description
Blinking Red
The inverter is On but it is overloaded. Reduce the AC load quickly or the
inverter will shut off due to the overload condition.
Solid red
The inverter is Off. An overload has occurred and the inverter has shut off
to protect itself. Once shut off, the inverter On/Off switch must be cycled to
reset the unit.
Charger High
Charge
Light Action
Description
Blinking Yellow
The charger is operating. The batteries were low and in need of a charge.
The charger is in the process of charging the batteries to the bulk voltage.
The charging current is limited based on the position of the Charger High/
Low switch.

ance
Light Action
Description
Solid Green
The charger is operating. The batteries are near full charge and the
charger is in the maintenance mode. In this mode, the charger is holding
the batteries at the float voltage. The charging current is limited based on
the position of the Charger High/Low switch.
Section 3: Installing the IFM1 Interface Module
This section describes the installation of the optional Vanner Model IFM 1 Interface Module.
Refer to the information provided in the IFM 1 Interface Module Owner's Manual for
information on installing the inverter and interface module in a vehicle rewired or retrofitted
for the 20-1050C UL.
If you are installing a new 20-1050 CUL unit, you will need the interface module only if you
are using the inverter or charger status panels (p/n D06638 or D06639), Remote Switch (pin
D06781), or if you need to use the inverter lockout feature.
Installing the IFM1 Interface Module
Step 1: Mount the Interface Module.
Mount the interface module in the vehicle's existing 12 V electrical system wiring harness with #8
screws. Select a physical orientation best suited for your application environment; however, it must be
close to the inverter as the interface cable is 2 ft. in length. Additionally, the unit should not be
installed with pin connections facing upward.
Step 2: Connect the inverter to the Interface Module.
Install the 2 ft. interface cable by plugging it into the remote RJ-11 connector on the 20-1050CUL, and
the J1 connector on the IFM1 Interface Module.
