Configuration DIP Switches: optimize Inverter operation depending
on your application. See Configuration section for setting instructions.
Operating Mode Switch: controls Inverter operation. See
Operation section for setting instructions.
“LINE”, “INVERT”, “LOAD” LEDs: intuitive “traffic light”
signals show Inverter operation. They also warn you if the
connected equipment load is too high. See Operation section for
instructions on reading the indicator lights.
"BATT VOLT" or "BATT VOLT/CHRG CURR" LEDs: on
all models, these three lights will turn on in several sequences to
indicate the approximate charge level of connected batteries. On
2012 models, these lights indicate the approximate charge rate of
the Inverter when the Operating Mode Switch is in the "CHARGE
ONLY" position. See Operation section for instructions on reading
indicator lights.
DC Power Terminals: connect to your battery terminals. See
Battery Connection section for instructions.
Ground Fault Interrupter (GFI) AC Receptacles: allow you
to connect equipment that would normally be plugged into a util-
ity outlet. Enhancing safety, they feature ground fault inter-
rupter switches that trip if there is excessive current on the
ground safety wire.
AC Input Cord: connects the Inverter to any source of utility-
or generator-supplied AC power. See AC Input/Output Connection
section for instructions.
Resettable Circuit Breakers: protect your Inverter against damage
due to overload. See Operation section for resetting instructions.
Remote Control Module Connector: allows remote monitoring
and control with an optional module included. See remote mod-
ule owner’s manual for connection instructions.
Main Ground Lug (front or rear mounted, depending on
model): properly grounds the Inverter to vehicle grounding
system or to earth ground. See Configuration section for instruc-
tions.
Multi-Speed Cooling Fan: quiet, efficient fan prolongs equipment
service life.
Battery Temperature Sensing Connector (select models only):
prolongs battery life by adjusting charge based on battery tem-
perature. Use with cable (included). See Configuration section
for details.
“AUTO GEN START” Connector (select models only): this
automatic generator start feature is not typically applicable in
utility/work truck applications. However, for generator-
equipped trucks, it provides crews with the option of quiet
power. See “Utilize Automatic Generator Starter Capability” in
the Configuration section for details.

Operation
After configuring, mounting and connecting your Inverter, you can
operate it by switching between the following operating modes as
appropriate to your situation:
AUTO/REMOTE: Switch to this mode during nor-
mal operational conditions. When service vehicles
are deployed, the Inverter/Charger will draw from
connected batteries to supply AC power to connect-
ed equipment. This mode also enables the optional
remote control module (included) to function when
connected to the unit. It is fine to leave the switch in this mode at the
end of the day (when service vehicles are parked) especially when
relying upon the remote control as your main control. Note: when
connected to shore power, AC power is not only routed to the bat-
tery charger but passes through to the GFCI outlets as well.
OFF: Switch to this mode during normal operational
conditions if you want to completely shut down the
unit's inverter, cut-off the remote control module's
functionality and shut off power to the AC outlets.
For extended periods of “dry dock” time, switch to
this mode if the Inverter/Charger is not plugged into shore power.
CHARGE ONLY: Switch to this mode when serv-
ice vehicles are parked and (optionally) connected to
shore power for extended periods of "dry dock"
time, as with seasonal-use trucks. This mode will
enable the unit's charger, but will disable the unit's
inverter. Note: when connected to shore power, AC power is not
only routed to the battery charger but passes through to the GFCI
outlets as well.
