maximize their use.
Operating Mode Switch: controls
Inverter/Charger operation. When this
switch is set to AUTO, connected equipment
receives constant, uninterrupted utility AC
power, with simultaneous charging of
connected batteries. The CHARGE ONLY
setting prevents unwanted battery rundown
when there is no need for battery backup.
Connected batteries are recharged. When the
Operating Mode Switch is set to DC OFF,
both the inverter and the battery charger are
shut off. However, the unit will still pass
utility AC power to connected equipment if
it is plugged into an AC outlet.
Operation Indicator Lights: These
intuitive “traffic light” signals show whether
the Inverter/Charger is operating from AC
line power or from DC battery power. They
also signal an alert if the connected
equipment load is too high. See Page 5A for
details.
Battery Indicator Lights: These “traffic
light” signals show the approximate charge
level of your battery. See page 6Afor details.
AC Input Cord: Connects the Inverter/
Charger to any source of utility- or
generator-supplied AC power. See page 10A
for connection instructions. (Cord not
shown.)
AC Receptacle: Permits connection of
equipment that would normally be plugged
into a utility outlet. Note: The unit will
always pass AC power to connected
equipment if plugged into a live AC outlet,
regardless of the position of the Operating
Mode Switch.
Resettable Circuit Breaker: Protects the
Inverter/Charger against damage due to
overload. See page 6A for resetting
instructions.
Low Line Set Dial: Adjusts the AC input
voltage at which the Inverter/Charger will
switch from utility AC power to inverted
battery power. If this dial is set fully
counterclockwise, the unit will allow AC
input to drop to approximately 85V before
switching to inverter mode. Note: The unit
will continue to pass lower-voltage AC
utility power to connected equipment
until the unit switches to inverter mode.
DC Power Terminals: Connect to your
battery terminals with user-supplied cabling.
See page 9A for connection instructions.
Cooling Fan: Regulates internal
temperature and prolongs equipment service
life. Fan runs intermittently depending on
temperature and load.
Main Ground Lug: Properly grounds the
Inverter/Charger to earth ground or vehicle
grounding system. See page 9A for
connection instructions.
