Operation
Switch Modes
After configuring, mounting and connecting your Inverter/Charger,
you are able to operate it by switching between the following operat-
ing modes as appropriate to your situation:
“AUTO/REMOTE”: Switch to this mode when you
need constant, uninterrupted AC power for connected
appliances and equipment. The Inverter/Charger will
continue to supply AC power to connected equipment
and to charge your connected batteries while utility-
or generator-supplied AC power is present. Since the
inverter is ON (but in Standby) in this mode, it will automatically
switch to your battery system to supply AC power to connected
equipment in the absence of a utility/generator source or in over/
under voltage situations. “AUTO/REMOTE” also enables an option-
al remote control module (Tripp Lite model APSRM4, sold sepa-
rately) to function when connected to the unit.
“CHARGE ONLY”: Switch to this mode when you
are not using connected appliances and equipment in
order to conserve battery power by disabling the
inverter. The Inverter/Charger will continue to sup-
ply AC power to connected equipment and charge
connected batteries while utility- or generator-sup-
plied AC power is present. However, since the inverter is OFF in this
mode, it WILL NOT supply AC power to connected equipment in
the absence of a utility/generator source or in over/under voltage
situations.
“DC OFF”: Switch to this mode to prevent the
inverter from drawing power from the batteries. Use
this switch to automatically reset the unit if it shuts
down due to overload or overheating. First remove
the excessive load or allow the unit to sufficiently
cool (applicable to your situation). Switch to "DC OFF", then back
to "AUTO/REMOTE" or "CHARGE ONLY" as desired. If unit fails
to reset, remove more load or allow unit to cool further and retry.
Use an optional remote control module (Tripp Lite model APSRM4,
sold separately) to reset unit due to overload and overtemperature.
CAUTION: The unit will always pass AC power through to con-
nected equipment if plugged into a live AC outlet, regardless of
the position of the Operating Mode Switch.
Indicator Lights
Your Inverter/Charger is equipped with a simple, intuitive, user-
friendly set of indicator lights. These easily-remembered “traffic
light” signals will allow you, shortly after first use, to tell at a glance
a wide variety of operating details.
“LINE Green LED”: If the operating mode switch is set to “AUTO/
REMOTE”, this light will ILLUMINATE
CONTINUOUSLY when your connected equipment
is receiving continuous AC power supplied from a
utility/generator source.
If the operating mode switch is set to “CHARGE
ONLY”, this light will BLINK to alert you that the
unit’s inverter is OFF and will NOT supply AC power in the absence
of a utility/generator source or in over/under voltage situations.
Indicator Lights
(Continued)
“INV” (Inverting) Yellow LED: This light will
ILLUMINATE CONTINUOUSLY whenever con-
nected equipment is receiving battery-supplied,
inverted AC power (in the absence of a utility/genera-
tor source or in over/under voltage situations). This
light will be off when AC power is supplying the
load.
“LOAD” Red LED: This red light will ILLUMINATE
CONTINUOUSLY whenever the inverter is func-
tioning and the power demanded by connected appli-
ances and equipment exceeds 100% of load capacity.
The light will BLINK to alert you when the inverter
shuts down due to a severe overload or overheating.
If this happens, turn the operating mode switch to “DC OFF”;
remove the overload and let the unit cool. You may then turn the
operating mode switch to either “AUTO/REMOTE” or “CHARGE
ONLY” after it has adequately cooled. This light will be off when
AC power is supplying the load.
"BATT VOLTAGE" LEDs: If the operating mode switch is in the
"AUTO/REMOTE" or "CHARGE ONLY" position, the LEDs indi-
cate the approximate charge level and voltage of your connected
battery bank and alert you to several fault conditions. See Chart for
charge and voltage levels.
