Configuration
Set Battery Charge Conserver (Load Sense) Dial—OPTIONAL
In order to save battery power, the unit's inverter automatically shuts off in the absence of any power demand from
connected equipment or appliances (the electrical load). When the unit detects a load, it automatically turns its inverter
function on. Users may choose the minimum load the Inverter/Charger will detect by adjusting the Battery Charge Conserver
Dial (see diagram). Using a small tool, turn the dial clockwise to lower the minimum load that will be detected, causing the
inverter to turn on for smaller loads. When the dial is turned fully clockwise, the inverter will operate even when there is no
load. Turn the dial counterclockwise to increase the minimum load that will be detected, causing the inverter to stay off
until the new minimum load is reached.
Note: the factory setting for the dial is fully clockwise. However, based on the threshold load to which you'd like the inverter to respond, you should adjust
the dial counterclockwise to reduce its sensitivity until the inverter is active only when connected equipment or appliances are actually in use.
Connect Remote Control—OPTIONAL
Model features a 8-conductor telephone style receptacle on the front panel for use with an optional remote control module (Tripp Lite
model APSRM4, sold separately). The remote module allows the Inverter/Charger to be mounted in a compartment or cabinet out of sight,
while operated conveniently from a remote location. See instructions packed with the remote control module.
Connect Battery Temperature Sensing Cable—OPTIONAL
The battery temperature sensing function prolongs battery life by adjusting the charge float voltage level based on battery temperature.
Connect the sensor cable (the cable, sold separately, has an RJ style connector on one end and a sensor on the other) to the RJ style jack
located on the side of the Inverter/Charger labeled "Remote Temp. Sense." With user-supplied electrical or duct tape, affix the sensor to
the side of the battery below the electrolyte level. Make sure that nothing, not even tape, comes between the sensor and the side of the
battery. To guard against false readings due to ambient temperature, place the sensor between batteries, if possible, or away from sources
of extreme heat or cold. If the sensor cable is not used, the Inverter/Charger will charge according to its default 25º C values.
