Set Battery Charging Amps—OPTIONAL
Check specifications for your unit’s high- and low-charging amp
options. By setting on high charging,
your batteries will charge at maximum
speed and your RV 12V DC system
loads will be well-supplied. When set-
ting on low charging, you lengthen the
life of your batteries (especially small-
er ones).

CAUTION: When switching to the High Charge Amp setting, the user must ensure that the
amp hour capacity of their battery system exceeds the amperage of the High Charge Amp
setting or the batteries may be damaged or degraded.
Select Equalize Battery Charge—OPTIONAL
This DIP Switch is momentarily engaged
to begin the process of equalizing the
charge state of your battery’s cells by time-
limited overcharge of all cells. This can
extend the useful life of certain types of
batteries; consult with your battery’s manufacturer to determine if
your batteries could benefit from this process. The charge equaliza-
tion process is automatic; once started, it can only be stopped by
removing the input power.
Setting Procedure
• Move to “Equalize” (DOWN) position for three seconds.
• Move to “Reset” (UP) position and leave it there. This is the
factory default setting.
CAUTION: Do not leave DIP switch #B3 in the down position after beginning process. Battery
charge equalization should only be performed in strict accordance with the battery manufacturer’s
instructions and specifications.

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 sensi-
tivity until the inverter is active only when connected equipment or appliances are actually in use.
Connect Remote Control—OPTIONAL
(All models)
All models feature an 8-conductor telephone style receptacle on the front panel for use with an optional remote control module (Tripp Lite model
APSRM4, sold separately or included with select models). The remote module allows the Inverter/Charger to be mounted in a compartment or cabinet out
of sight, while operated conveniently from within the living area or control panel of your RV. See instructions packed with the remote control module.
Connect Battery Temperature Sensing Cable—OPTIONAL
(not on 750 models)
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, included with select models, has an RJ style connector on one end and a black 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 sen-
sor 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 bat-
tery. 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.
Utilize Automatic Generator Starter Capability—OPTIONAL
(not on 750 models)
All models except 750 models include an RJ type modular jack on the side
*
panel labeled “Generator Start”. Attach to vehi-
cle generator ON/OFF switching mechanism with user-supplied cable (see Pin Configuration Diagram). Once
attached, the interface will allow the Inverter/Charger to automatically switch a vehicle generator on when connected bat-
tery voltage levels are low (11.6 VDC) and switch it off when battery voltage levels are high (14.1 VDC).
* Or rear (1250 model).
