Configuration (continued)

B3 Select Equalize Battery Charge—OPTIONAL

This DIP Switch is momentarily engaged
	B4	B3	B2	B1	Reset
to begin the process of equalizing the
charge state of your battery’s cells by time-
limited overcharge of all cells. This can					Equalize
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.

Battery Charge	Switch Position
Reset	Up (factory setting)
Equalize	Down—momentarily

B4 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).

Battery Charger	Switch Position
Low Charge Amps	Up
High Charge Amps	Down (factory setting)

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.

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).
