Configuration

Note: Tripp Lite recommends that users only change settings for the DIP switches and controls described below. Additional DIP switches and
controls located in the unit's DIP switch panel or in other areas are preset to optimize the unit's operation. Setting these DIP switches or controls
may adversely affect the unit's operation.

Select Battery Type—REQUIRED
(All models)

CAUTION: The Battery Type DIP Switch setting must
match the type of batteries you connect, or your batteries
may be degraded or damaged over an extended period of
time. See “Battery Selection,” p. 6 for more information.

Switch is present to ENABLE, which
permits continuous battery charging. If you
are connecting your unit to batteries with a

Group A DIP Switches (All Models)

Using a small tool, configure your Inverter/Charger by setting the four Group A DIP Switches (located on the front panel of your unit; see diagram) as
follows:

* Most of your connected appliances and equipment will perform adequately when your Inverter/Charger’s Low AC Input Voltage Point (DIP Switch #3 and #4 of Group A) are set to 95V. However, if the unit frequently switches to
battery power due to momentary low line voltage swings that would have little effect on equipment operation, you may wish to adjust this setting. By decreasing the Low AC Voltage Point, you will reduce the number of times your
unit switches to battery due to voltage swings.
