Configuration - Tripp Lite UT Series Owner's Manual

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.
Required Configuration
DIP SWITCH
1
Select Battery Type—REQUIRED
Using a small tool, set the DIP switch to
match the type of batteries you connect.
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," for more information.
Optional Configuration
DIP SWITCH
3
Select Equalize Battery Charge—OPTIONAL
(For use when using auxiliary batteries. See Battery Selection section.)
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; con-
sult with your battery's manufacturer to determine if your batteries
could benefit from this process. The charge equalization process is auto-
matic; once started, it can only be stopped by removing the input power.
DIP SWITCH 4
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. By setting on low charg-
ing (factory setting), you lengthen the life
of your batteries (especially smaller ones).
Connect Remote Control—OPTIONAL
An 8-conductor telephone style receptacle on the front panel is included for use with an optional remote control module (included). The
remote module allows the Inverter to be mounted in a compartment or cabinet out of sight, while operated conveniently from within the
cab of your vehicle. See instructions packed with the remote control module.
Connect Battery Temperature Sensing Cable—OPTIONAL—(Select models only)
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, 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 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 will charge according to its default 25º C values.
Utilize Automatic Generator Starter Capability—OPTIONAL—(Select models only)
Although not typically applicable to utility/work truck situations, select Inverter models offer an RJ type modular
jack on the side panel labeled "Generator Start." If your current fleet is already equipped with generators,
select Tripp Lite Utility/Work Truck Inverters provide your crews the option of quiet power for residential envi-
ronments or late-night job sites. When wattage loads are within the Inverter's ratings, crews can avoid the power
overkill, fuel consumption, fumes and noise of generator use. To tie the Inverter and generator together, simply connect the generator's AC
power output to the Inverter's AC input cord. The Inverter will automatically charge the battery when generator power is available, and gen-
erator power will automatically pass-through for use via the Inverter's GFCI receptacles. To automatically activate the generator when bat-
tery voltage runs low, attach to vehicle generator ON/OFF switching mechanism with user-supplied cable (see Pin Configuration Diagram).
Once attached, the interface will allow the Inverter to automatically switch a vehicle generator on when connected battery voltage levels
are low (11.6 VDC) and switch it off when battery voltage levels are high (14.1 VDC).

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.
