Configuration
Set Configuration DIP Switches
Using a small tool, set the Configuration DIP Switches (located on the front panel, see diagram) to optimize UPS System operation, depend-
ing on your application. TMU612 models include one set of four DIP Switches. All other models include an additional set of four DIP switches to
configure additional operational functions. Refer to the appropriate section to review the instructions for your specific model.

Group B Dip Switches (Not on 612 Models)
Group A DIP Switches (All Models)
Using a small tool, configure your UPS System by setting the four Group A DIP Switches (located on the front panel of your unit; see dia-
gram) as follows:
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. 9 for more information.

* Most of your connected equipment will perform adequately when your UPS System's High AC Input Voltage Point (DIP Switch #2 of Group A) is set to 135V and its Low AC Voltage Input Point (DIP Switches #3 and #4 of Group A or DIP Switch #3 for 612 models) are set
to 95V. However, if the unit frequently switches to battery power due to momentary high/low line voltage swings that would have little effect on equipment operation, you may wish to adjust these settings. By increasing the High AC Voltage Point and/or decreasing the Low AC
Voltage Point, you will reduce the number of times your unit switches to battery due to voltage swings.

Check specifications on for your unit's high- and low-charging
amp options. By setting on high charging, your batteries will
charge at maximum speed. When setting on low charging, you
lengthen the life of your batteries (especially smaller ones).
