Configuration
DIP SWITCH GROUP A
BATTERY TYPE / VOLTAGE POINT
Using a small tool, set the 4 “Battery Type / Voltage Point” Configuration DIP Switches, Group
A (located on the front panel of your APS; see Diagram 1, p. 35) to select battery type and set
the voltage range outside of which your APS will switch to battery power.
• Select Battery Type
(DIP Switch #1, Group A)
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,” page 8 for more information.

Most loads will perform adequately when your APS’s High AC Voltage
Point DIP Switch #2 is set to 135V and its Low AC Voltage Point DIP
Switches #3 and #4 are set to 95V. However, if your APS 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 raising the High AC Voltage Switch to
Battery point and/or lowering the Low AC Voltage Switch to Battery
Point, you may reduce the number of times your APS switches to
battery due to voltage swings.
