To avoid damage to the battery leads, be sure that the cables do not bind against the
guide rail while reinstalling the battery.
10 Connect the red battery cable.
NOTE: A small amount of arcing may occur when connecting the batteries. This is normal
and does not damage the unit or present any safety concern.
11 Replace the metal battery cover and UPS front bezel.
Testing New Batteries
NOTE: Allow batteries to charge for 6 to 24 hours before testing.
NOTE: The batteries must be fully charged and the UPS must not be in Battery mode to
perform the self‐test.
Press and hold the (Test/Alarm Reset) button for three seconds to initiate a self-test.
The 15-second test automatically distributes the load to the battery and tests the battery's
performance. While the test is in progress, the indicators cycle through and the UPS
beeps. When complete, the UPS returns to Normal mode as indicated by the

(Power On) indicator.
If there is a problem with the battery, the UPS beeps, the + - (On Battery) indicator
illuminates and the (Service) indicator flashes. Check the battery connections and be
sure the battery is fully charged. Call your service representative if the problem persists.
