10.Grasp the battery pull tab and gently pull the battery module out of the UPS
and set it aside. (FIG. 3)
NOTE: Use Caution, the battery module is heavy.
11. Slide the new battery module into the UPS.
12.Re-install the battery retaining bracket.
13.Re-install the two retaining screws for the battery retaining bracket.
14.Verify proper polarity. Reconnect the battery connectors (red and black).
(FIG. 4)
NOTE: Some sparking may occur this is normal.
15.Place the battery connectors in the holder and then lock in place. (FIG. 4)
16.Re-install the battery door on the UPS.
17.The UPS is now ready for the normal operation.
18.Properly dispose of the old battery module at an appropriate recycling fac-
ility or return them to the supplier in the packing material that the new batt-
ery module came in.
NOTE: If the UPS has a Weak/Bad Battery Alarm after replacing the battery
module, the user must initiate a battery test to clear the Weak/Bad Battery
Alarm. To initiate a self test see section 4 "USER INVOKED BATTERY TEST".
