Under normal conditions, the original battery in your UPS will last several years.
Contact Tripp Lite for information about replacement batteries.
Battery replacement should be performed only by qualified service personnel.
The batteries are hot-swappable: it is not necessary to turn off or disconnect the
UPS and its connected load to replace the UPS’s batteries. However, when it is
convenient to do so, service personnel may simplify the replacement procedure
by pressing the OFF switch to turn power off at the UPS outlets and disconnect-
ing the UPS’s power cord from the wall outlet.
When replacing the batteries, qualified service personnel should refer to “Battery
Warnings” in the Safety section and follow this procedure:
1)
Place the UPS horizontal with the Control Panel on the right side.
2)
Remove both snap-on cover panels (A).
3)
Unscrew and remove rack handle plates (B) on either side of the UPS.
4)
Disconnect the microprocessor circuit board plug (C) located on the right
side of the UPS.
5)
Disconnect battery connectors (D). Note: while batteries are disconnected,
the UPS will not provide battery backup.
6)
Unscrew and remove the battery retaining bracket (E).
7)
Grasp pull-tab and pull out sliding battery tray (F). WARNING! On the
SU2200RT2U, the batteries are arranged in an “L” shape on the tray. Since
the tray is heaviest on the front and on the left, provide adequate support
to keep the tray from tipping.
8)
Make a detailed sketch of the batteries and the polarity, color and connec-
tion of all cables. Disconnect used batteries and dispose of them properly.
Connect replacement batteries in exactly the way original batteries were
connected. Reassemble the UPS by reversing steps 1-7. Note: you may not
receive full runtime until your replacement batteries have fully charged.
Small sparks arcing between battery connectors during battery replacement
are normal.
