How to Replace UPS Internal Batteries
C A U T I O N
The UPS internal batteries are heavy (see page 112). Each battery tray holds two rows of five
batteries. Use caution when handling the heavy battery trays.
To replace the battery trays in the UPS cabinet:
1. Verify that the battery circuit breaker is in the OFF (O) position (see
Figure 30 on page 49).
2. Remove the UPS front cover and set it aside (see Figure 50):
Grasp the fingergrips on both sides of the cover and pull the cover
forward firmly. Unplug the LCD cable connecting the back of the
control panel to the electronics module.
