Replacing Batteries
NOTE
DO NOT DISCONNECT the batteries while the UPS
is in Battery mode.
The EBP can be replaced when UPS is ON, but be aware that if the
utility fails at that time, the load of the UPS may NOT be protected.
If you prefer to remove input power to change the batteries, see
“UPS Turn on and Turn off”on page 46.
Replacing Tower EBPs
CAUTION
The EBP is heavy. Lifting the cabinet requires a minimum of
two people.
1. Unplug the EBP cable from the UPS. If additional EBPs are installed,
unplug the EBP cable from the battery connector on each EBP.
2. Replace the EBP(s). See“Recycling the Used Battery or UPS”on
