Replace batteries with the same number and type of batteries as originally installed
in the UPS. Do not dispose of batteries in a fire. Batteries might explode when
exposed to flame.
Do not open or mutilate the batteries. Released electrolyte is harmful to the skin
and eyes and can be extremely toxic.
The 6000 VA UPS might have an extended battery module option. If there is an
extended battery module connected to the UPS, make sure that you replace the
extended battery module at the same time as you replace the internal battery
modules. For the CRU part number, see Table 11 on page 35.
If the message Service Battery is displayed and the audible alarm is on
continuously, you might have to replace the battery module. Contact your
technical-support representative to order new batteries.
Important: Do not disconnect the batteries while the UPS is in Battery mode.
Consider all warnings, cautions, and notes before you replace batteries. Disconnect
the charging source before you connect or disconnect the battery terminals.
To remove input power to change the battery modules, complete the following
steps.
Note: Qualified personnel can replace internal batteries without shutting down the
UPS and without having to remove the UPS from the rack cabinet.
1. Press and hold the on/off button until the long beep ceases (approximately 3
seconds), and then disconnect the UPS.
2. Wait 60 seconds while the internal processor shuts down before you disconnect
the battery.
