7.9.4 Connect Battery
By default, the Liebert AC8 checks the battery and sounds an alarm when the power fails, the battery
runs low or the battery needs to be checked. The battery’s main purpose is to provide enough power to
the modem to notify pagers of a power loss.
NOTE: The battery will continue to power and provide full operation of the Liebert AC8 with the
exception of powering the analog inputs (sensors). The battery will provide backup for a minimum of
10 minutes.
Using the following procedure to disconnect the battery will disable battery alarm features only. The
battery itself will continue to provide backup. If battery backup is not desired, the battery must be
unplugged from the circuit board. This can be done by removing the battery leads from the jumpers (see
Connecting the Battery Pack on page16).
The default is to connect the battery. However, there may be times that you want to disconnect the
battery so that it does not provide backup.
Table 7.12 below shows battery problems that will affect operation.
