Replacing Batteries; Preparing The Ups - HP T2200 XR User Manual

Replacing Batteries

There are two options for replacing UPS batteries:
•
Powering down the UPS before removing the batteries
•
In certain circumstances, replacing the batteries without powering down the UPS
CAUTION: While replacing batteries without powering down the UPS, the UPS is not
protected in the event of a utility power failure.

Preparing the UPS

Batteries can be replaced without powering down the UPS if the UPS is not supplying battery
power to devices (utility is present, indicating that the UPS is supplying utility power).
To replace batteries with the UPS powered down:
1. Shut down all load devices.
2. Press the Standby button to take the UPS out of Operate mode.
3. Disconnect the UPS from utility power.
4. Wait at least 60 seconds while the UPS internal circuitry discharges.
