Replacing Batteries; Preparing The Ups; Removing The Battery Pack - HP T700 series 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

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 On/Standby button to take the UPS out of Operate mode. Power to the load
receptacles ceases.
3. Disconnect the UPS from utility power.
4. Wait at least 60 seconds while the UPS internal circuitry discharges.

Removing the Battery Pack

To remove the battery pack:
1. Remove the front bezel by pulling from the bottom (1). The LED/button control pedestal
remains attached to the UPS.
2. Remove the metal battery bracket (2).
