Extended Runtime Modules
Extended Runtime Modules (ERMs) are supported by the Compaq UPS R3000 XR. The UPS
rear panel provides a power receptacle where the module is attached. The UPS R3000 XR ERM
contains two battery packs in a 2U chassis and extends the available UPS runtime up to 30
minutes.
NOTE: These figures were derived using the Compaq-recommended 80 percent load.

Replacing ERM Battery Packs
NOTE: The battery packs can be replaced (hot-swapped) without powering down the UPS.

To remove battery packs from an ERM:
1. Switch the circuit breaker on the rear of the ERM to the Off position.
