Energy Pack; Light-Emitting Diode Indicators (Leds) - Emerson PACSystems RX3i Quick Start Manual

Energy Pack

The CPE302 preserves user memory using an Energy Pack without the need
to periodically replace batteries. The IC695ACC400 Energy Pack powers the
CPU long enough for the CPU to write its user memory contents to the
CPU's non-volatile storage during a system power loss. Installation of the
Energy Pack is found below.
