Energy Packs
GFK-2741D June 2015 17
3. Energy Packs
An Energy Pack is used in conjunction with a Controller to preserve user memory in the Controller during power
fluctuations or outages.
If system power is lost, the Energy Pack maintains power long enough for a Controller to write its user memory
contents to non-volatile memory. When system power is restored, the user memory is restored if the Controller is
configured to power up from RAM.
