Overview 2
1. Overview
The ACC402 Energy Pack is used exclusively with the
CPE330 RX3i CPU. It preserves user memory in the
Controller during power fluctuations or outages.
If system power is lost, the Energy Pack maintains power
long enough for the connected CPE330 to write its user
memory contents to non-volatile memory. When system
power is restored, the user memory is restored if the
CPE330 is configured to power up from RAM.
The ACC402 Energy Pack is connected to the
IC695CPE330 CPU via a dedicated cable IC695CBL002
(shown above). This arrangement allows the Energy Pack
to source power from the RX3i backplane in order to
charge its circuitry. The cable also allows the CPU to
monitor the status of the Energy Pack. Upon loss of
backplane power, the CPU automatically switches over
to the Energy Pack power source, ensuring an orderly
power-down sequence.
