Description

IC695ACC402  ACC402 Energy Pack

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.

The ACC402 Energy Pack may be mounted on a standard EN50022 DIN rail or directly on an equipment panel. It is designed to be mounted adjacent to the CPE330 Controller and connected to the Controller using the 1m cable provided (IC695CBL002).
Heat dissipation: A minimum clearance of 25mm (1 inch) needs to be provided on all four sides of the unit (right, left, top and bottom).

Connecting to the Energy Pack
The two connectors on the ACC402 Energy Pack mate with the corresponding two pre-wired pig-tailed connectors of the IC695CBL002 cable assembly. Insert each keyed connector as shown above and secure using the captive screws provided.
Connecting the Energy Pack to the Controller
With power to the CPE330 Controller turned off, connect the 7-pin keyed connector of the IC695CBL002 cable assembly to the mating connector on the underside of the IC695CPE330 and secure using the captive screws provided.
