Emerson IC695ACC400-AA RX3i Energy Pack
An AA-marked IC695ACC400 energy pack for supported RX3i CPE controllers and controlled user-memory retention.
Product Overview
IC695ACC400-AA is an AA-marked revision of the PACSystems RX3i CPU Energy Pack. Its function is to sustain a supported CPE controller long enough to copy user memory into non-volatile storage after loss of system power.
The complete AA suffix distinguishes the requested installed revision. It should be supplied with the compatible IC695CBL001 cable and verified against the exact CPE302, CPE305 or CPE310 controller platform.
Performance
- Supplies the short-duration energy required by the controlled memory-save sequence.
- Provides controller-visible charging, charged, low-capacitance and hardware-fault states.
- Supports pack replacement without changing the separate real-time-clock battery function.
- Mounts beside the rack module without consuming an RX3i backplane slot.
- Operates over the documented 0 to 60 °C temperature range.

System Integration
- Confirm the IC695ACC400-AA label, CPE catalog suffix and cable before ordering.
- Create a verified controller backup and record all current energy-pack diagnostics.
- Inspect the side-mount hardware, connector latch and cable routing before installation.
- Wait for a fully charged indication and healthy %S0014 status.
- Perform a controlled outage and verify memory restoration, controller mode and process restart behavior.
Applications
- Revision-controlled RX3i CPE302/CPE305/CPE310 maintenance.
- Battery-less preservation of controller user memory during system power loss.
- Spare strategies that retain the exact AA product release and cable scope.
- Preventive replacement after low-capacitance diagnostics.
FAQ
Can IC695ACC400-AA and IC695ACC400-CA be treated as the same stock item?
They share the IC695ACC400 base function, but the revision must remain visible and any substitution should follow the site qualification and label/approval review.
What is the main procurement risk with IC695ACC400-AA?
A pack can arrive without the IC695CBL001 cable or with an unverified suffix, so define revision, cable and mounting scope in the purchase order.
What should be done if IC695ACC400-AA reports low capacitance?
Schedule replacement under the controller procedure, preserve a current project backup and avoid relying on the pack for memory retention until health is restored.
How can IC695ACC400-AA be changed without losing user memory?
Keep the controller powered during the permitted replacement procedure, install the new pack, allow it to charge and then verify status before any power interruption.
Which test proves IC695ACC400-AA is ready for service?
A controlled power-loss and restart test with a verified backup confirms the energy pack, cable, memory-save process and intended controller recovery.
