Emerson IC695ACC400-CA RX3i Energy Pack
A revision-controlled RX3i energy pack that supports an orderly CPU user-memory save during loss of system power.
Key Information
IC695ACC400-CA is a CA-marked revision of the PACSystems RX3i IC695ACC400 CPU Energy Pack. The energy pack powers a supported CPU long enough to write user-memory contents to non-volatile storage when system power is lost.
The base IC695ACC400 design is used with supported CPE302, CPE305 and CPE310 controllers and the approved IC695CBL001 interconnect cable. The CA suffix remains part of the requested identity and must be checked against the installed label rather than dropped from the order.
Functions
- Provides temporary shutdown energy for the CPU memory-save sequence.
- Supports battery-less retention of RX3i user memory on the documented CPE platform.
- Reports charging, charged, low-capacitance and fault states to the controller.
- Works independently of the real-time-clock battery, which continues to maintain the time-of-day function.
- Allows in-service replacement under the documented controller procedure while protecting the project with a verified backup.

Installation
- Confirm the exact IC695ACC400-CA label, CPU catalog suffix and IC695CBL001 cable before shutdown.
- Create a recoverable controller project backup and record the current %S0014 state.
- Mount the pack without cable strain and protect the connector from damage or reversed engagement.
- Allow the pack to charge fully before a controlled power-loss memory-retention test.
- Verify the restored project, CPU mode, diagnostics and time-of-day maintenance after the test.
Lifecycle
- Record low-capacitance and fault events before they become an unplanned retention failure.
- Keep the CA suffix in inventory, purchase and maintenance records when the site requires revision equivalence.
- Maintain the RTC battery separately because it performs a different retention function.
- Store spare units in clean, dry conditions and inspect the cable latch and enclosure before installation.
FAQ
What should be supplied to confirm an IC695ACC400-CA replacement?
Send the IC695ACC400-CA label, controller model and suffix, firmware, cable number, mounting position and any energy-pack diagnostic message.
Can IC695ACC400-CA be ordered without the IC695CBL001 cable?
It can be quoted as pack-only, but the existing cable must be positively identified and inspected; otherwise the supply scope should include the correct cable.
Why can the CPU status indication blink after fitting IC695ACC400-CA?
A depleted pack needs time to charge to its operating threshold. Allow charging, then check %S0014 and the controller diagnostics before declaring a fault.
How should IC695ACC400-CA be acceptance-tested?
With a verified backup, confirm charging and healthy status, perform a controlled power interruption and verify that user memory and the intended operating state are restored.
Does replacing IC695ACC400-CA eliminate RTC battery maintenance?
No. The energy pack protects user memory during shutdown; the separate RTC battery maintains the time-of-day clock.
