Emerson IC695ACC402 RX3i Energy Pack
An RX3i energy pack that maintains CPE330 power long enough to store user memory safely during loss of system power.
Product Profile
IC695ACC402 is the PACSystems RX3i energy pack for the IC695CPE330 controller. During power loss it supplies the controller long enough to transfer user memory from RAM to nonvolatile storage.
The assembly works with the dedicated IC695CBL002 cable and includes a replaceable capacitor pack. Revision, cable and grounding details are part of a correct replacement scope.

System Role
- Supports an orderly CPE330 power-down by preserving the energy needed for memory transfer.
- Allows the CPU to monitor energy-pack status through the dedicated cable.
- Separates the replaceable capacitor pack from the complete energy-pack assembly.
- Provides local status LEDs for input, pack status and output monitoring.
Compatibility
- Use IC695ACC402 with the CPE330 controller; newer controller families can require a different energy-pack model.
- Match the complete revision and supplied IC695CBL002 cable before installation.
- Ground the supplied strap in accordance with the energy-pack quick-start instructions.
- Coordinate energy-pack firmware and CPU firmware through the documented release history.
Applications
- CPE330 installations that require preserved user memory during power failure.
- Replacement of a failed or end-of-life RX3i energy-pack assembly.
- Preventive maintenance that replaces only the capacitor pack when the complete energy pack remains serviceable.
FAQ
Which controller must be confirmed before ordering IC695ACC402?
Verify that the installed controller is IC695CPE330 and record both controller and energy-pack revisions; other RX3i CPUs can use different energy packs.
When is IC695ACC412 relevant to an IC695ACC402 maintenance plan?
IC695ACC412 is the replaceable capacitor pack, so determine whether the service scope needs only the cap pack or the complete energy-pack assembly.
What should be included in an IC695ACC402 quotation scope?
Identify the energy-pack revision, CPE330 firmware, IC695CBL002 cable, base, ground strap and whether a replacement cap pack is required.
How should the IN, STAT and OUT indicators be used after installing IC695ACC402?
Use the documented LED states with CPU diagnostics to confirm charging, pack health and output rather than judging readiness from one indicator alone.
What commissioning evidence confirms IC695ACC402 is protecting memory?
Verify normal energy-pack status, review CPU diagnostics and perform the manufacturer-approved power-loss and restart test while protecting the running process.
