Emerson IC695ACC402-AB PACSystems RX3i Energy Pack
An RX3i energy pack that supports orderly CPE330 shutdown while keeping its AB hardware and firmware identity controlled.
Key Information
IC695ACC402-AB is the PACSystems RX3i energy pack specified for the IC695CPE330 CPU. It uses a replaceable capacitor pack to support the controller during a qualifying input-power interruption.
The supply path includes the energy-pack base, cap pack, dedicated CPU cable and grounding arrangement. Revision AB is linked to the manufacturer firmware record and must remain visible in service documentation.
Functions
Power-loss support
Delivers temporary DC output to the connected CPE330 so the controller can execute its designed shutdown behavior.
Stored-energy supervision
Uses IN, STAT and OUT indicators to communicate input, internal status and output availability during commissioning.
Replaceable capacitor unit
Separates the cap pack from the main energy-pack electronics so the approved stored-energy component can be serviced.
CPU-managed updating
Receives applicable firmware updates through the connected CPE330 rather than through an independent field programming port.

Installation
Assemble
Mount the supplied base, bond the ground strap and install the approved cap pack before connecting the dedicated CPE330 cable.
Energize
Apply the documented DC supply and allow charging to complete while observing the IN, STAT and OUT indications.
Verify
Prove normal CPU operation and the approved power-loss response without disturbing the cap pack during any firmware update.
Lifecycle
Track
Keep the IC695ACC402-AB AB label, firmware baseline, CPE330 identity, cable and cap-pack records together.
Protect
Do not insert or remove the cap pack while energy-pack firmware is being updated through the CPE330.
Requalify
After cap-pack or energy-pack work, confirm charge completion, healthy LEDs and the controlled shutdown response.

FAQ
Which controller is IC695ACC402-AB intended to support?
Manufacturer documentation associates this energy pack with the PACSystems RX3i IC695CPE330 CPU and its dedicated connection arrangement.
What components should accompany an IC695ACC402-AB enquiry?
Identify the CPE330, IC695CBL002 cable, IC695ACC412 cap pack, mounting base, ground strap, power supply and exact AB label.
Can the cap pack be removed while IC695ACC402-AB firmware is updating?
No. The cap pack must not be inserted or removed during the CPU-managed firmware update interval.
Why can IC695ACC402-AB take longer to become ready after a hot-inserted cap pack?
The replacement cap pack may require up to ten minutes to charge, so LED state and charge completion must be observed before testing backup behavior.
What proves IC695ACC402-AB is ready for service?
Correct IN, STAT and OUT indications, a completed charge cycle, stable CPE330 operation and a witnessed power-loss response form the acceptance record.
