GE Fanuc IC695ACC402 PACSystems RX3i Energy Pack

Product Overview

The GE IC695ACC402 is a PACSystems RX3i Energy Pack designed for use with the IC695CPE330 CPU. In the event of system power loss, it maintains power long enough for the CPU to write its user memory contents to non-volatile (flash) memory, ensuring data integrity and preventing program loss during unexpected shutdowns. The IC695ACC402 is NOT compatible with CPE302, CPE305, or CPE310 CPUs — those require the IC695ACC400 instead.

FAQ

Q: What is the difference between IC695ACC400 and IC695ACC402?
A: IC695ACC400 is for CPE302, CPE305, and CPE310 CPUs. IC695ACC402 is for CPE330 ONLY. They are NOT interchangeable.

Q: How long does the capacitor pack last?
A: The capacitor pack has a life expectancy of 5 years. When the STAT LED indicates "Low Capacitance," replace the Cap Pack module (IC695ACC412).

Q: Can the Energy Pack be replaced while the CPU is running?
A: Yes, the Energy Pack can be replaced while the CPU is in operation. However, if power loss occurs while the Energy Pack is disconnected or not fully charged, memory loss may occur.

Q: What cable is required?
A: The IC695ACC402 includes a cable. For replacement, order IC695CBL002 (1.0 m / 39" cable).

Installation Guide

1. Mount the Energy Pack on the left side of the RX3i CPE330 CPU module.
2. Ensure 25 mm clearance around the unit for heat dissipation.
3. Connect the Energy Pack to the CPU using the included IC695CBL002 cable.
4. Verify LED indicators show "Charged" status after power-up.
5. Monitor STAT LED periodically for "Low Capacitance" warning.

Selection Tips

• Mandatory: Verify CPU model is CPE330 before ordering IC695ACC402.
• For CPE302/CPE305/CPE310, order IC695ACC400 instead.
• Order replacement Cap Pack IC695ACC412 proactively before 5-year life expires.
• Order replacement cable IC695CBL002 if original cable is damaged.
• The IC695ACC402 is also available as part of the IC695CPK330 kit (bundles CPE330 + Energy Pack).
