Description
Product Introduction
The difference between a controlled shutdown and catastrophic memory loss often comes down to a single module. The GE IC695ACC402 is an energy pack designed exclusively for the PACSystem RX3i CPE330 CPU, providing temporary power during outages to transfer RAM contents to non-volatile Flash memory .This unit offers approximately 5 years of capacitor pack life expectancy and operates across a -25 to 60°C temperature range . It connects via the dedicated IC695CBL002 cable and sources power from the RX3i backplane for charging .

Quality Control Process (SOP Transparency)
We test energy packs with the same rigor as safety-critical components—because memory integrity is exactly that. Here is the verification sequence.
- Incoming Verification: Validate part number against Emerson’s active product list. Check manufacturing date code—the 5-year clock starts at manufacture. Inspect Samtec connector pins for gold plating integrity and alignment.
- Live Functional Test: Connect to test CPE330 CPU using IC695CBL002 cable. Simulate power loss with controlled DC supply cutoff. Verify CPU successfully writes test program to Flash before energy depletion. Monitor all three status LEDs throughout the discharge cycle.
- Electrical Parameter Test: Measure insulation resistance at 500 V between power conductors and casing (>100 MΩ). Verify backup trip voltage triggers at 16.7 VDC ± 4%. Check charging circuit activates within 2 seconds of power restoration.
- Firmware Verification: No firmware, but record capacitor bank manufacturing batch code. Photograph status LED patterns during charge, discharge, and fault conditions.
- Final QC & Packaging: Inspector signs off after confirming full discharge/recharge cycle. Seal in anti-static bag with desiccant. Bubble wrap and carton with QC label showing test date and remaining capacity estimate.

Replacement Pitfall Guide (Field Engineer’s Warnings)
The GE IC695ACC402 has specific failure modes that only appear during actual power loss. Keep these five points in mind and you’ll eliminate roughly 90% of rework.
- ❗ CPU Exclusivity: Only works with CPE330—not CPE305, CPE310, or later CPUs . Case: An engineer ordered this for a CPE310 system—the cable connected but the CPU never recognized the pack, leaving memory unprotected.
- ❗ Cable Specificity: Requires IC695CBL002 (1 m), not IC695CBL001 . “The pin assignments differ. Using the wrong cable prevents status monitoring and can damage both the energy pack and CPU.”
- ❗ Temperature Impact: Capacitor life degrades rapidly above 50°C . Installation near heat sources cuts the 5-year life expectancy significantly—measure ambient temperature at the mounting location.
- ❗ Backplane Power Dependency: The unit charges from backplane power . If the backplane supply is unstable or undersized, the energy pack won’t reach full charge, reducing backup duration.
- ❗ Shelf Life Awareness: The 5-year clock starts at manufacture, not installation . Check the date code; a unit stored for 2 years already has 40% less usable life remaining.
