Product Overview
The GE IC695ACC412 is a replacement capacitor pack module designed specifically for the GE Fanuc PACSystems RX3i platform, serving as a critical component to extend the operational lifespan of energy packs such as the IC695ACC402 and IC695ACC403 1022. Engineered to preserve user memory and ensure seamless system recovery during power interruptions, this module is a direct replacement for worn-out capacitor packs in energy storage units, maintaining backup power functionality for the CPE 330 control processing unit (CPU). Its advanced capacitor technology and rugged construction make it suitable for industrial environments where continuous uptime is essential, including oil & gas, power generation, and water treatment facilities.
Key features include 5-year capacitor lifespan under typical conditions (0–50°C), hot-swap capability for maintenance without system downtime, and self-diagnostic LED indicators (IN, STAT, OUT) for real-time monitoring of input power, charging status, and output voltage. Compliance with international safety standards (UL 508, CE Mark) and a broad temperature range (-25°C to 60°C) enhance its reliability in harsh industrial settings 15.

Key Features and Advantages
Extended Operational Lifespan: The IC695ACC412 replaces aging capacitors in energy packs, restoring their 5-year operational lifespan under standard conditions. This reduces replacement frequency by 20% compared to full energy pack replacement, making it cost-effective for remote or hard-to-access installations .
Hot-Swap Capability: Users can replace the capacitor pack while the system remains powered on, minimizing downtime during maintenance. This is critical for continuous-process industries like food and beverage production, where even brief interruptions can cause product loss .
Self-Diagnostic System: Real-time LED indicators on the energy pack provide clear status updates:
- IN: Green (input within range), red (input out of range)
- STAT: Blinking green (charging), solid green (fully charged), amber (nearing end-of-life), red (fault)
- OUT: Green (output stable), red (output fault)
This proactive monitoring enables predictive maintenance and prevents unexpected system failures .
Environmental Resilience: Withstand extreme temperatures (-25°C to 60°C) and harsh conditions in mining, arctic oil fields, and outdoor manufacturing facilities. The capacitor pack’s rugged design resists dust, moisture, and vibrations .
Applications
The GE IC695ACC412 is ideally suited for industrial scenarios requiring reliable backup power solutions:
- Oil & Gas: Safeguarding DCS systems in offshore platforms and refineries during transient power fluctuations, ensuring compliance with safety protocols.
- Power Generation: Preserving turbine control parameters and diagnostic data in power plants, preventing costly downtime during grid instability.
- Water Treatment: Ensuring uninterrupted operation of pump control logic and SCADA systems during electrical grid outages.
- Transportation: Enabling real-time diagnostics in rail and automotive testing facilities by protecting data acquisition systems.
Its long-life design and environmental resilience make it a preferred choice for mission-critical applications where reliability is non-negotiable.

Installation and Maintenance
Installation Preparation:
- Power down the energy pack and disconnect it from the CPU.
- Remove the old IC695ACC412 capacitor pack by unscrewing the housing.
- Install the new IC695ACC412 and secure it with captive screws.
- Reconnect the energy pack to the CPU and power up the system. The STAT LED will indicate charging progress .
Maintenance Recommendations:
- Conduct quarterly inspections to check LED status and voltage outputs. Replace the IC695ACC412 if the STAT LED blinks amber (nearing end-of-life) or red (internal fault).
- Clean dust from energy pack vents using compressed air to maintain optimal thermal performance.
- Store spare IC695ACC412 modules in a static-free environment at temperatures between -20°C and 70°C .
