Installation & Configuration Guide
The IC693PWR322F is a “plug-in” module, but since it handles the primary power distribution for the entire backplane, you can’t afford a sloppy install. A short circuit on the 24V bus can fry every I/O card in the rack.
Phase 1: Pre-Installation (Est: 10 mins)
⚠️ Safety Warning:
- Completely disconnect the 24V DC source before attempting removal.
- Verify with a Fluke 115 (or similar multimeter) that no residual voltage is present on the terminal block.
- Check the wiring labels. Over time, heat makes wires brittle; handle them gently.
Phase 2: Removal & Mechanical Fit (Est: 5 mins)
- Remove Terminal Cover: Use a small flathead screwdriver to pop the door.
- Unscrew Terminal Block: You don’t need to remove individual wires; most 90-30 PSUs have a removable terminal strip. Unscrew the two long retaining screws and pull the block forward.
- Eject Module: Press the release tabs at the top and bottom of the module simultaneously and pull straight out.
Phase 3: New Module Setup (Est: 10 mins)
- Visual Check: Ensure the backplane pins on the new IC693PWR322F are straight.
- Slide & Click: Slide the module into the leftmost slot of the baseplate. It must click into place to ensure a solid ground connection.
- Reconnect Power: Re-attach the terminal block.
- Testing: Apply 24V DC. The “PWR” LED should be solid green. If it flickers or stays off, immediately cut power and check for a short in the backplane.

Customer Cases & Industry Applications
Case 1: Food Processing Line – 4-Hour Emergency Fix Background: A beverage bottling plant in the Midwest used a GE Series 90-30 for their conveyor synchronization. The old power supply (Revision C) failed during a washdown, likely due to internal moisture. Task: The plant was losing $8,000 per hour. Local distributors only stocked the newer RX3i parts, which aren’t backward compatible. Action: They found our IC693PWR322F stock online at 10 AM. We dispatched the unit via a “Next Flight Out” courier. Result: The module arrived by 2 PM. The maintenance team swapped it in 15 minutes. Production resumed before the evening shift began, saving nearly $50,000 in potential waste.
Case 2: Wastewater Treatment Plant – Proactive Modernization Background: A municipal water facility had several 90-30 racks running on 20-year-old power supplies. They started seeing “CPU Reset” errors during heavy pump startups—a classic sign of a dying PSU capacitor. Task: The budget didn’t allow for a full migration to RX3i yet. They needed to stabilize the existing system for another 3-5 years. Action: The facility manager purchased 5 units of the IC693PWR322F (Revision F, which has improved thermal management). Result: Replacing the aging power supplies eliminated the “ghost” resets. The manager noted: “It’s a 500 fix to prevent a 50,000 headache.”
Frequently Asked Questions (FAQ)
Q: What does the “F” suffix at the end of the model number mean? A: In GE nomenclature, the letter represents the “Revision” level. The IC693PWR322F is a later revision of the original PWR322. It is 100% backward compatible with older versions (A, B, C, D, E). In my experience, the ‘F’ revision is more robust against voltage ripples than the early 1990s versions.
Q: Can I use this to replace a PWR321? A: Yes, but only if you have 24V DC input. The PWR321 is a standard capacity (15W) supply. The IC693PWR322F is a high-capacity (30W) version. It provides more “juice” for power-hungry modules like high-density 32-point I/O or communication cards. It’s a great upgrade.
Q: Does this module support battery backup for the CPU? A: No. In the Series 90-30, the battery is usually located in the CPU module or attached to the baseplate, not the power supply itself. The IC693PWR322F purely handles the DC-to-DC conversion for the backplane.
Q: Why choose “New Surplus” over a $100 used unit from a liquidator? A: Simple: Capacitors. Power supplies rely on electrolytic capacitors that dry out over time, especially if they’ve been sitting in a hot cabinet for 10 years. A “used” unit is a ticking time bomb. Our New Surplus units have never been energized, meaning the components are fresh and ready for a full service life.
