Installation Guide

Safety Precautions

• De-energize the Ovation controller rack before installation
• Use proper ESD protection when handling the CPU module
• Verify firmware compatibility with existing Ovation system

Step-by-Step Procedure

1. Power down the Ovation controller rack
2. Remove the existing CPU module (if replacing)
3. Align the 5X00481G01 with the rack slot and insert firmly
4. Secure the module retaining clips
5. Connect Ethernet, USB, and serial cables as required
6. Power up the rack and verify boot sequence via status LEDs

Selection Tips

• Verify processor variant (E6400 vs D525) with your supplier before ordering
• Confirm memory and storage capacity meet your application requirements
• For redundant systems, order two identical modules with same firmware revision
• Ensure Windows Embedded Standard 7 license is included for new units
