Compatibility Notes

• Model Specificity: Designed exclusively for XRC robot and LX CNC platforms; not interchangeable with CU01, CU03, CU04, or other CU-series boards.

• Revision Matching: Verify part number, hardware revision, and compatibility with the main CPU board before replacement.

• For Maintenance Only: Not recommended for new system builds; intended solely for servicing existing legacy equipment.

Installation & Maintenance

• Install in a clean, dry, ventilated cabinet away from corrosive gases, heavy dust, and liquids.

• Firmly insert into the designated rack slot; ensure all connectors and terminals are fully seated and locked.

• Confirm 24 V DC input is within rated range before powering on.

• Periodically inspect the board, connectors, and wiring for dust, oxidation, or loose connections.

• Do not modify circuits or connect loads beyond rated specifications; use only original or fully compatible spare parts.
