Operation and Maintenance Instructions

• Install in a standard ABB subrack, ensuring secure seating and proper grounding

• Use shielded cables for Ethernet, serial, and I/O wiring; separate power and signal cables

• Verify 24 V DC supply before power‑on; check LED indicators for normal operation

• Configure network, I/O, and control parameters via ABB engineering tools

• Keep the module surface clean with a dry cloth; avoid moisture and corrosive substances

• Periodically inspect connectors for oxidation or damage; tighten loose connections

• Back up configuration data before replacement; use anti‑static measures during handling

• Operate within specified temperature and humidity limits; avoid strong vibration and direct sunlight
