- Power off the control system before installation; ensure the rack is securely mounted and the 24V DC power supply meets the 18-30V DC requirement.
- Use shielded cables to minimize electromagnetic interference (EMI) and follow the wiring diagram to avoid polarity errors.
- Regularly inspect for physical damage, loose connections, and dust accumulation; clean with a dry cloth.
- Check LED indicators for fault signals (e.g., red light for communication or power issues) and update firmware periodically.
- Ensure bus terminal resistance (120Ω) is correctly configured to optimize signal transmission stability.
