1. The AC power for the control system should come from a separate system, isolated from other equipment and usage. 2. The power design should account for the initial current surge, capable of withstanding at least 10 cycles. 3. The AC grounding for the control system should be based on an isolation transformer or UPS, or in the vicinity. 4. The AC power for the control system workstations should be connected using a dedicated outlet. 5. When connecting field equipment power to several I/O interface converters, isolation bars should be used. 6. The isolation transformer or UPS is powered by the control system AC power. 7.

7. When AC and DC input connections are connected to the same terminal strip, the strip must be clearly labeled with appropriate warning signs; 8. The AC grounding wire should be of a size equivalent to or larger than the conductor size; 9. Reserve an additional wire or use a terminal box to provide a test point; 10. The resistance of the grounding system must be tested, ensuring it meets the requirements of the control system manufacturer and allows for testing with electromagnetic wave testers, relay protection testers, circuit impedance testers, and multi-functional testers.
