The ground of the MMC power source must be connected directly to a Single Point Ground (SPG) tie block. The tie block should be made of brass or copper, bolted or brazed to the control cabinet. If the tie block is bolted rather than brazed, scrape away paint or grease at the point of contact. Put star washers between the tie block and the cabinet to ensure good electrical contact. Metal enclosures of power supplies, drives, etc., should also have good electrical contact with the SPG.

Devices to be connected directly to the Single Point Ground include

1. Plant safety ground. 

2. Chassis ground from MMC power connector. 

3. The metal panel or cabinet on which the MMC is mounted. 

4. "Common" or "0 V" lines from power supplies that provide external power to the I/O modules and the devices to which they are connected. 

5. Chassis grounds from the devices themselves, such as device drivers, machinery, and operator interface devices.
