Grounding the Chassis
- Attach a ring lug to a 2.0 mm2 (14 AWG) or larger wire.
- Remove the grounding screw from the grounding terminal on the right side of the chassis.
- Attach the ring lug to the grounding terminal.
- Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
- Attach the other end of the wire to the grounding electrode system of your facility using a method appropriate for the application.
Note If you use shielded cabling to connect to a C Series I/O module with a plastic connector, attach the cable shield to the chassis grounding terminal using 1.3 mm2 (16 AWG) or larger wire. Attach a ring lug to the wire and attach the wire to the chassis grounding terminal. Solder the other end of the wire to the cable shield. Use shorter wire for better EMC performance.
