Wiring the Earth Ground
In an industrial environment, there might
h a v e a l o t o f d e v i c e s t h a t g e n e r a t e
electromagnetic noise, such as AC motors,
electric welding machine, power generator.
These devices will generate electric noise or
surges that might disturb communications. To
prevent those noises, the switch should be
well earthed.
In the figure- shows how to make connection.
See, Figure -4.
