Grounding of the industrial PC

Potential differences are minimized and electrical currents are diverted to the ground through grounding or
potential equalization of electronic devices. This is to prevent dangerous touch voltages and electromagnetic
interference.
The protection provided by the devices may be impaired by non-intended use.
