4.3.2 Grounding the Control Panel
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.
Protective earth
The low-resistance protective earthing of the Industrial PC prevents dangerous touch voltages. The
protective earthing of the device is established via the protective conductor in the voltage connector.
EMC
NOTE
Hardware damage due to electromagnetic interference
Using the Industrial PC without functional earthing can lead to hardware damage due to electromagnetic in-
terference.
• Only use the device with functional earthing.
Electromagnetic compatibility (EMC) refers to the Industrial PC's ability not to interfere with other devices
and equipment through electromagnetic interference, and not to be disturbed by electrical or electromagnetic
effects.
For this purpose, the Industrial PC must comply with certain protection requirements. The Industrial PC has
EMC interference immunity according to EN 61000-6-2. The EMC interference emission of the device meets
the requirements of EN 61000-6-4.
The EMC of the device is improved by functional earthing. The functional earthing is established via the
grounding bolt on the device housing. Connect it to the central grounding point of the panel of the control
cabinet. Use cables with a minimum cross-section of 4 mm
