4.3.2 Grounding the Panel 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.
On the back of the Panel PC, next to the interfaces, there is the grounding bolt, via which the functional earth
of the PC is ensured (see Fig. 15). Use cables with a minimum cross-section of 4 mm
2
for the ground
connection.

Protective earth
Establish low-resistance protective earthing of the Panel PC via the voltage connection to avoid dangerous
touch voltages. There is a pin in the voltage socket for the protective earth (PE).
EMC
NOTE
Hardware damage due to electromagnetic interference
The use of the Panel PC without a functional earth can lead to material damage due to electromagnetic in-
terference.
• Only use the device with functional earth.
Electromagnetic compatibility (EMC) of the Panel PC includes on the one hand not affecting other devices
and equipment by electromagnetic interference and on the other hand not being disturbed by electrical or
electromagnetic effects itself.
To do this, the Panel PC must comply with certain protection requirements. The Panel 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 functional earth is necessary for the EMC of the device.
