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 mm2 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

Notice

Hardware damage due to electromagnetic interference

The use of the Panel PC without a functional earth can lead to material damage due to electromagnetic interference.

  • 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.
