Connecting the industrial PC

CAUTION

Risk of electric shock

Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:

Never connect or disconnect the device cables during a thunderstorm.
Provide protective earthing for handling the device.

To prepare the industrial PC for operation, it must be connected. The first step is to ground the device. Then you can connect the cables and the power supply.

An external power supply unit providing 24 V DC (-15 %/+20 %) from an isolated source is required for the power supply. This source must be protected by a UL 248 rated fuse with a maximum rating of 4 A.

The cabling of the industrial PC in the control cabinet must be done in accordance with the standard EN 60204-1:2006 PELV = Protective Extra Low Voltage:

Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the energy source for this circuit must be connected to the protective conductor system.
