4.3 Connecting the Control Panel
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 is required to supply 24 V DC (-15 %/+20 %) for operating the device.
Wire the Industrial PC in the control cabinet in accordance with the EN 60204-1:2006 standard on Protective
Extra Low Voltage (PELV) so that one side of the circuit or a point on the power source of this circuit is
connected to the protective conductor system.
Set "PE" and "0 V" (24 V power supply) to the same potential (connected in the control cabinet).
Connected devices that have their own power supply must have the same potential for "PE" and "GND" as
the Industrial PC system (no potential difference).
4.3.1 Installing the supply cable
Install the cable for the voltage supply of the Control Panel using the material supplied for connector
assembly. It consists of a 5-pin connection strip and a strain relief housing with cable tie.
Installing the supply cable
First mount the plug on the cable as follows:
1. Remove the insulation from the cable ends (8-9 mm).
2. Screw the cable ends into the 5-pin connection strip. For the pin assignment of the connector, see
Chapter 3.2.1 Power supply [ } 10] .
Assembly of the strain relief housing
Now mount the strain relief housing on the previously connected plug and supply cable as shown in Fig. 14:
1. Thread the cable tie into the lower part of the strain relief housing (section A).
2. Insert the connection strip into the lower part of the strain relief housing (section B).
3. Tighten the cable tie and remove the plastic tab (section C).
4. Attach the upper part of the strain relief housing by snapping it onto the lower part (section D).
