4.3.3 Connecting cables and power supply
NOTE
Incorrect connection procedure
Incorrect procedure when connecting the cables and the power supply can cause hardware damage.
• Follow the documented procedure for connecting the cables and the power supply.
• Always connect all cables first and only then switch on the power supply.

Connecting cables
Make sure that you first ground the PC (see chapter 4.3.2 Grounding the Panel PC [ } 24] ) and then plug in all
data transmission lines.
Connecting the power supply
Cables with a maximum cable cross-section of 1.5 mm
2
can be used for connecting the power supply. For
long supply lines, use 1.5 mm
2
cables to achieve a low voltage drop on the supply line. There should be at
least 22 V at the voltage connector of the Panel PC, so that the PC remains switched on during voltage
fluctuations.
Proceed as follows to connect the 24 V
DC
power supply unit:
1. Check the correct voltage of the external power supply.
2. Install the power cable.
3. Plug the voltage connector into the voltage socket on the Panel PC.
4. Screw the voltage connector to the voltage socket.
5. Connect the PC to your external 24 V power supply.
6. Switch on the 24 V power supply.
7. Measure the voltage on the power supply plug of the PC.
