Connecting cables and power supply

Notice

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.
  • Please read the documentation for the external devices prior to connecting them.

The connections are located at the rear of the panel PC.

Connecting cables

Make sure that you first ground the PC (see chapter 4.3.2 Grounding the panel PC) and then plug in all data transmission cables.

Connecting the power supply

Cables with a maximum cable cross-section of 1.5 mm2 can be used for connecting the power supply. For long supply lines, use 1.5 mm2 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 VDC power supply unit:

  1. First mount the power supply cable with the 5-pin connection strip without its strain relief housing.
  2. Plug the voltage connector into the voltage socket on the panel PC.
  3. Screw the voltage connector to the voltage socket.
  4. Connect the PC to your external 24 V power supply.
  5. Switch on the 24 V power supply.
  6. Measure the voltage on the power supply plug of the PC.
  7. Mount the strain relief housing on the 5-pin connection strip.
