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 the cables first and only then switch on the power supply.
  • Please read the documentation for the external devices prior to connecting them.

Connecting cables

The connections are located in the front of the industrial PC and are documented in Chapter 3.1 Structure.

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

Connecting the power supply

Cables with a maximum cable cross-section of 1.5 mm2 must be used for connecting the power supply. To achieve the lowest possible voltage drop on the supply line, we recommend connecting the maximum possible cross-section. In case of larger distances between the power source and the PC, take into account the voltage drop in relation to the cable cross-section as well as fluctuations in your supply voltage in order to ensure that the voltage at the power supply unit does not fall below 22 V.

Proceed as follows to connect the 24 VDC power supply unit:

  1. Check the correct voltage of your external power supply.
  2. Install the power cable.
  3. Plug the power cable into the voltage socket of the industrial PC.
  4. Screw the power cable to the voltage socket of the industrial PC.
  5. Connect the PC to your external 24 V power supply.
  6. Switch on the 24 V power supply.
