Connection 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

Make sure that you first ground the panel (see chapter 4.3.1 Grounding the control panel) and then plug in all data transmission cables.

Lay the cables in the mounting arm adapter as shown in chapter 4.3.2 Routing the cables in the mounting arm adapter and then plug in all data transmission cables.

When connecting the control panel to an industrial PC with UPS output, we recommend using this for the connection. In the case of CP-Link 4, we recommend connecting the CU880x transmitter boxes to the UPS output of the PC.

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 power supply plug of the panel PC, so that the panel remains switched on during voltage fluctuations.

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

1. Plug the voltage connector into the voltage socket on the panel.
2. Connect the panel to your external 24 V power supply.
3. Switch on the 24 V power supply.
You have connected your device to the power supply.
