Power supply
The control panel is supplied with a nominal input voltage of 24 V. The electrically isolated five-pin voltage socket (X101) is used for connection to the power supply and the protective earth of the control panel.
If the control panel is connected to an industrial PC via the CU8803 transmitter box, no additional power supply to the control panel is required via the voltage socket.

The plug for the power supply is specified for 16 A and can accommodate wire cross-sections of up to 1.5 mm2. 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 control panel, so that the control panel remains switched on during voltage fluctuations. The plug is included in the delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option:
