Product overview
CP39xx 16 Version: 3.1
3.3.1 Power supply
The Control Panel is supplied with a nominal input voltage of 24 V. The connection to the power supply and
the external wiring of the Control Panel is established via the 4-pin M12 socket (X101) with IP65 protection.
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.

Pin Signal Description
1 + 24 V Power supply
2 GND 0 V
3 GND 0 V
4 + 24 V Power supply
The plug for the power supply is specified for 16 A. Due to the dual connection, maximum wire cross-
sections of 4 x 0.75 mm
2
can be accommodated. For long supply lines, use 4 x 0.75 mm
2
cables to achieve a
low voltage drop on the supply lines. 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:
• C9900-P916: Power supply connector for CP39xx, round connector IP65 with strain relief for the
