4.3 Connecting the Control Panel
CAUTION
Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:
• Never connect or disconnect the device cables during a thunderstorm.
• Provide protective earthing for handling the device.
To prepare the Control Panel for operation, you have to connect it. The first step is to ground the device.
Then you can connect the cables and the power supply.
An external power supply unit is required to supply 24 V DC (-15 %/+20 %) for operating the device.
Connect the Control Panel in the control cabinet according to standard EN 60204-1:2006 Protective Extra
Low Voltage (PELV):
• The PE conductor (protective earth) and the "0 V" conductor of the voltage source must be on the
same potential (connected in the control cabinet).
• Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective conductor system.
Devices connected to the Control Panel with their own power supply must have the same potential for the
PE "0 V" conductors as the Control Panel (no potential difference).
4.3.1 Mounting power supply cable
Install the cable for the power supply of the Control Panel using the material supplied for connector
assembly. It consists of a 5-pin connection strip and a strain relief housing with cable tie.
If you require a replacement for the voltage connector or the strain relief housing, you can order these from
Beckhoff Sales using the following ordering option:
• C9900-P927: power supply connector for CP69xx or CP66xx Control Panel, 5-pin connector with strain
relief for the external supply cable
Mounting power supply cable
First mount the plug on the cable as follows:
1. Remove a few centimeters of the cable sheath.
2. Remove the insulation from the wire ends (8-9 mm).
3. Crimp the ferrules onto the stripped wire ends.
4. Insert the cable ends with the ferrules into the 5-pin connection strip. For the pin assignment of the
connector, see Chapter 3.2.5 Power supply [
}
13] .
5. Screw the cable ends into the 5-pin connection strip.
ð You have mounted the plug on the cable.
Assembly of the strain relief housing
Now mount the strain relief housing on the previously connected plug and supply cable as shown in Fig. 13:
1. Thread the cable tie into the lower part of the strain relief housing (section A).
2. Insert the connection strip into the lower part of the strain relief housing (section B).
3. Tighten the cable tie and remove the plastic tab (section C).
4. Attach the upper part of the strain relief housing by snapping it onto the lower part (section D).

You have mounted the strain relief housing.
