8.1 Installation
8.1.1 General regulations
● Separate laying of power and signal lines. During installation, the national safety and installation guidelines for data
and power cables must be observed.
● Separation or differentiation of the measuring system from possible interfering transmitters.
● Observe the manufacturer's instructions when installing inverters, shielding the power cables between the frequency
inverter and the motor.
● To ensure safe and trouble-free operation, the following standards and guidelines must be observed:
- IO-Link Planning Guideline, PNO Order No.: 10.911
- IEC 60947-5-2, Low-voltage switchgear and controlgear
- EMC directive
●
It is recommended to prepare a visual inspection with protocol after completion of the assembly work.
8.1.2 IO-Link
The connection from the measuring system to the IO-Link master is made as a point-to-point connection and is
implemented via a three-core unshielded control cable.
The cable length between the IO-Link master and the IO-Link device (per device) is limited to a maximum of 20 m. A
minimum cross section of 0.35 mm² is recommended.
The CCM-S is connected via a 4-pole M8 connector.
Of the three wires of the control cable, two wires are required for the supply voltage and one wire for the IO -Link
communication connection. The 0 V supply cable is also the reference potential of the IO-Link communication
connection.
According to the IO-Link specification, the CCM-S with this connection variant is compatible with "port class A". The
maximum current consumption of these devices is specifi
ed on ≤ 200 mA.
The CCM-S supports a transmission rate of 230.4 kbit/s, which corresponds to the SDCI communication mode
"COM3".
