6.1 Notes 34181
The unit must be connected by a qualified electrician.
►The national and international regulations for the installation of electrical equipment must
be adhered to.
The unit is only suitable for operation using SELV/PELV voltages.
►Observe the information concerning IO-Link circuits!
The IP rating of the overall system depends on the protection ratings of the individual devices
and the applied connection elements.
For UL applications:
►To connect the IO-Link master, only use cables with AWG 26 to 12 and a minimum
temperature range of 75 °C.
Wiring: →Technical data (→S. 58)
The circuits are separated from each other and from device surfaces that could be touched by means
of basic insulation according to EN61010-1 (secondary circuit with 30 V DC maximum, supplied from
mains circuit up to 300 V of overvoltage category II).
The communication interfaces are separated from each other and from device surfaces that could be
touched by means of basic insulation according to EN61010-1 (secondary circuit with 30 V DC
maximum, supplied from mains circuit up to 300 V of overvoltage category II). They are designed for
network environment 0 according to IEC TR62102.
