6.1 Remarks
18076
A qualified electrician must connect the unit.
►Observe the national and international regulations for the installation of electrical
equipment.
Device is only suitable for operation on SELV/PELV voltages.
►Observe the information concerning IO-Link circuits (→IO-Link circuits (→p. 17))!
The device contains components that can be damaged or destroyed by electrostatic discharge
(ESD).
►Observe the required safety measures against electrostatic discharge!
The IP rating depends on the individual protection ratings of the unit, the applied connection
elements and the corresponding protective covers.
►For UL applications: For connecting the device and the IO-Link devices use UL certificated
cables of category CYJV or PVVA with a minimum temperature rating of 100°C.
►Depending on the mounting conditions, cables must be provided with a strain relief to
avoid unacceptable loads on the mounting points and M12 connections.
►Make sure that the M12 connection parts are correctly seated and mounted correctly. The
specified protection rating can not be guaranteed if this is not observed.
Wiring: →Technical data (→p. 68)
The communication interfaces are seperated from the device supply according to EN61010-1
considering basis isolation as secondary circuit with maximum 30 V DC derived from the
applied voltage up to 300 V of overvoltage category II. The communication interfaces are
designed for a network environment 0 according to IEC TR62102.
