6.1 Notes 51957
A qualified electrician must connect the unit.
►The national and international for regulations setting up electrical equipment must be
complied with.
The unit is only suitable for operation using SELV/PELV voltages.
►Please note the information concerning IO-Link wiring!
This unit contains components that may be damaged or destroyed by electrostatic discharge
(ESD).
►Please observe the required precautions against electrostatic discharge!
The IP rating of the overall system depends on the protection ratings of the individual devices,
the applied connection elements and the corresponding protective caps.
►Provide cables with a strain relief depending on the mounting conditions to avoid
excessive strain on the installation points and the M12 connections.
►Ensure correct fit and proper assembly of the M12 connecting parts. If these instructions
are not complied with, the specified protection rating cannot be guaranteed.
For UL applications:
►To connect the IO-Link master and the IO-Link devices, only use UL-certified cables of the
CYJV or PVVA category with a minimum temperature of 80 °C (75 °C in case of maximum
ambient temperature of 40 °C).
Wiring: →Technical data (→S. 82)
By means of basic insulation according to EN61010-1, the circuits are separated from each other and
from device surfaces that could be touched (secondary circuit with 28 V DC maximum, supplied from
mains circuit up to 300 V overvoltage category II).
By means of basic insulation according to EN61010-1, the communication interfaces are separated

6.4.2 Connect IO-Link devices for Class B operation 51960
Notes on wiring:
For Class B operation, the IO-Link device must be supplied with an additional auxiliary voltage UA
using a Y connection cable.
WARNING!
Non-compliance with the electrical separation of the circuits
>Risk of fire!
►Ensure that the external supply UA is galvanically separated from the circuit of the
IO-Link Master by assuring basic insulation (according to IEC 61010-1, secondary circuit
with 28 V DC maximum, supplied from mains circuit up to 300 V of overvoltage category
II).
►Ensure that the IO-Link devices and the connection technology support the galvanic
separation.
In case of operation as port class B, the additional digital input of the IO-Link port (pin 2) is not
available!
►Connect the connectors of the IO-Link devices via a Y
connection cable with the M12 sockets of the IO-Link ports
X01...X04.
►Connect the Y cable to 24 V DC (20...28 V SELV/PELV)
Tightening torque: 0.6...0.8 Nm
►To connect the devices, use M12 connectors with protection
rating IP 65 / IP 66 / IP 67 or higher (→Accessories (→S. 80))!
