5 Electrical connection
The unit must be connected by a qualified electrician.
Observe the national and international regulations for the installation of electrical equipment.
Disconnect power.
Voltage supply according to SELV / PELV.
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.
The M12 connection parts in the device comply with the ingress resistance requirements of the
standard EN61076-2-101. To adhere to the protection rating, only cables certified to this standard
must be used. The system architect undertakes to ensure the ingress resistance of cables they have
cut to length.
•
Recommended maximum cable length: 5 m (AS-i operation)
•
Recommended maximum cable length: 20 m (IO-Link operation)
Fasten the cable with a tightening torque of 0.6...0.8 Nm, observe the cable manufacturer's
specifications.
u
Carry out the fitting according to the indications of the cable manufacturer, a max. tightening torque
of 0.8 Nm is permissible.
u
During installation, place the M12 connector vertically so that the coupling nut will not damage the
thread.
u
Provide cables with a strain relief depending on the mounting conditions to avoid excessive strain
on the installation points and the M12 connections.
u
Ensure correct fit and proper assembly of the M12 connection parts. If these instructions are not
complied with, the specified protection rating cannot be guaranteed.
u
To connect the device, use M12 connectors with protection rating IP 65 / IP 66 / IP 67 / IP 69K or
higher, depending on the requirements of the application.
u
Use M12 connectors with gold-plated contacts.
u
Cover the unused sockets with M12 protective caps, tightening torque 0.6...0.8 Nm. Use stainless
steel protective caps suitable for IP69K.
In case of cables that are longer than 20 m (IO-Link operation), take the voltage drop and the
necessary minimum supply voltage of 20 V into consideration.
5.1 UL applications
To connect devices, only use UL-certified cables belonging to category CYJV or PVVA with a
minimum temperature of 80 °C (75 °C in case of a maximum ambient temperature of 40 °C).
