6.2 General wiring information
The device must be connected by a qualified electrician.
u
Observe the national and international regulations for the installation of electrical equipment.
The device is only suitable for operation using SELV voltages.
This device contains components that may be damaged or destroyed by electrostatic discharge
(ESD).
u
Please observe the required precautions against electrostatic discharge!
The circuits are insulated from each other and from touchable surfaces of the device with basic
insulation according to EN 61010-1.
The communication interfaces are insulated from each other and from touchable surfaces of the
device with basic insulation according to EN61010-1. They are designed for network environment 0
according to IEC TR62102).
6.2.1 Connection technology
The M12 connection parts in the device comply with the ingress resistance requirements of the
standard EN 61076-2-101. 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.
u
Carry out the fitting according to the indications of the cable manufacturer. Permissible tightening
torque: 0.6...0.8 Nm.
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.
u
Cover unused ports with M12 protective caps (art. no.: E12542).
For UL applications:
To connect the device and Ethernet devices, only use UL-certified cables belonging to category CYJV
or PVVA with a minimum temperature of 85 °C.
