NOTE
Pre-assembled cables with open cable end at one end:
Information about pin, signal and wire color assignments can be found in the appendix,
see "Signal assignment of cables with open cable end at one end", page 74
.
NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
All electrical connections of the device are configured as M12 round connectors.
The enclosure rating stated in the technical data is achieved only with screwed plug
connectors and protective elements on any unused M12 connections.
Shielding requirements
■
To ensure a fault-free data transmission, an effective and comprehensive shielding
solution must be implemented.
■
Apply a cable shield at each end, i.e. in the control cabinet and at the device.
■
The cable shield of the pre-assembled cables is guided over the knurled nut of the
cable heads.
■
After plugging in and fixing the cable heads, the screen is connected to the device
housing over a large area.
■
The cable shield in the control cabinet must be connected over a large surface to
the ground potential on the potential equalization conductor.
■
Take appropriate measures (e.g. earthing method) to prevent equipotential bond‐
ing currents from flowing through the cable shield.
■
During installation, pay attention to the different cable groups. The cables are
grouped into the following four groups according to their sensitivity to interference
or radiated emissions:
°
Group 1: cables very sensitive to interference, such as analog measuring
cables
°
Group 2: cables sensitive to interference, such as device cables, communica‐
tion signals, bus signals
