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 55
.
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 protection class stated in the technical data is achieved only with screwed plug con‐
nectors or cover caps.
Design the circuits connected to the device as ES1 and PS2 circuits or as SELV circuits
(SELV = Safety Extra Low Voltage). The voltage source has to meet the requirements of
ES1 and PS2 or lower (EN62368-1) or SELV (EN60950-1).
Protect the device with a separate fuse at the start of the supply circuit.
Connect the connecting cables in a de-energized state. Switch on the supply voltage
only after complete installation/connection of all connecting cables to the device and
control system.
Perform all connection work only at ambient temperatures above 0 °C.
Connect the device only to the permissible supply voltage,
Wire cross-sections in the supply cable from the customer’s power system should be
designed in accordance with the applicable standards.
In the case of open end cables, make sure that bare wire ends do not touch. Wires
must be appropriately insulated from each other.
Wire cross-sections of the data and switching signal cables have to also be designed in
accordance with the applicable national standards.

Data cables
NOTE
Layout of data cables
■
Use screened data cables with twisted-pair wires.
■
Implement the screening design correctly and completely.
■
To avoid interference, e.g. from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
■
Do not lay cables over long distances in parallel with power supply cables and
motor cables in cable channels.
Serial data transmission (RS-232, RS422/485)
•
The possible length of cable between the device and host computer depends on
the following factors:
°
The physical version of the host interface selected
°
The data transmission rate set in the device
