SICK GLS621 - Data Cables

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 58.
NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
The protection class stated in the technical data is achieved only with screwed plug
connectors or protective caps.
Configure the circuits connected to the device as ES1 circuits or as SELV circuits (SELV
= Safety Extra Low Voltage). The voltage source must meet the requirements of ES1
and PS2 (EN 62368-1) or SELV and LPS (EN 60950-1).
Protect the device with an external slow-blow fuse at the beginning of the supply cable.
Connect the connecting cables in a de-energized state. Do not switch on the supply volt‐
age until installation is complete and all connection work on the device and controller
has been finished.
Perform all connection work only at ambient temperatures above 0 °C.
Connect the device only to the permissible supply voltage, see "Connecting the supply
voltage", page 36.
Wire cross-sections in the supply cable from the customer’s power system must be
implemented 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.
6.2.1 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, always use EMC-compliant cables and layouts. This applies,
for example, to cables for switched-mode power supplies, motors, clocked drives,
and contactors.
■
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)
•
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
For further information, see "Wiring data interfaces", page 37.
