NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
The enclosure rating 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
voltage until installation is complete and all connecting cables are connected to the
device and control.
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.
6.1.1 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.
The maximum length of cable between device and host computer depends on the
interface type and the data transmission rate.
For information on data transmission rates and lengths of cable, see "Wiring the data
interface", page 44.
