Cable routing
WARNING
WARNING
!
Voltages >25 V AC are generated and transmitted in the drive system.
Set up the wiring of the drive system in a touch-proof manner.
Only operate the drive system on an SELV or PELV power supply network.
The cable routing depends on various factors, such as:
Is the cable shielded, twisted?
Were interference-reducing measures taken?
What material and what cable routing are used in the cable duct?
Over what surface is the cable routed?
Observe the following when laying the cables:
Use a full-surface, u-shaped and, if possible, metal cable duct.
Lay the cables near the corners of the cable duct.
Separate the cables by function where possible.
Maintain distances when laying the cables.
The distances may vary depending on the zone in the switching cabinet.
If possible, all cables should be twisted pairs or twisted and shielded in function groups
(e.g., motor phases together, Hall sensors and supply together).
