Safety and Reliability
2.5.5. Protection against external electrical influences
Connect the control system to the protective earth conductor to
eliminate electromagnetic interference. Ensure practical wiring
and laying of cables.
2.5.6. Cable routing and wiring
Separate laying of power supply circuits, never together with
control current loops:
- DC voltage
60 V ... 400 V
- AC voltage
25 V ... 400 V
Joint laying of control current loops is permissible:
- data signals, shielded
- analog signals, shielded
- digital I/O lines, unshielded
- DC voltages < 60 V, unshielded
- AC voltages < 25 V, unshielded
