Electromagnetic Compatibility
WARNING!
•
Risk of injury due to interference with signals and devices
Disturbed signals can cause unforeseen device reactions. Carry out the wiring in accordance with the EMC measures.
Failure to follow these instructions can result in death, serious injury, or material damage
Measures for EMC
Effect
Device assembly
Use cable clamps for the shield support,
connect metal parts over a large area.
Good conductivity due to surface contact.
Switching devices such as contactors, relays
or solenoid valves with interference
suppression units or spark suppressors (e.g.
diodes, varistors, RC elements)
Reduce mutual interference couplings.
Wiring
Keep cables as short as possible.
Avoid capacitive and inductive interference.
