2.5.7.3 Impact and Vibration<br />

Consider possible influences caused by motors, compressors,<br />

transfer lines, presses, ramming machines and vehicles.<br />

2.5.7.4 Electromagnetic Interference<br />

Consider electromagnetic interference from various<br />

sources near the location of installation: motors, switching<br />

devices, switching thyristors, radio-controlled devices,<br />

welding equipment, arcing, switched-mode power supplies,<br />

converters / inverters.<br />

2.5.8 Particular Sources of Interference<br />

2.5.8.1 Inductive Actuators<br />

Switching off inductances (such as from relays, contactors,<br />

solenoids or switching magnets) produces overvoltages.<br />

It is necessary to reduce these extra voltages to a<br />

minimum.<br />

Reducing elements may be diodes, Z-diodes, varistors or<br />

RC elements. To find the best adapted elements, we recommend<br />

that you contact the manufacturer or supplier of<br />

the corresponding actuators for the relevant information.<br />
