Reliability / safety 2.5.7. Location of installation Make sure that there are no impediments due to temperatures, dirt, impact, vibration and electromagnetic interference. Temperature Consider heat sources such as general heating of rooms, sunlight, heat accumulation in assembly rooms or control cabinets. Dirt Use suitable casings to avoid possible negative influences due to humidity, corrosive gas, liquid or conducting dust. Impact and vibration Consider possible influences caused by motors, compressors, transfer lines, presses, ramming machines and vehicles. Electromagnetic interference Consider electromagnetic interference from various sources near the location of installation: motors, switching devices, switching thyristors, radio-controlled devices, welding equipment, arcing, switched-mode power supplies, converters / inverters. 2.5.8. Particular sources of interference Inductive actuators Switching off inductances (such as from relays, contactors, solenoids or switching magnets) produces overvoltages. It is necessary to reduce these extra voltages to a minimum. Reducing elements may be diodes, Z-diodes, varistors or RC elements. To provide suitably designed reducing elements, we recommend that you contact the manufacturer or supplier of the corresponding actuators for the relevant information. 2 - 8
