## Handling & Assembly Instructions ~~_~~ 

- Switching inductive and/or capacitive loads create voltage and/or current peaks, which may damage the relay. Protective circuits need to be used - see our website. 

- External magnetic fields and magnetic effects, due to adjacent relays in high density matrices that may influence the relays' electrical characteristics, must be taken into consideration. 

- Mechanical shock impacts, e.g. dropping the relays, may cause immediate or post-installation failure. 

- Wave soldering: maximum 260°C / 5 seconds. 

Please note: All technical specifications on this series datasheet refer to the standard product range. Modifications in the sense of technical progress are reserved. For general information only. For more specific information, please consult the product datasheet, available upon request. 

This series datasheet could contain technical inaccuracies or typographical errors. Changes are periodically made to the information herein. These change will be incorporated in future revisions. 

For deviating values, most current specifications and products please contact your nearest sales office.
