## 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. - External magnetic fields needs to be taken into consideration, including a too high packing density. This may influence the relays’ electrical characteristics. - Mechanical shock impacts e.g. dropping the relays may cause immediate or post-installation failure. - Wave soldering: maximum 260°/5 seconds. - Reflow soldering: Recommendations given by the soldering paste manufacturer need to be considered as well as the temperature limits of other components/processes. 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. **==> picture [224 x 156] intentionally omitted <==** **----- Start of picture text -----**
