## 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 2607/5 seconds. > Reflow soldering: Recommendations given by the soldering paste manufacturer need to be considered as well as the temperature limits of other components/processes.
