## **Handing & 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. 

- Suppressing coil diode can have a negative influence on total number of switching cycles, especially by switching high voltage 

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