## 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. - Suppressing coil diode can have a negative influence on total number of switching cycles - Reflow soldering: See the page 4. Recommendations given by the soldering paste manufacturer need to be considered as well as the temperature limits of other components/processes. ## Life Test Data **==> picture [224 x 177] intentionally omitted <==** **----- Start of picture text -----**
