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.
