& 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.
Modifications in the sense of technical progress are reserved.

-In / Drop-Out Voltage and Coil Resistance will change at rate of 0.4% per °C.
Re-closure of Form B may occur if the max. coil voltage is exceeded. Coil polarity on Form B must be observed. Pin 2 is positive.
