2) Please refer to circuit recommendation diagramm for coil 001.
3) Requires external coil economizer, min. clamp voltage 36V (see circuit recommendation).
4) Duration min. 100ms and max. 2s to avoid over temperature.
5) Fully compliant with shock and vibration requirements.
6) Avoid repetitive switching. The average dissipated power within a period of 10 seconds
should not exceed 10W.
