With connecting an inductive load to
the SSR output, like e.g. a relay, it may
be necessary to connect a snubber circuit
in parallel to the load to protect the output
from an uncontrolled turn on.
By an uncontrolled turn on
it is possible that the load is
switched on permanently.
The snubber circuit must be
adapted to the load.
