Motor Overload Protection
NOTICE
Each motor must be protected against thermal overload.
Soft starter DS7 requires against thermal overload an combination with an
overload relay (PKZ, PKE) or a bimetallic relay (ZB).
If two or more motors are connected behind the soft starter, each engine must
be separately protected against thermal overload.
