NOTE!
The SmartTurn control unit is not a safety
component as defined in the Machinery Directive. If
when operating the turntable, risks can occur that
demand the use of safety functions in accordance
with DIN EN ISO 13849-1, then safety switching
devices must be used that safely interrupt the
activation of the power contactors, and thus stop
the turntable.
