Warning - risk of injury!
Note that the actuator position may be changed accidentally by the repelling power of the
valve when the brake is released!
Before switching on, ensure that the specified environmental conditions in the "Technical
Specifications" chapter or data sheet are complied with and that the power supply voltage
corresponds with the voltage of the actuator.
When there is a chance that safe operation is no longer possible, put the device out of operation
and secure against unintended operation.
When mounting the actuator in areas which may be accessed by unauthorized persons, take
the required protective measures.
Lock the handwheel with a cotter pin in order to a void unintentional manual actuator
