and recognize possible dangers due to their specialized training, their knowl-
edge and experience as well as their knowledge of the applicable standards.
Any hazards which could be caused in the attached control valve by the pro-
cess medium, the operating pressure and moving parts are to be prevented by
means of the appropriate measures.
The actuators are designed for use in electrical power systems.
For wiring and maintenance, you are required to observe the relevant safety
