The Ordinance on Industrial Safety and Health (Germany)
2.1.4
General safety instructions
The device may be fitted and started in operation only by qualified personnel who are familiar
with the fitting, start up and operation of this product.
Qualified personnel within the meaning of these installation and operating instructions are those
persons who, due to their professional training, knowledge and experience as well as their
knowledge of applicable standards can assess the work assigned to them and recognise
potential dangers.
With regard to devices designed to be explosion-proof, the personnel must be trained or
instructed, or have permission, to work on explosion-proof devices in potentially explosive
plants.
Hazards that may arise at the control valve from the flowing medium and the operating
pressure, as well as the actuating force and from moving parts must be prevented by adopting
suitable measures.
If there is a possibility of excessive movements or forces due to the magnitude of the supply air
pressure in pneumatic actuation, the supply air pressure must be limited by a suitable reducing
station.
The exhaust air opening must not be closed by the customer.
Appropriate transportation and proper storage of the device are taken as given.
