Hazard Areas
Please observe the following notes:
• In the event of malfunctions, shut down the valve (disconnect from the power and air
supply) and secure it against being used.
• When the valve is switching, never reach into the valve housing (391), the lantern
(9) or into the valve inlet X (on pneumatic actuators). Fingers can be crushed or cut
off.
• When releasing the grooved cap nut (252) of the non-actuated valve (spring-to-close
version) there is a risk of the bellows and the round thread of the grooved cap nut
being damaged. Before releasing the grooved cap nut (252) therefore relieve the
spring tension by pressurizing the actuator with compressed air. The valve is
opened.
• The housing sockets have very sharp edges. When transporting and assembling the
valve therefore be sure to wear suitable protective gloves.
• Before starting any service, maintenance or repair work, disconnect the valve from
the power supply and secure it against inadvertently being switched back on again.
• Only allow a qualified electrician to carry out any work on the electrical power
supply.
• Check the electrical equipment of the valve at regular intervals. Immediately remedy
loose connections and molten cables.
• If work on live parts cannot be avoided, call in a second person, who can operate
the main switch in case of an emergency.
