1. Safety
Please ensure that the detailed operating instructions and the chapter on "Safety" in particular have
been read and understood by all personnel involved in the installation, start-up, operation,
maintenance and repair of the actuators.
Caution! Dangerous electrical voltage can be present! Avoid personal or material damages by
observing applicable regulations and safety standards!
Please protect all of the power supply and control cables in front of the
terminals mechanically by using suitable measures against unintentional
loosening. Never install the power supply and the control cables together in
one line but instead please always use two different lines!
Danger! This sign warns of hazards posing a risk to health. Ignoring these instructions can lead to
injuries.
Attention! Observe precautions for handling. Electrostatic sensitive devices.
2. Operating conditions
• Standard actuators may be operated at ambient temperatures according to the data sheet.
• Operating modes correspond to IEC 60034-1, 8: S2 for short cycle, and S4 for control operation (actuator-specific
values see actuator-specific data sheets).
• For protection against moisture and dust, enclosure rating is IP65 (optionally IP67) according to EN 60529.
• The actuators must be installed with sufficient clearance to remove the cover (Figure 1). The mounting position is
arbitrary with the exception of "cover down" (Figure 2).
