DANGER!
Linear actuators with the cover removed may only be operated for short periods, e.g. for
test runs or essential calibration work on electric components such as potentiometers,
limit switches or position electronics. During these activities, hazardous energized, unin-
sulated, moving and rotating parts are easily accessible. If the calibration is performed
improperly or without the required caution, death, severe physical injury or property
damage may result.
This type of work may only be carried out by qualified personnel (see p. 3 "Safety in-
structions").
The operation of the actuator with the cover removed for a purpose other than the one
described above, is prohibited.
