Pay special attention to:
- Vibrations.
- Thermal expansion of the tubes.
- Excessive welding.
- Overloading of the pipelines.
Fittings:
Ensure that the connections are tight.

struction 5 on page 13.
Welding into a manifold:
Maintain the minimum clearance (A) so that the
actuator can be removed.
Electrical connection:
1. Remove the black cover from the actuator.
2. Fit the cable through the cable gland and
connect it to the terminal strip. Ensure
correct polarity (11 = +,12 = -)!
3. Tighten the cable gland and refit the cover.
- Always read the technical data
thoroughly (See page 14).
- Always release compressed air after
use.
