Limit and torque switches
If different potentials are to be switched simultaneously, additional switches
must be used (not possible for torque switching).

Fitting the cover
After connection:
When connecting via terminals, refer to drawing, page 32.
When connecting via AUMA plug/ socket connector, refer to drawing,
page 33).
.
For AUMA plug/ socket connector, insert the socket carrier (2) into the
plug cover (1) and fasten with screws (04).
.
Clean sealing faces at the terminal cover or plug cover and the housing.
.
Check whether O-ring is in good condition.
.
Apply a thin film of non-acidic grease (e.g. Vaseline) to the sealing faces.
.
Replace terminal cover or plug cover and fasten bolts evenly crosswise.
.
Fasten cable glands with the specified torque to ensure the required
enclosure protection.
