Inspection

AUMA actuators and controls in enclosure protection IP 68 undergo a routine

testing for tightness in the factory.

The cable glands must be sealed against the housing at the thread with an

O-ring.

.

It is recommended to additionally apply a liquid sealing material (Loctite or

similar).

Commissioning
