7.4. Opening and Closing the Housing
Opening:
→
Loosen seal, if housing has been secured.
→
Open the plastic hood by turning counterclockwise (all the way,
approx. 1.5 cm).
Closing:
→
Put the plastic hood on the lower part such that the inner lugs are
positioned over the fastening grooves and the external sealing lugs
are positioned almost over each other. Press the hood completely
over the seal of the lower part.
→
Turn the hood by approx. 1.5 cm clockwise (meaning until the
sealing lugs are positioned over each other).
A seal or a hood safeguard is required in an explosion-risk
area!
