7.6 Connection compartment
closing
If you can’t turn by hand the threaded
lid before the OR reaches the tube of the
connection compartment this means that
there are debris\dirt on the threads or that
the lid is misaligned. In this case there’s
a serious danger of threads damaging.
Unscrew the lid and check the alignement
and/or clean the threads.
Never force the rotation of threaded lid
before the OR reaches the connection
compartment, otherwise thread damage
could occur.
If you suspect that any kind of thread
damaging has occurred, suspend the
installation. The device could be no longer
safe for the installation on a potentially
explosive atmosphere. In this case contact
VIDEOTEC technical support.
Before closing the cover, check the O-ring
gasket is intact. If the gasket is damaged,
replace it with the one supplied (11.1.2
Replacing the gasket, page 27).
Verify that there is no dirt or debris.
Lubricate the threads with grease compliant with IEC/
EN60079-14 to facilitate screwing the cover on.
Arrange the cables so that there is no interference
when closing the threaded lid of the connection
compartment.

Use a 30mm wrench for closing the threaded lid of

no gap between the threaded cap and the junction
box tube after tightening the cap.

Fixing the safety grub screw is necessary to complete
product closure, to prevent unwanted unscrewing of
the threaded plug.
