hexagon socket screws.
Only when both connection boxes with their seals are inserted
and secured in the way specified does the housing conform to
enclosure rating IP65.

shield to the strain relief on the LSI end only. The shield is not
connected on the PLS end. Pay attention to the pin
assignment.
