Enclosures
The OCX 8800 enclosures are designed to meet ingress conditions of Type
4X and IP66 (when reference air vents are routed to a dry area). Each
enclosure cover is threaded to its base and sealed with an o-ring that isolates
the threads from external contaminants.
Each cover is secured by a clip attached to the base that engages the cover
between the ribs of the cover sidewall. The clip is held in place by an Allen
head cap screw and lockwasher mounted in a recess. Cover removal and
installation requires an Allen wrench to loosen and tighten the screw.
