SEALING CABLE ENTRIES
In keeping with best industry practices, seal all cable grommets penetrations against weather, rodent and insect
intrusions.
It is extremely important to maintain a well-sealed WIC. Failure to do so can jeopardize the enclosed electronic
equipment, as well as the proper functioning of the WIC systems. All cable transitions into the WIC must be
properly sealed as required.
Refer to the following procedure to seal cable entries with duct sealing foam:
1.
Route the cables into the WIC through bottom-entry conduits (preferred) or through side-entry conduits
in the WIC base structure (if absolutely necessary). The bottom-entry and removable side-entry plates
have pre-configured knockout stampings to facilitate conduit connections.
2.
Route the OSP cables into the WIC conditioned space by removing a Roxtec port frame from the
finished floor inside the WIC. Use a fiberglass fish tape from a side-entry port to extend to below the
Roxtec port. Reach down through the finished floor to the fish tape, and use it to route pull cord or
cables as required. Conduit knockouts are directly below each Roxtec port in the WIC base pan.
3.
Route OSP cables to equipment through the Roxtec port frame, securing to cable rack and equipment
frames as required.
4.
Seal all conduit openings with Roxtec blocks, duct sealing foam or the equivalent against weather,
animal and insect intrusion into the WIC.
5.
Replace port covers, Roxtec port frames and any other material removed during installation.
6.
Verify that cables are routed as required and that all cable entries are properly sealed.
