Creating cable outlets
7 1
Creating an individual outlet
You can create individual cable outlets on the duct basis, but not in the
overlap areas of fittings or connectors.
V-TEC cable glands, made of brass and polyamide with a diameter of up
to 35 mm (M50), are tested and approved as outlet elements.
In addition, multiple sealing inserts, type 107 C VM, can be used in the
cable gland. It must be ensured that all the outlets of the insert are filled
with cables, in order to guarantee tightness.
Note!
T he distance between a cable outlet to a wall/ceiling penetration must be
at least 200 mm.
•
Create the openings in the duct/fitting with a step drill and de-burr
them carefully.
•
Attach the cable gland.

Creating a multiple outlet
Use the foam seal BSKM-KA 0407, BSKM-KA 0711 or BSKM-KA 1025 to
run cables with a diameter greater than 35 mm or whole cable bundles
out of the end of the duct. It can be cut and is easy to drill in order to run
cables through it. Fill remaining openings completely with the ASX abla-
tion coating (see Fig. 66).
Note!
T he distance between a multiple outlet and a wall/ceiling penetration must
be at least 500 mm.
1
Push the foam seal fully into the duct.
2
Create openings (e.g. by drilling) and run the cables through individu-
ally, or adjust the foam seal to the existing installation with a knife.
3
Attach the duct lid and seal the residual openings fully with ASX.
4
Fully seal the surface of the foam seal in this way with ASX, creating
a dry layer thickness of ≥ 1 mm.
