Mounting a T reducing branch piece
The T reducing branch piece can be used to create a right-angled branch
from the main duct with a narrower duct. The following reductions are
possible:
•
250 mm-wide duct routing (BSKM 1025) to a right-angled duct branch
section of width 110 mm (BSKM 0711)
•
250 mm-wide duct routing (BSKM 1025) to a right-angled duct branch
section of width 70 mm (BSKM 0407)
•
110 mm-wide duct routing (BSKM 0711) to a right-angled duct branch
section of width 70 mm (BSKM 0407)
The lock plate suspended from threaded rods (BSKM-GR 0711 or BSKM-
GR 1025) is used as a support element for the duct sections. Together
with the screwed-on T reducing branch piece (BSKM-TR 0711, BSKM-TR
1025, BSKM TRK 1025), it ensures the necessary tightness.
See Fig. 58:
1
Stick the self-adhesive sealing strip to the lock plate.
Fasten the threaded rods to the ceiling and fasten the lock plate to
2
the threaded rods with washers and nuts at the desired height.
Shorten the ducts as necessary and then re-drill the duct fastening
3
holes (see Fig. 12 on page 18). If necessary, use locking brackets
for the duct lid (see "4.4 Inserting locking brackets" on page 19).
Remove the duct lid and fix the duct sections with two self-tapping
screws each (contained in the scope of delivery of the lock plate) on
the lock plate.
Comply with the minimum bending radii of the cables!
Cables can be damaged on bending. When laying the cables in the T re-
ducing branch piece, ensure that the minimum bending radius, prescribed
by the cable manufacturer, is observed.
4
Insert cables.
5
For duct BSKM 1025: insert lid support (see "4.5 Using lid support"
on page 20).
6
Attach the duct lid firmly.
7
Attach the T reducing branch piece and screw on with the supplied
nuts.
8
Using connecting screws (contained in the scope of delivery of the
T branch piece), create the equipotential bonding (see "8.1 Create
equipotential bonding" on page 72).
