3.2.2. Select the appropriate gland depending on the cable diameter.
3.3.2. Pull on the long snapfit towards the profile till it clicks in the
UMS bracket; start on the FAS block without leaving gaps between the
plates.
3.2.3. Install the glands in the selected ports by tighten the nut on the

3.5 Mounting of the box on the wall
3.5.1. Place the template against the wall and mark the 4 mounting
positions.
4 Cable installation
4.1 Cable preparation
3.5.2. Drill the holes (dia. 6 mm, depth 60 mm) and place the plugs
into the holes.
4.1.1. Feed the cable through the cable port gland.
4.1.2. In case the cable diameter does not match with the diameter
of the gland seal, remove the plastic nut, metal ring and rubber seal
inside the gland and peel out some of the break out rubber rings up to
the right diameter.
3.5.3. Hold the base part onto the wall. Insert the screws and tighten.

1800 mm
60 mm
4.1.3 Prepare the cable according to the drawing, Strip and clean
the cable over a length of 1800 mm. and cut the strength member at
60 mm length.
For slotted core cable only
4.2. Cable termination
4.1.3.1 Install a protection tube of 150 mm. over the fibers of each slot
and slide the tube into the slot of the cable.
4.1.3.2 Protect the transition from the cable to the tubes with a few
layers of Teflon tape.
4.2.1. Pull the cable back in the correct position, the cable jacket
should protrude 30 mm into the box passing the cable strapping point.
4.1.3.3 Consider the protection tubes now as loose tubes in the
installation.

4.2.2. Insert the strength member in the strength member connector
and tighten the connector with a screwdriver. If necessary, remove the
plastic core from the strenght member till it fits in the strain relief
connector.
4.2.4 Tighten the gland.
5 Fiber routing to the individual trays
5.1 Allocation of the tubes in the tubeholders
Important. Loose tubes should be routed up to the tubeholder in such
way that access to all the tubes is possible at all times in case of rerouting without crossings of already installed tubes.
5.2 Routing of cable fibers
4.2.3 Secure the cable with a tiewrap onto the cable attachment
plate.
