Shortening the ceiling tube


Loosen the fastening screws for the socket.

Pull the socket, complete with cable, out of the ceiling
tube using pliers on the inner ring.

Before shortening the ceiling tube, remove the cable from
the ceiling tube.

Use a hacksaw to shorten the upper end of the ceiling
tube to the desired length, and then debur it.
Remove the fastening screw "C".

Insert the ceiling tube "A" into the ceiling bracket "B" and

enlarge the existing hole in the ceiling holder to 9 mm in
diameter with the drill. Drill the opposite hole separately.

Note: Pull the cable through from the lower side to the upper
pipe side (the 3-pin plug first) after sawing and drilling.

Refit the cable with the socket into the ceiling tube.

Align the threaded hole in the socket precisely with the
existing hole in the ceiling tube and install the fastening
screw.

DANGER
Assembly by qualified personnel

Assembly must only be carried out by qualified per-
sonnel. Lack of appropriate knowledge may pose a
danger to life.

Two people are needed for assembly.
DANGER
Risk of death from falling luminaire.

The ceiling mount must only be fitted to ceilings with
a concrete stability class of B25 (C20/25) or higher.

There should be no contact with the reinforcement
sections of the solid ceiling during mounting. When in
doubt, a licensed technician must approve installation
on the specific installation surface. The load-bearing
capacity of the ceiling structure must be planned,
checked and confirmed by a structural engineer
beforehand.

The holes must be drilled by a professional, in com-
pliance with the drilling tolerances permitted by the
manufacturer of the fastening anchor. If a drilling error
occurs, such as drilling into a reinforcement bar, a struc-
tural engineer must be consulted.

Install the luminaire so that the vertical stops are not
continuously stressed during operation.

With plaster or cladding coating concrete, the faste-
ning anchor must be driven completely into the concrete.

The screws must be tightened carefully using a torque
wrench according to the specifications of the fastening
anchor manufacturer.
DANGER
Risk of death from electric shock.

All poles of the power cable must be disconnected
from the power grid by an lockable external switch.
