DANGER
Assembly by qualified personnel
►
Assembly must be done by qualified personnel only.
Lack of appropriate knowledge may pose a death
hazard.
►
Two people are needed for assembly.
DANGER
Death hazard from falling luminaire.
►
The ceiling mount must only be mounted on ceilings
with a concrete stability class of B25 (C20/25) or
higher.
►
There should be no contact with reinforcement parts
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 and in
compliance 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 structural engineer must be consulted.
►
Install the luminaire such that the vertical stops are
not continuously stressed during operation.
►
With plaster or cladding in front of concrete, the fas-
tening 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
Death hazard from electric shock.
►
All poles of the power cable must be disconnected
from the power grid from an external lockable switch.
