Neumann.Berlin LH 47 Mounting Manual

Important safety and mounting instructions

• Have the product mounted by a specialist.
• Due to his/her technical training, know-how and experience as well
as knowledge of relevant provisions, regulations and standards, the
specialist must be able to assess assigned tasks, recognize poten-
tial hazards and ensure appropriate safety measures. The following
safety and mounting instructions are addressed to this specialist.
• Read and follow the safety and mounting instructions, keep these
instructions and always include them when passing the LH 47 on
to third parties.
• Also read and follow the installation instructions contained in the
operating manual of the mounted loudspeaker.
• When mounting, observe and follow the local, national and interna-
tional regulations and standards.
• Only mount loudspeakers in combination with other accessories from
the Neumann mounting hardware range to the LH 47 (see below).
• Only mount one loudspeaker with a maximum weight of 65 kg
(143.3 lbs) to the LH 47.
• Do not install the LH 47 in locations where it is exposed to externally
generated vibrations.
• Always use the original supplied parts.
In the following you will be asked to combine other acces-
sories from the Neumann mounting hardware range with the
LH 47. Download the PDF file "Hardware Mounting Matrix"
from www.neumann.com. Only combine the Neumann moun-
ting hardware as specified in the "Hardware Mounting Matrix".
• First attach a Neumann mounting hardware that features a cylinder-
shaped holder (e.g. LH 43, 45, 46) to a vertical or horizontal surface.
Follow the safety and mounting instructions contained in the operat-
ing manual of the selected mounting hardware.
Horizontal surfaces must be able to carry the weight of all parts
used plus the weight of the loudspeaker. With vertical surfaces,
you additionally have to consider the leverage.
• Fasten your loudspeaker to a Neumann mounting hardware that is
also suitable for mounting to the LH 47 (e.g. LH 25, LH 42, LH 61, refer
to the "Hardware Mounting Matrix"). Follow the safety and mount-
ing instructions contained in the operating manual of the selected
mounting hardware.
• Next attach the LH 47 to the mounting hardware/loudspeaker
combination (see fi . 1).
– If di erent mounting positions are possible, choose mounting
points that minimize leverage when the loudspeaker is tilted.
– Tighten the nuts with a torque of 20 Nm.
• Now mount the LH 47 onto the cylinder-shaped holder
Neumann mounting hardware. To do so, proceed as shown in fi . 2.
CAUTION!
Danger of injury and material damage
due to dropping of the loudspeaker
Unless the LH 47 is properly fastened to the cylinder-shaped
holder, the loudspeaker together with the mounting hardware
can drop down.
Have the loudspeaker held by a second specialist who is
X
physically able to do so. The requirements mentioned ear-
lier also apply to this specialist.
When mounting the loudspeaker, provide a sufficien addi-
X
tional protection against dropping.
