LH 28 Mounting manual
Tripod Stand Adaptor
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 28 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.
•
Mount the LH 28 in combination with other accessories from the
Neumann mounting hardware range to loudspeakers with a maxi-
mum weight of 65 kg (143.3 lbs).
•
The LH28 is suitable for suspended mounting. The locking not
screw B protects the LH 28 from rotating, but does not provide
su cient protection against tensile stress. Only use the LH28 for
mounting on loudspeaker stands or subwoofers as shown in fi g. 4.
•
Do not install the LH 28 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
LH28. Download the PDF fi le “Hardware Mounting Matrix”
from www.neumann.com. Only combine the Neumann moun-
ting hardware as specifi ed in the “Hardware Mounting Matrix”.
•
Fasten your loudspeaker to a Neumann mounting hardware that is
also suitable for mounting to the LH28 (e.g. LH 25, LH36, LH61,
refer to the ). Follow the safety and “Hardware Mounting Matrix”
mounting instructions contained in the operating manual of the
selected mounting hardware.
• Attach the LH 28 to the mounting hardware/loudspeaker combina-
tion (see fi g. 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 20Nm.
•
Loosen the locking screw on the LH28 so that the LH28 can be B
fully slid onto a tripod stand.
CAUTION!
Danger of injury and material damage
due to dropping of the loudspeaker
Unless the LH 28 is properly fastened, the loudspeaker together
with the mounting hardware can drop down.
Have the loudspeaker held by a second specialist who is
physically able to do so. The requirements mentioned earlier
also apply to this specialist.
When mounting the loudspeaker, provide a su cient addi-
tional protection against dropping.
•
Slide the LH28 with the mounted loudspeaker as far as it will go
onto a tripod stand with a tube diameter of 35mm (1 . ⅜”)
You can also use the LH28 for mounting a loudspeaker onto
a Neumann subwoofer (see fi g. 4). For this, you require a
distance rod (to be ordered separately) with the following
characteristics:
• diameter: 35mm (1⅜”);
• as short as possible to minimize leverage;
• manufacturer-rated for the weight that is to be supported.
First slide the distance rod into the subwoofer‘s mounting
fl ange, then slide the LH28 onto the distance rod.
• Tighten the locking screw .B
•
Use safety wires to additionally protect the loudspeaker and the
mounting hardware against tipping/dropping. The safety wires, rope
terminations and coupling links must comply in their dimensioning
and condition with the regulations and standards of the country in
which they are used and must reliably prevent tipping/dropping of
a load of 65 kg (143.3 lbs; when mounting the loudspeaker onto
a subwoofer, you have to add the weight of the loudspeaker and the
mounting hardware).
• Make sure that ...
–
you use both screws D to fasten the LH 28 to suitable Neumann
mounting hardware;
–
the LH 28, the associated mounting hardware, the loudspeaker
and the tripod stand cannot tip over or drop down, even if the
power or audio cables are pulled;
–
you replace the safety wires and coupling links by new ones when
they have prevented tipping/dropping;
–
you check every 3 months if all screws are properly tightened
and if the LH28 and associated mounting hardware, additional
fastening elements, safety wires and coupling links, as well as the
loudspeaker are in proper condition.
In case of any damage or any deviation from the safety and mounting
instructions, immediately dismount the loudspeaker, the LH28 and the
additional mounting hardware used.
