Mounting manual
• Mount the loudspeaker plus additionally attached hardware to the
cylinder-shaped holder B of the LH 45. To do so, proceed as shown
in figs. 3 to 7:
CAUTION
Danger of injury and material damage
due to dropping of the loudspeaker!
Unless the additional hardware is properly fastened to the cyl-
inder-shaped holder B of the LH 45, 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 earlier
also apply to this specialist.
When mounting the loudspeaker, provide a sufficien addi-
X
tional protection against dropping.
– Position the locking ring of the cylinder-shaped holder
upper position and tighten one of the 4 Allen screws so that the
locking ring cannot work loose and fall off.
– Place the loudspeaker plus additionally attached hardware onto
the cylinder-shaped holder
– Loosen the previously tightened Allen screw
ring C (see fi . 6).
– Lower the locking ring into position (see fi . 7).
– Rotate the loudspeaker in the desired direction.
– Tighten the 4 Allen screws with a torque of 15 Nm. The loud-
speaker with attached additional hardware is now properly fas-
tened to the cylinder-shaped holder 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
the attached loudspeaker and mounting hardware.
• If necessary, vertically tilt the loudspeaker to the desired angle.
• Make sure that ...
– the LH 45, the associated mounting hardware and the loudspeaker
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 LH 45 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 LH 45 and
the additional mounting hardware used.
