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

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.

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, 61, refer LH

to the Hardware Mounting Matrix ). Follow the safety and mount“ ” -

ing instructions contained in the operating manual of the selected

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

holder, the loudspeaker together with the mounting hardware

can drop down.

Use safety wires to additionally protect the loudspeaker and the

mounting hardware against dropping. The safety wires, rope ter-

minations 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 dropping of a load

of 65 kg (143.3 lbs).
