1 Safety

Warning!

Suspending any object is potentially dangerous and should only be attempted by individuals

who have thorough knowledge of the techniques and regulations of suspending objects

overhead. Bosch strongly recommends all loudspeakers be suspended taking into account all

current national, federal, state, and local laws and regulations. It is the responsibility of the

installer to ensure all loudspeakers are safely installed in accordance with all such

requirements. When loudspeakers are suspended, Bosch strongly recommends the system be

inspected at least once per year or as laws and regulations require. If any sign of weakness or

damage is detected, remedial action should be taken immediately. The user is responsible for

making sure the wall, ceiling, or structure is capable of supporting all objects suspended

overhead. Any hardware used to suspend a loudspeaker not associated with Bosch is the

responsibility of others.

Suspension Cable Important Safety Instructions:

Load - Do not exceed the WLL (Working Load Limit) of the pendant suspension cable.

The WLL of the pendant suspension cable is 10 kg (22 lb).

No lifting - Do not use for lifting, such as in a crane or pulley situation.

No movement - The pendent suspension cable is to be used to suspend static loads only. Do not

use the cable to suspend moving objects or objects likely to be subject to

movement.

No joining - Do not splice together the pendent suspension cable with another cable or

other joining device. The pendent suspension cable as supplied is the maximum

length available and should not be altered in any way.

Not for re-use - Do not re-use the pendent suspension cable; it is designed for permanent fixed

installation use only.

Lubricants - Do not apply oil or any other lubricant to any part of the assembly.

Round duct/pipes - When wrapping around duct or other round pipes, do not exceed an angle of 60

degrees between the top of the pipe and the pendent suspension cable.

I-Beams - Minimum radius on I-Beams to be no less than 1/8-inch.

Corners/edges - Cables in contact with corners, edges, protrusions, or abrasive surfaces shall be

protected with a material of sufficient strength, thickness, and construction to

prevent damage.
