INSTALLATION INSTRUCTIONS
AH5040CD INSTALLATION
INSTALLATION VIA MOUNTING BRACKET (INCLUDED)
General considerations and hardware recommendations
CAUTION: The AH5040CD weights 81 pounds (36.7kg). A fall from almost any height could result in
serious injury or death. Assure that the speaker is firmly mounted to an object that can handle the weight
of the AH5040CD. Remember that wind will add considerable torque to the point of attachment. The
mounting surface the AH5040CD is being attached to should be able to handle five or more times the
weight of the AH5040CD (7x recommended for locations subject to high wind forces).
Whenever the loudspeaker is mounted to a surface using the bracket, the installer must ensure that the
surface is capable of safely and securely supporting the load. The hardware employed must be safely
and securely attached both to the loudspeaker and the surface in question, using only the mounting
holes. A general rule for soft surface installations (wood beams) is to multiply the corresponding working
load limit by 75%: the result will be an approximation of working load strength.
Use thread locking compound for all installations.
CAUTION: Mount the speaker such that the shear force is at a right angle to the mounting bolts, and
close to the connection, as shown:
When mounting the AH5040CD to a solid surface use the proper bolts, washers and lock washers
(Grade 5 minimum). Do not substitute mismatched bolts and washers.
The AH5040CD may be mounted to a pole or scoreboard. For such mounting, contact the light pole or
scoreboard manufacturer for proper instructions.
If mounting to another surface, such as a beam, see the diagram on page 7 for mounting hole locations.
When in doubt contact a qualified structural/mechanical engineer for approval of the mounting
materials and methods.
