Overhead Installation
If the speaker is to be installed with a mounting height of more than 1 meter (e.g. on a
stage or framework), the speaker must always be secured with an appropriate secondary
securing attachment.
The installation must always be secured with a secondary safety attachment. e.g. an appropriate
catch net. The secondary safety attachment must be constructed in a way that no part of the
installation can fall down if the main attachment fails.
When rigging, derigging, or servicing the speaker standing in the area below the
installation place, on bridges or other endangered areas are forbidden.
The operator has to make sure that the safety data is approved by an expert before operation for
the first time and after any changes are made.
The operator has to make sure that the safety data is approved by an expert after every four years
in the course of an acceptance test.
The operator has to make sure that the safety installation data is approved by a skilled person once
a year.
Procedure
The speaker should be installed outside areas where persons may walk by or seated.
IMPORTANT! OVER HEAD RIGGING REQUIRES EXTENSIVE EXPERIENCE,
including (but not
limited to) calculating working limits, installation materials used, and periodic safety inspection of all
installation materials and the speaker. If you lack these qualifications, do not attempt the installation
yourself, but instead use a professional structural rigger. Improper installation can result in bodily
injury and damage to your property.
The speaker has to be installed out of the reach of people.
CAUTION:
Speakers in overhead installations may cause severe injuries when falling! If you have
doubts concerning the safety of a possible installation, do not install the speaker!
Before rigging make sure that the installation area can hold a minimum point load of 10 times the
speakers weight.
