RIGGING
Important: The installation must be carried out by qualified service personal only. Improper
installation can result in serious injuries and/or damage to property. Overhead rigging requires
extensive experience! Working load limits should be respected, certified installation materials
should be used, the installed device should be inspected regularly for safety.
Make sure the area below the installation place is free from unwanted persons during rigging, de-rigging
and servicing.
The cabinet should be installed out of reach of people and outside areas where persons may walk by or
be seated.
Before rigging make sure that the installation area can hold a minimum point load of 10times the
cabinet
’s weight.
Always use a certified safety cable that can hold 12 times the weight of the cabinet while installing the
unit. This secondary safety attachment should be installed in a way that no part of the installation can
drop more than 20cm if the main attachment fails.
The cabinet should be well fixed; a free-swinging mounting is dangerous and may not be considered!
The operator has to make sure that the safety-relating and machine-technical installations are approved
by an expert before using them for the first time. The installations should be inspected every year by a
skilled person to be sure that safety is still optimal.
The PSA-cabinets have 4 rigging points using M8 inserts.
These can be used to suspend (fly) the cabinet in the air.
For this purpose you can use heavy duty eyebolts with
metric M8 thread. In most cases 2 cables will be attached to
the top and one is used to pull up the back.
Anyway always take special care when the cabinets are
suspended. This is potentially dangerous and should only
be carried out by technicians who have perfect knowledge
of the techniques and regulations of rigging speakers!
