Suspended Installation
●
The strength of the suspension points on the speaker is
60 kg
per
point (maximum).
● Before doing any installation or construction work, consult with an
installation expert.
● When choosing the installation location, suspension wire and
mounting hardware, make sure all are strong enough to support the
weight of the speaker.
●
Some fittings may deteriorate over extended periods of time due to
wear and or corrosion. For optimum safety, the installation should be
checked thoroughly at regular intervals.
■ Using eye bolts for suspension
For optimum safety, make sure to carefully follow the
precautions below.
●
Use only the supplied eye bolts.
●
Use three or more eye bolts for suspended installations.
●
Use the optional array frame if you intend to suspend a speaker from
another suspended speaker.
●
Install the eye bolts to multiple surfaces of the speaker, not just one
surface.
■ Eye bolt strength
Keep in mind that the strength of the eye bolt differs depending
on the suspension angle of the speaker. Make sure that the
load for each eye bolt is less than 740 kg when suspending at
an angle of 0 degrees, and less than 185 kg at an angle of 45
degrees.
When using the eye bolts,
make sure that the suspension
angle is within the range of 0
to 45 degrees, as shown at
right.
Do not suspend the eye bolts
as shown in the diagram at
right.
Rotatable horn
(IF3115, IH2000 only)
1.
Remove all fixing screws on the grille, and remove the grille
from the speaker.
2.
Remove all screws installed on the horn, pull out the horn
from the speaker, rotate the horn 90 degrees, and re-install
the horn to the speaker.
Be careful when rotating the horn so that you do not accidentally cut the
