1. In addition to the fast and safe EPS connection from the
I-Bracket to the loudspeaker, the connection can also be
tightened without backlash. To achieve this, the distance
between the EPS Lock Pins and the inside of the EPS
Rigging Point is shortened by tightening the M6 DIN 912
screw. In order to insert and lock the EPS into the EPS
Rigging Points, the EPS must be in a released state
(Delivery State). If this state is needed to be reached or
if you want to check it, use a ratchet with with a HEX
BIT Number 5 (Wrench Size 5mm) or use your fingers to
loosen the M6 DIN 912 screw a bit by turning it $4'2,

1. Mount the I-Bracket to the ceiling. Use an M12 roof
anchor and an M12 self-locking nut for the central
mounting hole. Optionally, you can use an M10 roof
anchor and an M10 self-locking nut for the semicircular
oblong holes to further fix the loudspeaker's rotational
position. Do not tighten the nuts until the final position
of the loudspeaker assembly has been reached, but make
sure that the I-Bracket cannot fall down during the
mounting procedure! Alternatively, mount the I-Bracket
to the loudspeaker first and then to the ceiling.
2. Check if the I-Bracket can be rotated easily when you
turn it to the left or the right. (Roof anchors are not
shown in the further depictions). If using the M12 roof
anchor only, the I-Bracket can be rotated by 360 degrees.
If using the additional M10 roof anchor, the I-Bracket can
be rotated by +/- 45 degrees from its center position.

for the installation. Anchor the roof anchors firmly and safely!

The assembly procedure of the I-Bracket Short shown in this chapter is corresponding to the procedure of I-Bracket Long and
always follows the same scheme.
•First mount the I-Bracket to the Ceiling
Adapter by inserting the M12 DIN 7991 screw
through the central hole and locking it with
the self-locking M12 nut. Make sure that the
I-Bracket rotates easily, but allows as little
backlash as possible. Adding some grease can
help to rotate it more easily.
•In the next step the M10 DIN 912 screw and
an M10 washer should be inserted. The I-
Bracket can be rotated by +/- 45 degrees
from its center position.
•Check if the I-Bracket can be rotated easily to
the left or the right. Tighten the M10 screw to
fix the desired rotational position.
•The I-Bracket can also be used in a 90 degrees
rotated position on the Ceiling Adapter. To do
this, you need to reposition the M10 screw.
