Note
Prior to installing the Loudspeaker,
these operating instructions must be
read care-fully.
pplication
The loudspeaker with built-in 100 V
transformer can be connected to 100 V
loudspeaker systems according to VDE
0800 T1: 5.89. ll outer fas tening parts
have been made of non-corrosive mate-
rials. The stable, electrically conductive
all-plastic housing conforms to protection
degree IP 66, which means the loud -
speaker can be installed both inside and
outside. Depending on version / model,
two optional connections are available:
– Protection class I: equipped with a
metal accommodation for cable glands
and entries with armoured cable or
Conduit-Systems
– Protection class II: equipped with
plastic cable glands and entries.
Mounting and Connection
The loudspeaker is suited for wall and
ceiling mounting. For mounting dimen-
sions, see the dimension illustration (on
page 1). The wall bracket that comes
with the loudspeaker is fastened with 2
screws (Ø 6 or 8 mm). To connect loosen
the lid screw and remove the lid. The
captive lid is held by a tensile strength
reducer.
Installation
Prior to leading the connecting loud -
speaker cable through the cable gland,
100 –130 mm of the isolation must be
removed. Within the loudspeaker, the
cable
gland
must
close
around the end of the connecting cable's
outer isolation. Remove 8 to 10 mm of
the isolation from the conductors of this
cable, and connect the conductors to
the terminals 1 and 2. You may choose
which side to connect. Terminal blocks
1 and 2 are interconnected by a jumper.
See fig. 1. Loudspeakers models of
protection class I must be connected to
earth. For this purpose, there are marked
terminals both inside the device and on
the outer casing. If the cable glands are
installed by the loudspeaker user, the
instructions of the cable gland manufac-
turer must be observed. Ensure that the
external thread of the cable gland is
equipped with a sealing tape in order to
guarantee the protection type (IP) of the
device. If the sealing rings of a cable
gland are fastened with a torque excee-
ding 20 Nm, measures must be taken
on the loudspeaker side to secure the
cable gland against over-tightening.
Upon installing several loudspeakers in
one room, great care must be taken to
achieve correct polarity of the connecting
cable, i.e. all terminal connections No. 1
must be connected to each other, as
must all terminal connections No. 2.
Upon connecting several loudspeakers
in a series, the maximum rated power
should not exceed 500 W. Use suffi-
ciently long cables to facilitate positio-
ning of the loudspeakers.
djusting the volume
In the factory, the rated power of the
loudspeaker is set to its maximum. The
volume can be adjusted by means of
the two code cables (yellow/brown)
between the common terminals. Cable
coding and rated power, see Table 1.
Wiring within the loudspeaker
fter connecting the loudspeaker, place
the single conductors of the connecting
cables flatly across the common termi-
nals, in the direction of the cable gland.
Warning! To avoid the danger of the
conductors being squeezed, they should
not be laid across the threaded lid bolt
or the edge of the seal.
Close the lid
Put the lid on. Make sure that the lid sits
straight and that the "lid fastener" has
not been placed across neither the
threaded lid bolt nor the sealing edge nor
the terminals. Then turn the lid screw as
far as it goes, and tighten lightly.
Position the loudspeaker
If the loudspeaker is connected to
flexible cables, following installation it
may be turned in the desired position.
Tighten both side screws of the wall
bracket. If the loudspeaker is connected
with Conduit or armoured cable, align-

the installation procedure, to ensure that
the connection is not subjected to
mechanical strain.
Operating utilization position
In order to avoid a reduction of the volume
due to dust, rain water or other foreign
matter, the horn should be mounted
horizontally or vertically, facing down-
wards.
Maintenance
The loudspeaker is maintenance-free.
Nevertheless in case of dirtiness it
should be cleaned from time to time
with a damp cleaning cloth. Never use
sharp objects for cleaning.
Waste Disposal
The loudspeaker may be completely
recycled as electronic waste. Upon
disassembling, the plastic, metal and
electronic components must be disposed
of separately. In every single case the
national requirements and regulations
for waste disposal must be observed.
EM -Directive
The device complies with the requirements
of the new EMC-directive 2004/108/EC
and the low voltage directive 2006/95/EC.
The conformity with the above directives
is confirmed by the CE sign.
