Note
Prior to installing the Loudspeaker, these
operating instructions must be read carefully.
pplication
The loudspeaker with built-in 100 V trans-
former can be connected to 100 V loud -
speaker systems.
ll outer fas tening parts
have been made of non-corrosive materials.
The stable, electrically conductive all-plastic
housing conforms to protection degree
IP 66, which means the loudspeaker can be
installed both inside and outside. Explosion
protection class allows the loudspeaker to
be operated in Ex areas of the zones 1 and 2.
Depending on version / model, two optional
connections are available:
– Protection class I: equipped with a metal
accommodation for cable glands and
entries (KLE) 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 dimensions, 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 loudspeaker
cable through the cable gland, 100–130 mm
of the isolation must be removed. Within
the loudspeaker, the cable gland must clo-
se smoothly around the end of the connec-
ting 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 loud-
speaker user, the instructions of the cable
gland manufacturer must be observed.
Only
TEX-certified cable glands may be
used. 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
exceeding 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 con-
nected to each other, as must all terminal
connections No. 2. Upon connecting seve-
ral loudspeakers in a series, the maximum
rated power should not exceed 500 W. This
means that if the rated power of each loud-
speaker is for example 15 W, a maximum
of 33 loudspeakers may be connected.
Use sufficiently long cables to facilitate
positioning of the loudspeakers.
djusting the volume
In the factory, the loudspeaker's rated
power has been 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 terminals, in the
direction of the cable gland.
Warning! To avoid the danger of the con-
ductors 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 the lid sits
straight, and that the „lid fastener" has not
been placed across the threaded lid bolt or
across the sealing edge. 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 tur-
ned in the desired position. Tighten both
side screws of the wall bracket. If the loud-
speaker is connected with Conduit or
armoured cable, alignment must follow
during the first step of the installation pro-
cedure, 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 hori-
zontally or vertically, facing downwards.
Maintenance
The
loudspeaker
is
Never theless 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 compo-
nents 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.
