페이지 인쇄The Equipment must not be installed with the horn facing
upwards of horizontal.
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably
rated cable entry and/or blanking devices during installation.
If conduit is used for installation, seal conduit within 18
inches from the enclosure.
If entries are fitted with adaptors they must be suitably rated
for the application. Fitting of blanking elements into
adaptors is not permitted.
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer or O-ring must be fitted under any
cable gland or blanking device with metric threads.
Only the explosionproof cover is to be used for access to
the enclosure for installation, service and maintenance.
Connections are to be made into the terminal blocks using
solid or stranded wire, sizes 0.5–2.5mm
Wire insulation needs to be stripped 6–7mm. Wires may be
fitted securely with crimped ferrules. Terminal screws need
to be tightened down with a tightening torque of 0.4 Nm / 3.5
Lb-in.
Earthing connections should be made to the Internal Earth
terminal in the explosionproof chamber or the external
earth stud.
Check that the O-ring seal is in place before replacing the
explosionproof cover.
4.2 Mounting
Figure 1
. Fixing locations
13310-3xx Loudspeakers should only be installed by trained
competent personnel.
The Loudspeakers may be secured to any flat surface using
the three 7mm fixing holes. The enclosure provides IP66
protection and is suitable for indoor and outdoor use
providing it is positioned so that water cannot collect in the
horn, and the cable entry is sealed.
4.3 Installation Procedure
a. Secure the Loudspeaker to a flat surface via the three
7mm fixing holes in the mounting bracket.
b. Remove the explosionproof cover of the loudspeaker by
unscrewing it, taking care not to damage the threads in
the process. (Refer to Section 5.)
c. Fit an M20x1.5 suitably certified cable gland or ½" NPT
conduit into the corresponding entry in the enclosure and
connect the field wiring to the appropriate loudspeaker
terminals as shown in Section 6 / Figure 3 (70V Line In)
or Section 7 / Figure 4 (Low Impedance) of this manual.
The power supply terminals on the low impedance units
are duplicated so that units may be connected in parallel.
An end-of-line monitoring resistor may be fitted to either
type of unit. Additional entries which are not used must
always be fitted with suitably certified blanking elements.

d. Replace the explosionproof cover of the loudspeaker,
taking care not to damage the explosionproof threads and
checking that the O-ring seal is in place. Tighten the cover
fully.
4.4 Hornless Variants
The 13310-3xx Loudspeaker is also available as a variant
with no horn fitted in the factory. The Horn threaded nose
portion has a fitment thread of 1-3/8" – 18 UNF (to BS1580
or ANSI B1.1). The customer is responsible for sourcing
and correctly fitting a suitable horn that meets all of the
relevant safety requirements.

Access to the Explosionproof Enclosure
In order to connect the electrical supply cables to the
loudspeaker, it is necessary to remove the explosionproof
cover to gain access to the explosionproof chamber. This
can be achieved by unscrewing the explosionproof cover,
taking extreme care not to damage the explosionproof
threads in the process.

Figure 2. Accessing the Explosionproof Enclosure
On completion of the cable wiring installation the explosionproof
threads should be inspected to ensure that they are clean and
that they have not been damaged during installation. Also check
that the O-ring seal is in place on the thread diameter in contact
with the flat face of the explosionproof cover. When replacing
the explosionproof cover ensure that it is tightened fully.
