large bracket adjustment screws on the side of the unit must
be fully tightened to ensure that the unit cannot move in
service.

5) Access to the Enclosure
To access the enclosure, remove the four M4 posi pan head
screws, M4 spring and plain washers and withdraw the cover.
Fig. 2 Accessing the Enclosure.
To replace cover, c
heck that the ‘O’ ring seal is in place.
Carefully push the cover in place. Insert and tighten down M4
screws, spring and plain washers in the order shown above
and tighten down.
6) Selection of Cable, Cable Glands, Blanking
Elements & Adapters
When selecting the cable size, consideration must be given
to the input current that each unit draws (see Table 1), the
number of sounders on the line and the length of the cable
runs. The cable size selected must have the necessary
capacity to provide the input current to all of the sounders
connected to the line.
The dual entries can be ordered with one of the following
options:
2-off M20 x 1.5 thread
2-
off ½” NPT thread
1-off M20 x 1.5 & 1-
off ½” NPT thread
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated,
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
For ambient temperatures over +40ºC the cable entry
temperature may exceed +70ºC or the cable branching
temperature may exceed +80ºC. Therefore suitable heat
resisting cables and cable glands must be used as per table
below

40ºC
45ºC
50ºC
55ºC

and cable glands

100ºC
105ºC
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs.
For use in explosive dust atmospheres, a minimum ingress
protection rating of IP6X must be maintained.
For use in explosive gas atmospheres, a minimum ingress
protection rating of IP54 must be maintained.
7) Cable Connections
The E2xC1LD2 combined sounder beacon has separate
printed circuit boards in the sounder and beacon sections.
The terminals for the sounder are on the printed circuit board
in the sounder section and the terminals for the beacon are
on the printed circuit board in the beacon section (see figures
4a, 4b, 6a and 6b). See section 5 of this manual for access to
the enclosure. See section 9 and 10 for AC and DC wiring
diagrams respectively. Electrical connections are to be made
into the terminal blocks on the PCBA located in the
enclosure. See section 5 of this manual for access to the
enclosure.
Wires having a cross sectional area between 0.5 mm² to
2.5mm² can be connected to each terminal way. If an input
and output wire is required the 2-off Live/Neutral or +/-
terminals can be used. If fitting 2-off wires to one terminal
way the sum of the 2-off wires must be a maximum cross
sectional area of 2.5mm². Strip wires to 8mm. Wires may also
be fitted using ferrules. Terminal screws on the sounder
PCBA need to be tightened down with a tightening torque of
0.45 Nm / 4 Lb-in. Terminal screws on the beacon PCBA
need to be tightened down with a tightening torque of 0.56
Nm / 5 Lb-in. When connecting wires to the terminals great
Warning
–
Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
Warning
– High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.
