2.7 Ingress Protection Ratings
The product is rated for ingress Protection as follows:
IP rating
per EN60529: IP66
Type rating per UL50E / NEMA250: 4 / 4X / 3R / 13
Suitable for exposure to Acetone , Ammonium Hydroxide ,
Diethyl Ether , Ethyl Acetate , Ethylene Dichloride , Furfural,
n-hexane , Methyl Ethyl Ketone , Methanol , 2-NitroPropane
and Toluene.
To maintain the ingress protection rating, the cable entries
must be fitted with suitably rated, certified cable entry and/or
blanking devices during installation.
2.8 Electrical Ratings
#Rated at 1Hz
Table 1: Electrical Ratings
It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the units.
The input current will vary according to the voltage input level.
3) Special Conditions of Use
The enclosure coating is non-conductive and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be
subjected to external conditions (such as high pressure steam)
which might cause a build-up of electrostatic charges on non-
conducting surfaces. Additionally, cleaning of the equipment
should be done only with a damp cloth.
Flame Path Positions
4) Installation
There are no restrictions on unit orientation.
The junction box must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive
atmospheres - Classification of areas. Explosive gas
atmospheres
EN60079-10-2 / IEC60079-10-2: Explosive
atmospheres - Classification of areas. Explosive dust
atmospheres
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried out
by a competent electrical engineer who has the necessary
training.
4.1 Safe Installation Requirements
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably
certified 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 certified
for the application. Fitting of blanking elements into adaptors
is not permitted.
Check that the ‘O’ ring seal is in place before replacing the
explosionproof cover.
Lens guard must be fitted for Class Division installations.
5) Location and Mounting
The location of the beacon should be made with due regard to
the area over which the warning signal must be visible. It
should only be fixed to services that can carry the weight of the
unit.
The D1xB2X beacon can be mounted using one of three
methods.

1. The beacon can be surface mounted by removing,
rotating and reinstalling the stowed mounting lugs. These
are suitable for 6mm diameter fixings.
a. Remove 2 x M5 fasteners per
mounting lug
b. Reverse and rotate lug and
reseat onto enclosure
c. Secure lug using the 2 x M5
Fasteners
2. Alternatively, the beacon can be conduit mounted using
the 3/4” NPT entry on the base of the unit.
3. Additionally, the beacon can be mounted using the ratchet
adjustable stainless-steel wall bracket assembly. This is
available as an accessory – part code: SP77-0001.
Fig. 1 Fixing Location for Beacon
6) Access to the Enclosure
In order to connect the electrical supply cables to the beacon,
it is necessary to open the explosion proof enclosure. Loosen
the locking grub screw in the cover and then remove the
glass dome cover assembly to gain access to the chamber.
This can be achieved by unscrewing the glass dome cover,
taking extreme care not to damage the threads when doing
so.
Fig. 2 Accessing the Enclosure.
On completion of the installation the flameproof threads should
be inspected to ensure that they are clean and that they have
not been damaged during installation. Ensure the O-ring seal
is in place and undamaged.
When fitting the flameproof cover ensure the thread is
engaged correctly. Fully tighten the cover all the way, ensure
no gap is visible between the cover and base of the beacon
enclosure.
7) 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 section 11), the
number of beacons 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 beacons connected to the
line.
The entries are 2-off M20 x 1.5 thread & 3-off ¾” NPT thread
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.
NPT plugs should be greased before insertion.
For high ambient temperatures the cable entry temperature
or the cable branching point temperature may exceed 60ºC
and therefore suitable heat resisting cables and cable glands
must be used, with a rated service temperature of at least the
values stated below:
Table 2: Required Cable/Cable Gland Ratings (°C).
8) Cable Connections
The units have 2-off M20 x 1.5 threaded entries and 3-off ¾”
NPT x 14 threaded entries.
Electrical Connections are to be made into the terminal blocks
using solid or stranded wire, sizes 0.5-2.5mm2 / AWG 20-14.
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.
See section 5 of this manual for access to the enclosure.

Warning – High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.
Warning –

9.1 Line Monitoring
On the D2xB1X unit, DC reverse line monitoring can be used
if required.
All DC beacons have a blocking diode fitted in their supply
input lines. An end of line monitoring resistor can be connected
across the +ve and –ve terminals in the explosion proof
enclosure. If an end of line resistor is used it must have the
following values:
Minimum resistance 3K3 Ohms Minimum Power 0.5W
Minimum resistance 500 Ohms Minimum Power 2.0W
The resistor must be connected directly across the +ve and
-ve terminals as shown in the following drawing. Form the
resistor legs as shown in Fig. 5a, fit the resistor across the two
terminals, as shown in Fig. 5b.
Fig. 5a End of Line Resistor Forming
Fig. 5b End of Line Resistor Placement
10) Earthing
The unit has an external and an internal earth terminal, (please
see fig 6).
Please note that for AC supply voltage product versions the
Earth terminal on the PCBA does not provide an earth
connection to the product enclosure. The enclosure must be
independently earthed using either the external or internal
earth fixing point, (see fig 6 and notes below).
Internal earthing connections should be made to the internal
Earth terminal in the base of the housing using a ring crimped
terminal to secure the earth conductor under the earth clamp.
The earth conductor should be at least equal in size and rating
to the incoming power conductors.
External earthing connections should be made to the M5 earth
stud, using a ring crimp terminal to secure the earth conductor
to the earth stud. The external earth conductor should be at
least 4mm” in size.
