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 buildup 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 ¾”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.
Warning –High voltage may be present,
risk of electric shock. DO NOT open when
energised, disconnect power before
opening.
Warning –Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.

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:
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.
9) Wiring
A 4-way terminal block is provided on the DC beacons for
power. There are 2-off +ve, 2-off –ve terminal and an internal
Earth boss.

9.2 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. 7a, fit the resistor across the
two terminals, as shown in Fig. 7b.

Fig. 7b End of Line Resistor Placement
10) Earthing
The unit has an external and an internal earth terminal,
(please see fig 8).
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.
