5) Special Conditions for Safe Use
Repair of the flame path / flameproof joints is not permitted.
Figure 1: Flame Path.
The metallic enclosure has a non-conductive coating. These
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 that might cause a build-up of
electrostatic charges on non-conducting surfaces.
6) Product Mounting and Access
6.1. Location and Mounting
The location of the beacons should be made with due regard
to the area over which the warning signal must be visible. They
should only be fixed to services that can carry the weight of the
unit.
STExB2X21 models shall not be mounted with the lamp down.
The STEx beacons should be securely bolted to a flat surface
using 9.0mm diameter bolt holes in the base of the unit. See
figure 2.
Figure 2: Fixing Location for B2 Beacon.
6.2. Access to the Flameproof Enclosure
Warning –Hot surfaces. External
surfaces and internal components
may be hot after operation, take
care when handling the equipment.
In order to connect the electrical supply cables to the beacon
it is necessary to remove the flameproof cover to gain access
to the flameproof chamber. To access the Ex d chamber,
loosen the M4 grub screw on the beacon cover. Open the
enclosure by turning the beacon cover counterclockwise and
remove the cover, taking extreme care not to damage the
flameproof threads in the process (See figure 3).
Figure 3: Accessing the Explosion Proof Enclosure.
On completion of the installation, the flameproof threaded joint
should be inspected to ensure that they are clean and that they
have not been damaged during installation.
Repair of the flame path / flameproof joints is not permitted.
Ensure that the ‘O’ ring seal is in place.
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. Tighten the M4 grub screw.
7) Installation Requirements
7.1. Installation Standards Compliance
Warning –High voltage may be
present, risk of electric shock.
DO NOT open when energised,
disconnect power before opening.
The beacon must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards.
ATEX / IECEx installation standards:

Electrical installations design, selection and erection.
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -

NEC Class / Zone, CEC Class / Zone, and NEC & CEC Class
/ Division installation standards:
National Electrical Code, NFPA 70 or CSA 22.1 Canadian
Electrical Code, Part I, Safety Standard for Electrical
Installations, Section 32.
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.
7.2. Cable Selection and Connections
When selecting the cable size, consideration must be given to
the input current that each unit draws (see table 1), 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.
Electrical connections are to be made into the terminal blocks
on the PCBA, using solid wire 0.5-4mm2 / AWG 20-12 or
stranded wire, sizes 0.5-2.5mm2 / AWG 24-14. Wire insulation
needs to be stripped 8mm. Wires may be fitted securely with
crimped ferrules.
Figure 4: Wire Preparation.
Terminal screws need to be tightened down with a tightening
torque of 0.45 Nm / 5 Lb-in. A 5-way terminal block is provided
on the AC Beacon: 2-off Live, 2-off Neutral and 1-off Earth
terminals in total. A 4-way terminal block is provided on the DC
Beacon: 2-off +ve and 2-off -ve terminals.
Figure 5: STExB2 Entries and Terminal Block Location.
When connecting wires to the terminals great care should be
taken to dress the wires so that when the cover is inserted into
the chamber the wires do not exert excess pressure on the
terminal blocks. This is particularly important when using
cables with large cross-sectional areas such as 2.5mm².
Earthing
Internal earthing connections should be made to the Internal
Earth terminal in the base of the housing using a ring crimp
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 4mm2 in size.
7.3. Cable Glands, Blanking Elements & Adapters
For high ambient temperatures, the cable entry and the cable
branching point temperatures may exceed the following
temperatures:
•For ATEX / IECEx: 70ºC at entry or 80ºC at branching point.
•For NEC / CEC: 60ºC at entry or 60ºC at branching point.
Therefore, suitable heat resisting cables and cable glands
must be used, with a rated service temperature at least as
stated in the table below:

Table 2: Min. Ratings of Cables & Cable Glands.
Cable Glands
The cable gland entries have an M20 x 1.5 entry thread. Only
use suitably rated and certified cable glands, as per type of
approval, which must be suitable for the type of cable being
used and also meet the requirements of the current flameproof
installation standards (see section 7.1).
Blanking Plugs
When only one cable entry is used the other entries must be
closed with suitably rated and certified blanking plugs as per
type of approval.
Any unused cable entries must be closed with suitably rated
and certified blanking plugs.

Ingress Protection
If a high IP (Ingress Protection) rating is required, then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs. A minimum ingress protection rating of IP6X
must be maintained for installations in explosive dust
atmospheres.
For combustible dust applications, the cable entry device and
blanking elements shall be in type of explosion protection and
shall have an IP 6X rating
For use in Class I Division II locations, in order to maintain the
db type protection, flameproof conduit seals and/or cable
glands must be used.
Adapters
The STEx Beacon Range can be supplied with the following
types of adapters:
M20 to ½” NPT
M20 to ¾” NPT
M20 to M25
It is important to note that stopping plugs cannot be fitted onto
adapters, only directly onto the M20 entries.
Any other adapters used must be suitably rated as per the
applicable standards.
If the installation is made using conduit, openings must have a
sealing fitting connected as close as practical to the wall of the
enclosure, but in no case more than the size of the conduit or
50mm, whichever is the lesser.
8) Flash Pattern Settings
6.1 Flash Rate Setting
The STExB2 beacons can produce different flash patterns as
shown in Table 2. The flash patterns are selected by operation
of the flash setting DIP switch on the PCBA (See Fig 6).

9) End of Line Monitoring (DC Units)
All DC units have a blocking diode fitted in their supply input
lines. An end of line monitoring diode or an end of line
monitoring resistor can be connected across the +ve and –ve
terminals in the flameproof chamber. If an end of line resistor
is used it must have a minimum resistance value of 3k3 ohms
and a minimum wattage of 0.5W or a minimum resistance
value of 500 ohms and a minimum wattage of 2W.
10) Interchangeable & Spare Parts
The beacon lens is interchangeable, contact European Safety
Systems Ltd for a replacement lens available in various
colours.
The guard is an integral part of the protection and must be
reassembled exactly the same way as it was disassembled.
To change the lens, unscrew the M5 socket head screws and
remove the M5 screws, M5 spring & flat washers.
Figure 7: Removal of Lens.
Warning –Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
Warning –high-intensity light source.
Avoid looking directly at the light source for
extended periods of time.

11) Maintenance, Overhaul and Repair
Maintenance, repair and overhaul of the equipment should
only be carried out by suitably qualified personnel in
accordance with the current relevant standards:
EN60079-19/IEC60079-19 Explosive atmospheres –
Equipment repair, overhaul and reclamation
EN 60079-17/IEC60079-17 Explosive atmospheres –
Electrical installations inspection and maintenance
Units must not be opened while an explosive atmosphere is
present.
If opening the unit during maintenance operations a clean
environment must be maintained and any dust layer removed
