3) Type Approval Standards
The beacons have an EC Type examination certificate and
IECex Certificate of Conformity issued by Dekra and have
been approved to the following standards:
EN60079-0:2012 + A11 and EN IEC 60079-0 :2018 /
IEC60079-0:2017 (Ed 7): Explosive Atmospheres -
Equipment. General requirements
EN60079-1:2014 / IEC60079-1:2014 (Ed 7): Explosive
Atmospheres - Equipment protection by flameproof
enclosures "d"
EN60079-31:2014 / IEC60079-31:2013 (Ed2):
Explosive Atmospheres - Equipment dust ignition protection
by enclosure "t"
4)
Installation Requirements
The beacons 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.
5) Special Conditions of Use
Repair of the flamepath / flameproof joints is not permitted.
The enclosure is non-conducting and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions (such as high-pressure steam). 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.
Additionally, cleaning of the equipment should be done only
.
with a damp cloth
6) 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.
SAFETY WARNING: The BExBG10D-P and BExBG15D-P
10 and 15 joule beacons must be mounted with their
flashdome in a position between upright and 90º as shown.

The beacons should be securely bolted to a suitable surface
using at least two of the 7mm diameter boltholes in the
stainless steel U shaped mounting bracket (see figure 1). The
angle can then be adjusted as required but the mounting
restrictions must be observed (see above). This can be
achieved by loosening the two large bracket screws in the
side of the unit, which allow adjustment in steps of 18°. On
completion of the installation the two large bracket
adjustment screws on the side of the unit must be fully
tightened to ensure that the unit cannot move in service.

7) Access to the Flameproof Enclosure
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.
To access the Ex d chamber, remove the four M6 hexagon
socket head screws and withdraw the flameproof cover taking
extreme care not to damage the flameproof joints in the
process. M6 cover screws are Class A4-80 stainless steel
and only screws of this category can be used for the
enclosure.
(Appropriate cable glands
to be customer supplied)
Fig. 2 Accessing the Explosion proof Enclosure.
On completion of the cable wiring installation the flameproof
joints should be inspected to ensure that they are clean and
that they have not been damaged during installation.
Check that the earth bonding wire between the two casting
sections is secure and the 'O' ring seal is in place. When
replacing the flameproof cover casting ensure that it is square
with the flameproof chamber casting before inserting.
Carefully push the cover in place allowing time for the air to
be expelled. Only after the cover is fully in place should the
four M6 Stainless Steel A4-80 cover bolts and their spring
washer be inserted and tightened down. If the cover jams
while it is being inserted, carefully remove it and try again.
Never use the cover bolts to force the cover into position.
