Type Approval Standards
3)
The beacon carries an EC Type Examination Certificate of
Conformity, and have been certified to comply with the fol-
lowing standards:
EN IEC 60079-0 :2018 / IEC60079-0:2017 (Ed 7): Explosive
Atmospheres - Equipment. General requirements
EN60079-1:2014 / IEC60079-1:2014 (Ed 7): Explosive At-
mospheres - Equipment protection by flameproof enclo-
sures "d"
EN 60079-7:2015 +A1: 2018/IEC 60079-7:2017 (Ed 5.1):
Explosive Atmospheres - Equipment protection by in-
creased safety "e"
EN 60079-31:2014 / IEC60079-31:2013 (Ed 2):
Explosive Atmospheres - Equipment dust ignition protection
by enclosure "t"
4) Installation Requirements
The beacon must only be installed by suitably qualified per-
sonnel in accordance with the latest issues of the relevant
standards:
EN60079-14 / IEC60079-14: Explosive atmospheres - Elec-
trical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive gas atmospheres
EN60079-10-2 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive dust atmospheres
The installation of the beacon must also be in accordance
with any local codes that may apply and should only be car-
ried out by a competent electrical engineer who has the nec-
essary training.
5) Special Conditions of Use
Repair of the flamepath / flameproof joints is not permitted.
The enclosure is non-conducting and may generate an igni-
tion-capable level of electrostatic charges under certain ex-
treme 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 beacon 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.
The BEx beacon should be secured to any flat surface using
at least two of the three 7mm fixing holes on the stainless
steel U shaped mounting bracket. See Figure 1. The required
angle can be achieved by loosening the two large bracket
screws in the side of the unit, which allow adjustment of the
beacon in steps of 18°. On completion of the installation then
two large bracket adjustment screws on the side of the unit
must be fully tightened to ensure that the unit cannot move in
service.

Warning – High voltage may be present,
risk of electric shock. DO NOT open
when energised, disconnect power be-
fore opening.
Warning – Hot surfaces. External sur-
faces and internal components may be
hot after operation, take care when han-
dling the equipment.
To access the Ex d chamber, remove the four M6 hexagon
socket head screws and withdraw the flameproof cover tak-
ing 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 enclo-
sure.
(Appropriate cable glands
to be customer supplied)

On completion of the 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 castings
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 Stain-
less Steel A4-80 cover bolts and their spring washer be in-
serted 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.
