E2S BExCBG05-05D Instruction Manual

1) Introduction
The BExCBG05-05D is a flameproof combined beacon /
beacon which is certified to meet the requirements of the
ATEX directive 94/9/EC and the IECEx scheme. Each
beacon section produces a synchronised visual warning
signal and has a flash energy of 5 joules. The unit can be
used in hazardous areas where potentially flammable gas
and dust atmospheres may be present. The unit can be used
in Zone 1 and Zone 2 areas with gases in groups IIA and IIB
and with Temperature Classifications of T1, T2, T3, T4 and
T5 and can also be used in Zone 21 and Zone 22 areas for
combustible dusts and have an IP rating of IP 67 and a
surface temperature rating of T115ºC (T100ºC at +55ºC).

Installation Requirements
The unit must be installed in accordance with the latest
issues of the relevant parts of the EN60079 specifications or
the equivalent IEC specifications – Selection, Installation and
maintenance of electrical apparatus for use in potentially
explosive atmospheres (other than mining applications or
explosive processing and manufacture):-
EN60079-14:2008
IEC60079-14:2007 (Ed4)
EN60079-10:2003
IEC60079-10:2008 (Ed1)
The installation of the unit 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.
