European Safety Systems BE BG05D Serie Manual De Instrucciones

1) Introduction
The BExBG05D is a flameproof beacon which is certified to
meet the requirements of the ATEX directive 94/9/EC and the
IECEx scheme. The beacon produces synchronised visual
warning signals and can be used in hazardous areas where
potentially flammable gas and dust atmospheres may be
present. The BExBG05D has a flash energy level of 5 joules
and can be used in Zone 1 and Zone 2 areas with gases in
groups IIA, IIB and IIC and Temperature Classifications of T1,
T2, T3 and T4. The unit can also be used in a temperature
classification T5, if the upper ambient temperature is
restricted to +55ºC and T6 if the upper ambient temperature
is restricted to +40ºC. The unit can be used in Zone 21 and
Zone 22 areas for combustible dusts and has an IP rating of
IP 67 and a surface temperature rating of T115ºC or T100ºC
if the upper ambient temperature is restricted to +55ºC and
T85ºC if the upper ambient temperature is restricted to
+40ºC.

Installation Requirements
The beacons must be installed in accordance with the latest
issues of the relevant parts of the EN60079 standards or the
equivalent IEC standards – 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 Electrical Installations in Hazardous
IEC60079-14:2007 (Ed4) Areas (other than mines)
EN60079-10:2003 Classification of Hazardous Areas
IEC60079-10:2008 (Ed1)
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.
