E2S GNExB2LD2 Instruction Manual

1) Introduction
The GNExB2LD2 are flameproof beacons which are 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 GNExB2LD2 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, T4, T5 & T6. The
unit can be used in Zone 21 and Zone 22 with dusts in
groups IIIA, IIIB and IIIC and have a surface temperature
rating of T85°C.
2) Marking
All units have a rating label, which carries the following
important information:-

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:
Classification of areas. Explosive gas atmospheres
EN60079-10-2 / IEC60079-10-2:
