2.7 SEM310X VERSION - FOR USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES
2.7.1 ATEX CERTIFICATE
The SEM310X, has been issued with a EC-type examination certificate, confirming compliance with
the European ATEX directive 94/9/EC for :-
Intrinsic safety
II 1 G EEx ia IIC T4…T6.
The equipment bears the Community Mark and subject to local codes of practice, may be installed in
any of the European Economic Area (EEA) member countries. The SEM310X housing is coloured
light blue to identify the equipment as suitable for Hazardous area use. The equipment must be
installed and maintained in accordance with local requirements for electrical equipment for use in
potentially explosive atmospheres, eg EN60079-14 & EN60079-17. This instruction sheet describes
installation which conforms with BS EN60079-14 & BS EN60079-17 Electrical Installation in
Hazardous Areas. When designing systems outside the UK, the local Code of Practice should be
consulted.
