ATTENTION
European Hazardous Location Approval
ASSOCIATED APPARATUS Certification
(The following applies when the product bears the Ex or EEx Marking)
This equipment is intended for use in potentially explosive atmospheres as defined by European Union
Directive 94/9/EC.
The LCIE (Laboratoire Central des Industries Electriques) certifies that this equipment has been found to
comply with the Essential Health and Safety Requirements relating to the design and construction of
apparatus for use in safe areas with Intrinsically Safe Circuits intended for use in potentially explosive
atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has been assured by compliance with EN
60079-0 and EN 60079-11.
WARNING
•Equipment connected to the non-intrinsically safe side must not use or generate voltages greater than
250V rms.
•Provides intrinsically safe circuits with entity parameters of Voc = 38.2V, Isc = 40mA, Ca = 10nF, and La =
20mH when connected to thermocouples or other devices that do not contain energy storing or
generating components.
•Each intrinsically safe channel must use a shielded grounded cable. Cable inductance must be below the
Ca and La parameters of each intrinsically safe channel.
