Intrinsic Safety
When connecting equipment in hazardous areas, certain requirements must be fulfilled to
comply to the equipment safety certification and cable installation. There are requirements
both for the equipment in the hazardous area on deck and for the associated apparatus in
the nonhazardous area.
Safety Certifications
The MAS 2600 Level Transmitter is intrinsically safe and meets the requirements of all the
major classification societies. The MAS 2600 has the following safety Ex-certifications:
• ATEX: II 2(1) G Ex ia [ia Ga] IIC T4 Gb
• IECEx: Ex ia [ia Ga] IIC T4 Gb
The MAS 2600 is certified by UL international Demko A/S (certificate DEMKO 11 ATEX
146506X and IECEx Certificate of Conformity no IECEx ULD 10.0013X).
Intrinsic Safety Principle
Intrinsic safety is based on the principle of restricting electrical energy available in hazard-
ous-area circuits, so that any sparks or hot surfaces, that may occur as a result of electrical
faults in components, have too low energy content to cause ignition.
An intrinsic safe environment allows the crew or the service personnel to safely maintain
the equipment while the ship is in operation.
Precautions are necessary to maintain in safe environment. Precautions related to installa-
tion and special considerations for safe use are to be found on page 31.
