The entity concept
The Transmitter must be installed according to National Electrical Code
(ANSI-NFPA 70).
When installed in Class II locations the Transmitter shall be installed in an enclosure with a specified
ingress protection of IP6X according to IEC 60529 and dust-tight conduit seals must be used.
Equipment that is FM-approved for intrinsic safety may be connected to barriers based on the ENTITY
CONCEPT. This concept permits interconnection of approved transmitters, meters and other devices in
combinations which have not been specifically examined by FM, provided that the agency's criteria are
met. The combination is then intrinsically safe, if the entity concept is acceptable to the authority having
jurisdiction over the installation.
The entity concept criteria are as follows:
The intrinsically safe devices, other than barriers, must not be a source of power.
The maximum voltage Ui(V
receive and remain intrinsically safe, must be equal to or greater than the voltage (Uo or V
current (Io or I
The sum of the maximum unprotected capacitance (C
interconnecting wiring must be less than the capacitance (C
barrier.
The sum of the maximum unprotected inductance (L
wiring must be less than the inductance (L
