Installation notes
For installation in Class I the Transmitter must be installed in a suitable enclosure to meet installation
codes stipulated in The National Electrical Code (ANSI-NFPA 70).
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
Pi(Pmax), which the device can receive and remain intrinsically safe, must be equal to or greater than
the voltage (Uo or V
the barrier. 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
interconnecting wiring must be less than the inductance (L
barrier. The entity parameters Uo, V
the barrier manufacturer.
