Installation notes.
The Transmitter must be installed in a suitable enclosure to meet installation codes
stipulated in The National Electrical Code (ANSI-NFPA 70).
When installed in Class II locations the Transmitter shall be installed in an enclosure
with a specified ingress protections of IP6X according to IEC60529 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
MAX
which the device can receive and remain intrinsically safe, must be equal to or
