Approvals/Certifications
Each of the meter selections (SM/DM/ME) itself carries no approvals or certifications for use in hazardous
areas (or for RFI, etc). However, when it is properly installed in the flameproof/explosion-proof housing,
or when installed as intrinsically safe, the meter is covered by the approvals and certifications of the
housing (or as intrinsically safe) and of the installation practices used therewith. When installed as
intrinsically safe, external wiring shall be in accordance with ordinary location requirements; that is, NEC
or CEC or local codes.
For information regarding integral installation in Honeywell Smart Transmitters refer to the following
publications.
