Approvals/Certifications
Each of the meter selections (ME/EU) 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.
