The model AXFCmagneticowmeterand
AXFA14C remote converter with optional code
JF3,whichhaveobtainedcerticationaccordingto
technical criteria for explosion-protected construction
of electric machinery and equipment (Standards
NoticationNo.556fromtheJapaneseMinistryof
Labor) conforming to IEC standards, are designed for
hazardousareaswhereinammablegasesorvapors
may be present. (This allows installation in Division 1
and 2 areas)
Topreservethesafetyofameproofequipment
requires great care during mounting, wiring, and
piping. Safety requirements also place restrictions on
maintenance and repair activities. Users absolutely
mustread“INSTALLATIONANDOPERATING
