8.5 TIIS
CAUTION
The model AXF
ٗٗٗC magnetic flowmeter with
optional code JF3, which has obtained
certification according to technical criteria for
explosion-protected construction of electric
machinery and equipment (Standards
Notification No. 556 from the Japanese Ministry
of Labor) conforming to IEC standards, is
designed for hazardous areas where
inflammable gases or vapors may be present.
(This allows installation in Division 1 and 2
areas)
To preserve the safety of flameproof 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 PRECAUTIONS FOR TIIS
FLAMEPROOF EQUIPMENT” at the end of this
manual.
