14.5 TIIS

The model AXRC magnetic flowmeter
with optional code JF3, which has obtained
certification according to technical criteria
for explosion proof 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 Zone 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.
