2. HANDLING CAUTIONS
• WARNING:
WHEN AMBIENT TEMPERATURE ≥ 65°C,
USE THE HEAT-RESISTING CABLES ≥ 90°C.
QUAND LA TEMPÉRATURE AMBIANTE ≥
65°C, UTILISEZ DES CÂBLES RÉSISTANTES Á
LA CHALEUR ≥ 90°C.
• Take care not to generate mechanical sparking
when accessing to the instrument and peripheral
devices in a hazardous location.
Note 4. Maintenance and Repair
• The instrument modification or parts replacement
by other than authorized representative of
Yokogawa Electric Corporation and Yokogawa
Corporation of America is prohibited and will void
Canadian Standards Explosionproof Certification.
