Note 4. Operation
• Keep the “WARNING” label attached to the
transmitter.
WARNING: AFTER DE-ENERGIZING,
DELAY 5 MINUTES BEFORE OPENING.
WHEN THE AMBIENT TEMP.≥65°C, USE
HEAT-RESISTING CABLE AND CABLE
GLAND ≥90°C.
• Take care not to generate mechanical
sparking when accessing to the instrument
and peripheral devices in a hazardous
location.
Note 5. Specific Conditions of Use
WARNING
• Electrostatic charge may cause an explosion
hazard. Avoid any actions that cause the
generation of electrostatic charge, such as
rubbing with a dry cloth on coating face of
the product.
• In the case where the enclosure of the
Pressure Transmitter is made of aluminium,
if it is mounted in an area where the use of
category 2D apparatus is required, it shall
be installed in such a way that the risk from
electrostatic discharges and propagating
brush discharges caused by rapid flow of
dust is avoided.
• The instrument modification or parts
replacement by other than an authorized
Representative of Yokogawa Electric
Corporation is prohibited and will void the
certification.
• The fasteners used to fasten the transmitter
enclosure onto the sensor capsule is special
fastener, and the property class of it is
A2-50(A4-50) or more.
• Maximum Surface Temperature for dust-proof:
T85°C (Tamb.: –30* to 75°C, Tp.: –30* to 85°C)
* –15°C when /HE is specified.
