Note 2. Electrical Data
• Supply voltage: 32 V dc max.
Output current: 15 mA dc
Note 3. Installation
• All wiring shall comply with local installation
requirements.
• The cable entry devices shall be of a certied
ameproof type, suitable for the conditions of
use.
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 the instrument and
peripheral devices in hazardous location.
Note 5. Special Conditions for Safe Use
WARNING
• Electrostatic charge may cause an exlosion
hazard. Avoid any actions that cause the
gerenation of eletrostatic 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 ow of
dust is avoided.
• The instrument modication or parts
replacement by other than an authorized
Representative of Yokogawa Electric
Corporation is prohibited and will void the
certication.
• To satisfy IP66 or IP67, apply waterproof
glands to the electrical connection port.
