°
C (T4)
• Supply voltage: 42 V dc max.
• Output Signal: 4 to 20 mA
• Ambient Temperature: –40 to 80
°
C
Note 2. Wiring
• All wiring shall comply with the Australian
Standard.
Note 3. Operation
• Keep the “CAUTION” label attached to the
transmitter.
CAUTION: AMBIENT TEMPERATURE
ABOVE 75 DEG C SELECT SUITABLE
CABLE.
DISCONNECT POWER AND WAIT 1
MINUTE BEFORE REMAKING COVER
• 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 is prohibited and
will void Standards Association of Australia
Flameproof Certification.

Note 3. Installation
• All wiring shall comply with local installation
requirements. (Refer to the installation diagram)
Note 4. Maintenance and Repair
• The instrument modification or parts replacement
by other than authorized representative of
Yokogawa Electric Corporation is prohibited and
will void KEMA Intrinsically safe Certification.
Note 5. Special Conditions for Safe Use
• 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 1 G apparatus
is required, it must be installed such, that, even in
the event of rare incidents, ignition sources due to
impact and friction sparks are excluded.
