•Enclosure: IP66 and IP67
Note 2. Electrical Data
•In type of explosion protection intrinsic safety EEx ia IIC only for connection to a certified intrinsically safe circuit with following maximum values:
Ui = 30 V Ii = 200 mA Pi = 0.9 W
Effective internal capacitance; Ci = 10 nF Effective internal inductance; Li = 0 mH
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 DEKRA(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.
