2. NOTES ON HANDLING
Note 2. Entity Parameters (Electrical/Non-
incendive field wiring parameters)
• [Supply Circuit]
Vmax = 30 V, Imax = 165 mA, Pmax = 0.9 W
Ci = 18 nF, Li = 730 µH
• [Associated apparatus]
Voc 30 V, Isc 165 mA, Pmax 0.9 W
• [Sensor Circuit]
Voc = 9 V, Isc = 40 mA, Po = 90 mW,
Ca = 1 µF, La = 10 mH
Note 3. Installation
• All wiring shall comply with Canadian Electrical
Code Part I and Local Electrical Codes.
• For the sensor circuitry, the above parameters for
sensor circuit must be taken into account.
• Dust-tight conduit seal must be used when installed in
class II and III environments.
• In any used safety barrier, output current must be
limited by a resistor 'R' such that Isc=Voc/R.
• The safety barrier must be CSA certified, and the
input voltage of the barrier must be less than
250Vrms/Vdc.
• For non-incendive type, general purpose equipment
must be CSA certified and the equipment which have
non-incendive field wiring parameters.
• The instrument modification or parts replacement by
other than authorized representative of Yokogawa
Electric Corporation is prohibited and will void
Canadian Standards Intrinsically safe and
nonincendive Certification.
