Note 3. Installation
• In any safety barreir used output current
must be limited by a resistor ‘R’ such that
Io=Uo/R or Isc=Voc/R.
• The safety barrier must be CSA certified.
• Input voltage of the safety barrier must be
less than 250 Vrms/Vdc.
• Installation should be in accordance with
Canadian Electrical Code Part I and Local
Electrical Code.
• Dust-tight conduit seal must be used when
installed in Class II and III environments.
•
The instrument modification or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation and Yokogawa Corporation
of America is prohibited and will void
Canadian Standards Intrinsically safe and
nonincendive Certification.
