1 The installation must meet the requirements of the National Electric Code,
Canadian Electrical Code Part I, Article 504, NFPA 70, and ANSI/ISA 12.06.01.
2
Individually shielded cables needed to ensure separation of sensor and
transducer circuits.
3
The voltage (Vmax or Ui), current (Imax or Ii), and power (Pi) must be equal to or
greater than the voltage (Voc, Uo, or Vt), current (Isc, Io, or It), and power (Po or
Pt) levels, which can be delivered by the associated apparatus. In addition, the
maximum unprotected capacitance (Ci) and inductance (Li) of the intrinsically
safe apparatus, including interconnecting wiring, must be less than the
capacitance (Ca) and inductance (La) which can be safely connected to the
associated apparatus.
5
Land shield drain and foil to conductive strain relief.
