Each pair of I.S. wires must be protected by a shield that is grounded at the I.S. Ground. The shield must be extend as close
to the terminals as possible installation shall be in accordance with the National
Electrical Code ANSI/NFPA 70 and ANSI/ISA RP 12.06.01.
The total series inductance and shunt capacitance of shield wiring shall be restricted to the following maximum values
maximum capacitance of each inductive sensor 30nF
maximum inductance of each inductive sensor 100µH
