Notes

Install per National Code an local codes, as applicable. Installation should be

in accordance with ANSI/ISA RP12.6

Associated apparatus (barrier) must be entity - approved by FMRC, used in

an approved configuration and installed in accordance with barrier

manufacturer's instructions. Transmitter Vmax must be greater or equal to

barrier Vt or Voc.

Transmitter Vmax must be greater or equal to barrier It or Isc. Transmitter

Imax must be greater or equal to barrier It or Ioc. Transmitter Pmax must be

greater or equal to barrier Po.

Total cable capacitance plus Ci of transmitter shall not exceed Ca of barrier.

Total cable inductance plus Li of transmitter shall not exceed La of barrier.

Vmax >= Voc or Vt

Imax >= Isc or It

Pi >= Po

Ci + Ccable <= Ca

Li + Lcable <= La
