Install per Canadian ElectricalCode (Part 1) and local codes, as applicable

Associated apparatus (barrier) must be entity -certified by CSA, used in an

certified configuration and installed in accordance with barrier manufacturer's

instructions. Transmitter Vmax must be greater or equal to barrier Vt or Voc,

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

Transmitter Pmax must be greater or equal to barrier Pmax.

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

Pmax >= Pmax (barrier)

Ci + Ccable <= Ca

Li + Lcable <= La
