Guidelines
Electrical wiring must comply with all applicable codes. Operating
conditions and site equipment that may be of concern should be
discussed with local operating personnel to determine if any special
needs should be considered.
Ground the shield at the main control panel. Connect the shield wire in
the sensor terminal block labelled shield. Tape all exposed shield wire at
the sensor to insulate it from the enclosure.
Electrical Power: 24 VDC/VAC nominal, 0.35 amp maximum. Either AC
or DC may be connected to the terminal block.
Wire: Signal wiring should be done with #20-24 AWG shielded twisted
pair cable Belden 9841 or similar. Network units should have no more
than 2,000 ft (600 m) of #22 AWG wire. Smaller gauge sizes are limited
by the same resistance limit.
Power wiring should be sized by local codes, but never less than #20
AWG, 120 VAC wiring should be #14 or #12 AWG.
