•

lists the conductor sizing guidelines that

must be followed when interconnecting the DC binary
output devices and the system components utilizing a
DC analog input/output signal to the unit.

Note:

Resistance in excess of 2.5 ohms per conductor can
cause deviations in the accuracy of the controls.

Note:

Ensure that the wiring between controls and the
unit’s termination point does not exceed two and a
half (2.5) ohms/conductor for the length of the run.

•

Do not run the electrical wires transporting DC signals
in or around conduit housing high voltage wires.

•

Route low voltage wiring per illustrations on page
