Dc Conductors - Trane YSC037E Installation & Operation Manual

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 38.
