1. Use copper conductors unless otherwise specified.
2. Ensure that the AC control wiring between the controls
and the unit's termination point does not exceed three
(3) ohms/conductor for the length of the run.
NOTICE:
Component Failure!
Resistance in excess of 3 ohms per conductor could
result in component failure due to insufficient AC
voltage supply.
3. Be sure to check all loads and conductors for grounds,
shorts, and mis-wiring.
4. Do not run the AC low voltage wiring in the same
conduit with the high voltage power wiring.
5. Route low voltage wiring per illustrations on
p.
21.

Controls Using DC Analog Input/Outputs
(Standard Low Voltage Multiconductor Wire)
Before installing any connecting wiring between the unit
and components utilizing a DC analog input\output signal,
refer to
"Unit Dimensions, " p. 11
locations provided on the unit.
1.
Table 5, p. 21
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.
2. 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.
3. Do not run the electrical wires transporting DC signals
in or around conduit housing high voltage wires.
