Installation
The transformer is located in the control panel. The circuit breaker is located on
the left side of the transformer and can be reset by pressing in on the black reset
button.
Controls using 24 VAC
Before installing any connecting wiring, refer to
Unit Dimensions
for the
electrical access locations provided on the unit and
Table 2
for AC conductor
sizing guidelines, and;
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.
Note:
Resistance in excess of 3 ohms per conductor may cause 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
Figure 11
.
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
for the
electrical access locations provided on the unit.
1.
Table 3
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.
