General
Standard cases have 2 electrical circuits: the fan circuit and the lighting circuit ( See Figure 40 ). Always refer to the wiring diagram shipped
with the case.
The case light switch is located on the right side of the interior ceiling ( See Figure 41 ).
The electrical enclosure is located behind the lower trim on the right side of the case ( See
Figure 42 ). The electrical raceway allows for simple case-to-case wiring ( See Figure 43 ).
power can be supplied to the case through the access hole under the electrical enclosure
( See Figure 44 ). The enclosure includes the power connection and power supplies for the
LED light bars. Terminal blocks are provided for supplying power for fans and lights. A ground
connection can also be made inside the electrical enclosure.
Optional top electrical will be located in a junction box on top of the case.
The factory-installed temperature probe (discharge air) is located in the false ceiling.
Temperature probe wires are white (common) and green (supply).
