1.3.1 ONE POWER SUPPLY OPERATION:
Make sure the power supply is NOT energized while making electrical connections to the controller.
The output voltage of the TE Power Supply should not exceed the maximum desired input voltage of the
thermoelectric device, or the rated input voltage of the cooling assembly.
If voltage is not between 12 V to 36 V then a two power supply configuration is necessary.
Connect the DC voltage power supply (output voltage: ≥12 V but ≤36 V) to the controller as follows:
a) Connect wire between Positive (+) terminal of the power supply and JP7-4.
b) Connect wire between Negative (-) terminal of the power supply and JP7-3.
c) See Section 1.4 for further information on connecting the TE device.
