TWO POWER SUPPLIES OPERATION:
Make sure the power supplies are NOT energized while making electrical connections to the controller.
The output voltage of the TE Device Power Supply should not exceed the maximum desired input voltage of
the thermoelectric device, or the rated input voltage of the cooling assembly.
a) Connect the DC voltage power supply (for powering the controller electronics) to the controller (≥12 V and ≤36 V,
150 mA minimum):
i) Connect wire between Positive (+) terminal of the power supply and JP2-9.
ii) Connect wire between Negative (-) terminal of the power supply and JP2-7.
b) Connect the DC voltage power supply (for powering the TE device) to the controller (>0 V but ≤36 V):
i) Connect wire between Positive (+) terminal of the power supply and JP7-4.
ii) 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.
