3. Thermoelectric installation
IMPORTANT WARNING: Solder joints of the wires to the
thermoelectric module are extremely fragile. Bending the wires at their
root will break the solder joint, with no possible repair. Swiftech will
not honor the warranty for broken wires.
Connection to a dedicated auxiliary power supply
(recommended):
The TEC module is provided with “bare wires” to facilitate installation
with screw type terminals. We recommend the “Meanwell S320-12”
power supply, available on our website in the Thermoelectric
accessories section.
Connect red wire from TEC module to the +V terminal, and black wire
to the –V terminal as shown in figure 3 below:
Minimum requirements for a dedicated power supply: 25A @ +12 V.
If adjustable voltage is available: setting the voltage higher than +12V
is not recommended. Lower voltage, can be safely used, down to 9
volts.
Connection to an ATX computer power supply:
Important Warning: to connect the MCX4000-T cooler to an ATX
computer power supply, you must carefully consider the existing
requirements of other devices connected on the +12V line. Connecting
to an underpowered unit will definitely damage the power supply.
Minimum requirements for an ATX computer power supply: 37A at
+12V in a typical computer setup.
If you are nevertheless going to connect the MCX4000-T to a
computer power supply, you need to cut the wiring to one of the power
supply Molex connectors, and use a different connector between power
supply, and thermoelectric. This is because Molex connectors are not
rated for 25 Amps current, and may overheat.
Use a euro-style wire connector as shown in fig 4 below, or similar
device with a current rating of at least 25 amps. Connect red wire from
TEC module to +12V of P/S (Yellow wire), and black wire to black wire:
If you need wiring extensions: use 16 gage stranded wire. Connect
the extension to the existing wires with terminal splices, or solder the
butts, and insulate with shrink tubing.

FINAL TIPS:
FAN RECOMMENDATIONS: THE MINIMUM RECOMMENDED AIRFLOW RATING IS 68CFM. FOR OPTIMUM PERFORMANCE, 80 CFM
IS PREFERRED.
AIR COOLED THERMOELECTRIC DEVICES REJECT A SIGNIFICANT AMOUNT OF HEAT INSIDE YOUR CASE. YOUR PROJECT
DESIGN SHOULD INCLUDE CAREFUL CONSIDERATION TO CASE VENTILATION.
