2 Speed Swamp Cooler Motor Wiring Diagram Enhandmade Connect the switch: if your swamp cooler has a 2 speed switch, connect the high speed wire from the motor to the terminal marked “hi” on the switch, and the low speed wire to the terminal marked “lo.”. ensure that the switch is properly wired and tightened. secure the ground wire: attach the ground wire from the motor to the grounding. This guide will walk you through the process of wiring a 2 speed cooler motor, providing you with a complete wiring diagram and helpful tips along the way. the first step in wiring a 2 speed cooler motor is to gather all the necessary tools and materials. you will need a wire stripper, wire nuts, electrical tape, and a wiring diagram specific.
2 Speed Cooler Motor Wiring Diagram Connect the high speed wire: take the high speed wire and connect it to the corresponding terminal on the motor. this wire is usually labeled “h” or “high.”. use a screwdriver to secure the wire in place. connect the low speed wire: take the low speed wire and connect it to the corresponding terminal on the motor. Make sure all connections are secure and tight. attach terminal board cover plate making sure all wires are inside and not between cover and motor. see fig. 2. note make sure incoming line voltage agrees with motor nameplate voltage. 624 south b street, tustin, ca 92780 • 800.636.8866 • 714.505.1166 • f. 714.505.1160 advantageman . Step 2: connecting the supply line. determine the location of the black power supply line. then attach it to the switch’s center terminal. then, using a red wire, connect the switch to the motor’s low speed contact. the high speed connection of the motor should then be connected to the switch. The wiring diagram will indicate which wire should be connected to the corresponding terminal. two speed motors: two speed motors offer more flexibility for controlling the speed of the evaporative cooler. these motors typically have three wires, labeled “high,” “medium,” and “low.”. the “high” wire is used for the highest speed.

Typically the color coded connections should be made as explained in the following steps. connect the green wire to the ground in the 120 volt circuit. connect the red wire to the low fan speed in the control circuit. connect the black wire to high fan speed in the 120 volt circuit. connect the white wire to neutral in the 120 volt circuit. Identify the black power supply wire and connect it to the center terminal on the switch. next, use a red wire to connect the switch to the low speed terminal of the motor. then, use a black wire to connect the switch to the high speed terminal of the motor. you can now turn on the power to your motor and test that the switch works properly.
