Connect the L1 phase to one terminal of the control transformer, and link the other transformer terminal to the neutral line. This guide breaks down the components, the wiring sequence, and the safety protocols required for a successful implementation.

Finally, the control transformer steps down the voltage to provide safe 24V AC for the start and stop buttons and the contactor coil. Understanding the Core Components Before connecting any wires, you must identify the key devices in the control circuit.
The main contactor is the heavy-duty switch that handles the high current of the three phase lines to the motor. This path ensures that when the contactor pulls in, power is delivered directly to the motor.

The first step is to lock out the main power supply using a lockout/tagout (LOTO) procedure to prevent accidental energization. You will connect the incoming lines (L1, L2, L3) to the top terminals of the contactor, typically marked L1, L2, and L3.
