LS Direct Online Starter Wiring 1 Phase

A direct online starter is a type of motor starter that is used to start a three-phase AC motor directly from the line voltage. This type of starter is simple and inexpensive, but it can be hard on the motor, especially if the motor is not properly sized for the application. A direct online starter consists of a contactor, a thermal overload relay, and a disconnect switch. The contactor is a switch that is used to connect the motor to the line voltage. The thermal overload relay is a device that protects the motor from overheating. The disconnect switch is a safety device that allows you to disconnect the motor from the line voltage. To wire a direct online starter for a one-phase motor, you will need the following materials: * A direct online starter * A three-pole contactor * A thermal overload relay * A disconnect switch * A set of wire nuts * A set of lugs * A piece of EMT conduit * A set of conduit fittings

Step 1: Install the conduit.

The first step is to install the conduit. The conduit will protect the wires from damage and will help to keep the installation neat and organized. To install the conduit, you will need to cut a piece of EMT conduit to the desired length. Then, you will need to install a conduit fitting at each end of the conduit. Finally, you will need to install the conduit in the wall or ceiling.

Step 2: Connect the wires to the contactor.

The next step is to connect the wires to the contactor. The contactor has three terminals: L1, L2, and L3. These terminals correspond to the three phases of the line voltage. To connect the wires to the contactor, you will need to use a set of wire nuts. First, strip the ends of the wires. Then, twist the wires together and put a wire nut on the end of the twist. Finally, connect the wire nut to the corresponding terminal on the contactor.

Step 3: Connect the wires to the thermal overload relay.

The next step is to connect the wires to the thermal overload relay. The thermal overload relay has two terminals: T1 and T2. These terminals correspond to the two motor leads. To connect the wires to the thermal overload relay, you will need to use a set of lugs. First, strip the ends of the wires. Then, slide the lugs onto the wires. Finally, tighten the lugs onto the terminals on the thermal overload relay.

Step 4: Connect the wires to the disconnect switch.

The next step is to connect the wires to the disconnect switch. The disconnect switch has three terminals: L1, L2, and L3. These terminals correspond to the three phases of the line voltage. To connect the wires to the disconnect switch, you will need to use a set of wire nuts. First, strip the ends of the wires. Then, twist the wires together and put a wire nut on the end of the twist. Finally, connect the wire nut to the corresponding terminal on the disconnect switch.

Step 5: Test the starter.

Once you have connected all of the wires, you can test the starter. To test the starter, you will need to turn on the power to the starter. Then, you will need to press the start button on the starter. The motor should start running. If the motor does not start running, you will need to troubleshoot the problem. Some common problems include: * The wires are not connected correctly. * The thermal overload relay is tripped. * The disconnect switch is turned off. Once you have identified and fixed the problem, you can try starting the motor again.
