Guide to connecting a 3-phase electric motor

Step 1: Open the motor terminal box

• Prepare a Phillips screwdriver.
• Turn counterclockwise to remove the 4 fixing screws at the four corners of the terminal box cover located on the motor body.
• Lift off the terminal box cover to access the terminal posts inside.

Step 2: Identify terminal posts and connect power wires

• Prepare wires: Ensure you have prepared 3 wires for the 3-phase power supply (380V).
• Locate terminals: Observe the terminal board inside the terminal box. You will see terminal posts (usually 6 posts, where the 3 upper posts are pre-connected with copper bars in star or delta configuration depending on the setup). You will connect power to the 3 posts in the bottom row.
• Wiring procedure: Sequentially attach and tighten the 3 power wires to the terminal posts marked accordingly as follows:
  • Connect the first power wire to terminal U1.
  • Connect the second power wire to terminal V1.
  • Connect the third power wire to terminal W1.
• Note: Ensure that the connections are tight and make good contact to avoid arcing or phase loss during operation.

Step 3: Test run the motor

• After securely connecting the 3 power phases to the exact U1, V1, W1 terminals, clear any tools away from the rotation area of the motor shaft.
• Turn on the power supply to test. If the motor runs smoothly, evenly, and stably, the connection process is complete.
• Finally, reinstall the terminal box cover and tighten the 4 screws for safety protection.
