Connecting the Power Supply

DANGER

Verify that the external power supply is off before

performing this procedure.

1. Open the power box, then remove the transparent terminal cover.

2. Feed the power cable into the power box from the power cable inlet located at the

left side of the power box.

3. Connect the ground cable to the dedicated ground terminal.

4. Connect the 3-phase cable to the main breaker and tighten to the prescribed

torque.

Terminal screw tightening torque: 5.8 N⋅m (58 kgf⋅cm)

Note: Terminal screws should be tightened periodically.

5. After connecting the cable, secure it with the cable lock nut located at the power

cable inlet.

Cable lock nut tightening torque: 7.5 N⋅m (75 kgf⋅cm)

Checking the Three-Phase Cable Wiring

Follow the below steps to confirm that the three-phase wiring has been performed

correctly.

(1) Engage the 100 V power supply.

(2) Engage the 200 V power supply.

(3) Perform zero-setting.

(4) Press [AUTO]. Do not press the START button.

When [AUTO] is pressed, the vacuum pump in the noise reduction box at the rear of the

machine operates. Remove the hose to confirm that air is being sucked in. If air is being

sucked in, the wiring is correct and the motor is turning in the proper direction. If air is

being blown out, the user has crossed the U and V wires of the three-phase wiring.

Change these 2 wires and follow steps 1 to 4 again to confirm correct wiring.

Note: The CP-652C has a different shape of noise reduction box from the figure below. The

check procedure, however, is the same as stated above.
