3. Electrical Power Supply & Transformer Wiring

Point

Wire the transformer so that its voltage matches the power supply voltage.

Procedure

DANGER

Verify that the external power supply is off before

performing this procedure.

Connecting the Power Supply

The power capacities are indicated below. Be sure to connect the machine to a power

supply which exceeds this capacity.

• CP-732E : 8.5KVA

• CP-742ME: 9.0KVA

• CP-742E : 9.5KVA

1. Open the main breaker box, then remove the transparent terminal cover.

2. Feed the power cable into the main breaker box from the power cable inlet located

at the top of the main breaker 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 Connections

Perform the following procedure to verify that the three-phases are properly connected.

1. Turn the 200V power on.

2 Log in the machine.

3. Press the [AUTO] button (but do not press START).

Note: Do not press the START button.

The vacuum pump begins operating when [AUTO] is pressed, so disconnect the

hose to verify that suction exists. If there is suction, this indicates that the wiring is

correct and the motor is rotating in the correct direction. If the air flow is reversed

(air is blowing out instead of in), then turn the main power off and reverse the three-

phase power cable’s U-phase and V-phase connections, then try again.

Caution: To avoid leaks, the hose should be pushed firmly into position, and then secured in

position with the hose band.
