The power supply line connecting the power cable to the electric box is three-phase five-wire with a voltage of 380V and a frequency of 50Hz.

The machine must be grounded.

After the power is connected, the direction of operation of the oil pump motor must be checked, and the hydraulic oil must be fully filled! Make sure the tank is full of oil before starting the pump. Attention should be paid to the specific operation:

1. Turn on the power switch.

2. Use the oil pump motor switch on the operation panel to start the oil pump motor and close it immediately.

3. Check whether the direction of operation is the same as the direction indicated by the arrow on the motor cover.

4. The power supply should be large enough to exceed the total power of the machine and the wiring should be thick enough.

If the direction is wrong, turn off the power switch on the machine and power supply line. Switch the power supply line L1 and L2. The missteering of the motor of the oil pump will damage the hydraulic oil pump. The oil pump motor can be closed by the switch button of the oil pump motor on the operation panel.
