3.4 Connection between machine and main power supply
Caution: Only qualified technician can make a connection of main power supply. A
voltage of power supply for machine is as AC380V, if get an electric shock, it would
cause some damages of machine or might lead to injuries and deaths on people.
Must be in accordance to a circuit diagram to connect a power supply of
machine on an assigned wiring position. The machine must be in safety
grounding.

After connecting motor and electromagnet with control cabinet, then
checking a rotation of motor of oil pump, the rotary direction should be as the
same direction as the arrow point. The way to check the rotary direction of
motor: Press the start button of pump, then pressing the stop button at once.
See if the rotary direction is correct, if it is not, swap the places of 2 input power
wires of AC380V. Repeat doing as indicated above. Make sure that the rotary
direction of motor is correct. The motor of high pressure oil pump is counter
clockwise rotation, the motor of low pressure pump rotates clockwise.
Caution: Be sure never let the motor rotate on incorrect direction more than one
minute.
