Changing the hydraulic motor connection:
The motor of the hydraulic system is located inside the cabinet, at the bottom of the machine.
The hydraulic assembly is inside the cabinet. The motor is secured to the tank and on its front is the
connection box.
The same as the main motor, when the mains voltage is 400 V three - phase, proceed to connect in Star
form (as preinstalled at the factory). If the power supply is 230 V three - phase, proceed to connect in
triangular form. As indicated in the illustration.
It is necessary to change the configuration of the plates according to the voltage, as was done with the
main motor.
