Changing of the hydraulic motor connections:
The hydraulic system motor is located in the inside of the cabinet, at the base of the machine.
The hydraulic group is located inside the cabinet, with the motor secured to the tank and the terminal box
located at the front of the machine.
Just like the main motor, when there is three-phase 400 V power voltage, we make the connection in a Star
shape (already pre-installed in the machine). If it is 230 V three-phase, we make the connection in a trian-
gle shape, as shown in the diagram.
The modification of the connection must be done in the same way as the main motor, changing the configu-
ration of the plates.

Change of the transformer connections:
Depending on the operation voltage required, the connections will also have to be changed in the transfor-
mer. This is located secured to the electrical panel inside the machine cabinet as shown in section A3.
Electrical cabinet
This is like the one shown in the diagram below. In order for the machine to operate at 400V, the inlet ter-
minals connected are identified as “0v” and “415v”. To modify the operation voltage to 230V, all you have to
do is release terminal “415v” using a star screwdriver and connect the released cable to the “230v” inlet
and tighten it with the screwdriver
.
