Intensity regulator
Changing connection of the converter primary
Depending on the voltage available at the outlet it will be also required to change the connection of the
converter primary which is fixed to the electrical panel inside the the machine box as shown in section A2.
Electrical Box on the Technical Annex.
If the machine is connected to a 400V three-phased power supply it is necessary that the power connection
of the transformer primary is made between terminals labeled "0V" and "415V". In case of having a230V
outlet drive, then disconnect the power cord from the terminal "415V" of the transformer primary using a
screwdriver and connect it to terminal "230", right afterwards tighten the clamping screw with the
screwdriver.

Adjusting Intensity of engine-keeper
Depending on the line voltage the current consumption varies the of the machine. It is therefore necessary
to adjust the labor intensity of thermal motor protection. The rangers engine is fixed to the electrical panel
inside the cabinet of the machine, as shown in section A2. Electrical Box, on the Technical Annex.
To adjust the intensity of the engine-keeper simply turn the knob located on the front, using a Phillip
screwdriver, positioning the indicator arrow at the correct intensity.
In case of having a three-phased outlet 400V drive the engine-keeper must be set at an intensity of "2.6A".
On the contrary, in case of having a three-phased outlet 230V drive the engine-keeper at an intensity of
"5A".
If the engine-keeper installed can not be adjusted to the required intensity, it must be replaced by one with
a higher amperage.
