2 INSTALLATION
After connecting electric power and compressed air, the machine is ready for use.
Power supply
Connect the machine to 3-Phase, 50/60 Hz, 440 V. The machine may be reset to 400 (380) V as follows:
Disconnect the power source from 440V outlet.
Open the machine by removing the handle and cover.
Remove cable no. 22 from 440V on the control transformer and connect it to 400V.
Reassemble the cover and handle.
Connect the power supply to 400V outlet.
NOTE: at least 30 kVA should be available from the generators exclusively for the plasma cutting system. If
available power is lower it may result in major damage to the power source.
If running the machine on 440V while set to 400V and vice versa may result in damage to the power source.
Air supply
Connect dry, clean and oil free compressed air with minimum pressure 6bar, maximum pressure 7 bar to
the filter regulator on the rear of the machine.
Note that the pressure gauge on the front of the UPC-1041 will not show any pressure until the air is
flowing, see Operating instructions.
