If the 400-volt power supply is without a neutral conductor, a single-phase transformer must be ordered in addition from the price list. The same transformer must also be ordered for a machine with a voltage higher than 400 volts, regardless of whether a neutral conductor is available or not. Machine version with 220 or 230 volts (50 or 60 Hz) is available at an additional cost (see price list).
