2.3.4 Connection to AC supply
• ConnectiontoanACmainssupplymayonlybecarriedoutbyqualiedpersonnel!
• Cable cross section must be suitable for the maximum input current of the device (see table
below)!
• Before plugging in the input plug ensure that the device is switched off by its mains switch!
The device is delivered with a 5 pole mains plug. Depending on model, this will be connected with a 2-phase or
3-phase mains supply, which has to be connected according to the description on the plug and the table below.
Required for the mains connection are following phases:
Nominal power Phases Supply type
3.3 kW / 5 kW L2, L3, PE Three-phase
6.6 kW / 10 kW L1, L2, L3, PE Three-phase
15 kW L1, L2, L3, PE Three-phase
>15 kW L1, L2, L3, PE Three-phase
For the sizing of wiring cross section, the power of the device and the cable length are decisive. The table below
gives the maximum output current for each phase

The included connection plug can receive cable ends of up to 4 mm². The longer the connection cable, the higher
the voltage loss due to the cable resistance. Therefore the mains cables should be kept as short as possible.
