Connection to AC supply

• Connection to an AC mains supply may only be carried out by qualified personnel!
• Cable cross section must be suitable for the maximum input current of the device (see tables below)!
• Before plugging in the input plug ensure that the device is switched off by its mains switch!
• The PE conductor is imperative and must always be wired!
• It is recommend to always connect all three phases, even if the device doesn't require them,
because then no phase can be missing
2.3.4.1 European models for 400 V
The equipment 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 labelling on the plug and the table below.
Required for the mains connection are following phases:
Nominal power Phases
3.3 kW / 5 kW L2, L3, PE
6.6 kW / 10 kW L1, L2, L3, PE
15 kW L1, L2, L3, PE
>15 kW L1, L2, L3, PE
For the sizing of wiring cross section, the power of the device and the cable length are decisive. The table below
gives the maximum input current for each phase.
Based on the connection of a standalone unit:
Nominal power
3.3 kW
5 kW
6.6 kW
10 kW (except for 40 V models)
10 kW (40 V models)
15 kW
The included connection plug can receive lose/soldered cable ends of up to 10 mm² resp. cable end sleeves up
to 6 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 or use bigger cross section.
