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!
2.3.5.1
Standard models for 380 / 400 / 480 V
The device is delivered with a 5 pole AC plug. This plug is connected to 3-phase AC supply, according to the la

The PE conductor is imperative and must always be wired!
The N conductor of a standard cable with 5 conductors is not required, but can be connected
to the free slot on the AC plug.
For the selection of a suitable cable
cross section
the rated AC current of the device and the cable length are
decisive. Based on the connection of a
single unit
the table lists the maximum input current and recommended
minimum cross section for each phase:

The included connection plug can receive crimped cable ends of up to 16 mm². The longer the connection cable,
the higher the voltage loss due to the cable resistance. Therefore the mains cable should be kept as short as
possible or have an even bigger cross section. Cables with 4 or 5 conductors can be used. When using a cable
with N conductor, it’s allowed to clamp it into the spare pin of the AC plug.
