The infeed can be directly connected to a TN line supply for 3--ph. 400 V AC,
3--ph. 415 V AC, 3--ph. 480 V AC
1)
For other voltage levels, the infeed can be connected through an autotrans-
former.

Fig. 7-1 TN--C line supply connection schematic
Symmetrical 4--conductor or 5--conductor three--phase line supply with
grounded neutral point with a protective and neutral conductor connector con-
nected at the neutral point which, depending on the line supply type, uses one
or several conductors.
For other line supply types
2)
the NE module must be connected through
an isolating transformer.
1)
480 V direct connection is only possible in conjunction with the following PM (Order No.: 6SN1 12V-- 1 VV0V-- 0 VV>1)
and I/R modules (Order No.: 6SN1 14V-- 1 VV0V-- 0 VV>1) refer to Chapter 6.2.
For motors with shaft height < 100: Utilization, max. up to the 60 K temperature values according to Siemens
Catalog NC 60
Please observe the information and data in the Motor Configuration Manuals.
2)
Harmonized transformer types are described in Siemens Catalog NC 60.
