The drive converter can be directly connected to TN line supplies at 3–ph.
400 V AC, 3–ph. 415 V AC, 3–ph. 480 V AC
1)
An autotransformer can be used to connect the drive converter to other voltage
levels.

Note
When using an autotransformer or an isolating transformer upstream from
NE modules (module width  100 mm), an overvoltage limiting module should
be used, Order No.: 6SN1111–0AB00–0AA0, refer to Section 7.
Symmetrical 4–conductor or 5–conductor three–phase line supply with
grounded neutral point which can be loaded with a protective and neutral con-
nector connected at the neutral point – depending on the line supply, realized
using one or several conductors.
1)
Direct connection to 480 V is only possible in conjunction with the following PM (Order No.: 6SN112V–1VV0V–0VV1)
and I/R modules, Order No.: 6SN114V–1VV0V–0VV1 refer to Section 6.1
For motors with shaft height < 100: Utilization up to max. 60 K temperature values according to Catalog NC 60
Please observe the information in the Planning Guide, Motors.
