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.

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
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.
