Siemens SINAMICS G120C DP User Manual

• For installation altitudes 2000 m ... 4000m above sea level, the following applies:
– Connection to a TN line system with grounded neutral point is permissible.
– TN systems with grounded line conductor are not permitted.
– The TN line system with grounded neutral point can also be supplied using an isolation
transformer.
– The phase-to-phase voltage does not have to be reduced.
Current derating as a function of the installation altitude
The permissible converter output current is reduced above an installation altitude of 1000m.
