Permissible line supplies dependent on the installation altitude

Permissible line supplies dependent on the installation altitude
● For installation altitudes ≤ 2000 m above sea level, it is permissible to connect the inverter
to any of the line supplies that are specified for it.
● 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
– The phase-to-phase voltage does not have to be reduced.
Note
Using Power Modules connected to TN line supplies with voltages ≥ 600 V for installation
altitudes 2000 m ... 4000 m
For voltages ≥ 600 V, the TN line supply must have a grounded neutral point established using
an isolating transformer.
