Permissible line supplies dependent on the installation altitude
● Installation altitude is up to 4000 m above sea level.
● Output voltage is reduced above an installation altitude of 2000 m.
● For installation altitudes ≤ 2000 m above sea level, it is permissible to connect the converter
to any of the line supplies that are specified for it.
● For installation altitudes 2000 m to 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.
