Figure 3-24 Output current as a function of the installation altitude
At installation altitudes >2000 m, an insolating transformer must be used (see "System
overview/Derating as a function of the installation altitude and ambient temperature"). The
design of the secondary line supply system must be as follows:
● TN system with grounded star point (no grounded outer conductor)
● IT system
A reduction of the line supply voltage phase-phase is not necessary.
