Voltage derating as a function of the installation altitude
In addition to current derating, voltage derating must also be considered at installation
altitudes > 2000 m above sea level.
Table 5- 21
Table 5- 22
Note
On systems with a grounded phase conductor and a line voltage > 600 V AC, measures
must be taken on the line side to limit overvoltages to overvoltage category II in accordance
with IEC 60664-1.
