Operational altitude and altitude deratings

Voltage
The clearance within the converter can isolate surge voltages in accordance with
overvoltage category III in compliance with the EN 60664-1 regulation up to 2000 m above
sea level.
At altitudes above 2000 m and below 4000 m above sea level, the converter has to be
connected that at least one of the following conditions is fullfilled:
● It is connected to a TN-network with isolated star-point (not an external grounded
or
● it is connected through an isolating transformer that provides a TN-network with a
A reduction of the line voltage is not necessary.
Note: The connected engines and power components must be considered separately.
