Derating due to installation altitude
The following applies to all drive controllers:
In S1 mode, no power reduction is required up to 1,000 m above sea level.
In the range from 1,000 m up to and including 2000 m, power reduction of 1%
is required for every 100 m installation altitude. An overvoltage category 3 is
observed!
In the range from 2,000 m up to and including 4,000 m, the overvoltage cate-
gory 2 must be observed due to the lower air pressure!
To comply with the overvoltage category:
an external surge protector should be used in the mains supply line to the
drive controller.
the input voltage should be reduced.
Please contact the manufacturer.
The respective max. output values can be defined, based on the following charac-
teristic curves.
