Fan configurations
The drive can be equipped with a non-redundant or a redundant fan configuration. The non-
redundant configuration consists of two fans, one for the integrated transformer (1 in Fig. 3-
14) and one for the inverter of the drive (2 in Fig. 3-14). The redundant configuration comprises
two fans for the integrated transformer and two fans for the inverter. This configuration
ensures that the operation of the drive is not interrupted if any single fan fails.

connect or disconnect the 3-phase auxiliary power. The AC fan speed is not controlled.
-
EC fans
: The electronically commutated (EC) fans are controlled via an analog signal from
the drive based on the inverter current. The EC fan speed is controlled depending on the
required cooling.
