NOTE
In the case of line voltages which exceed the tolerance range specified in Section 3.4, the electronics
supply voltage and converter fan connection must be adjusted by means of transformers to the
permissible value stated in Section 3.4. It is essential to use an isolating transformer for rated line
voltages in excess of 460V.
The rated supply voltage for the power section is to be set in parameter P078 (index 001).

WARNING
The converter might overheat if the incorrect phase sequence is connected (incorrect direction
of rotation of fan).
Check: Check that the fan is rotating in the direction of the arrow!
Caution: Rotating parts can cause physical injuries!
