Note
In the case of line supply voltages that fall outside the tolerance range (see Chapter
"Technical data (Page 39)"), the electronics supply voltage, field circuit line supply
connection, and the unit fan connection must be adapted to the permissible value using
transformers. It is absolutely essential that you use an isolation transformer for rated line
voltages above 480 V for safe electrical isolation.
The rated value of the supply voltage for the armature circuit (index 0) and for the field circuit
(index 1) must be set at p50078.
