Note
In the case of line voltages that fall outside the tolerance range specified in Chapter 4, the
electronic supply voltage, exciter circuit line supply connection, and unit fan connection must
be adapted using transformers in order to comply with the value indicated as permissible by
Chapter 4. It is absolutely essential that you use an isolation transformer for rated line
voltages above 480 V for safe electrical isolation.
The rated supply voltage for the armature circuit (index 0) and for the field circuit (index 1)
must be set at p50078.
