Note:
In the case of line supply voltages that fall outside the tolerance
range, the supply voltages for the electronics, field circuit, and
unit fan must be adapted to the permissible value using trans-
formers. An isolation transformer is absolutely essential for rated
line supply voltages above 480 V.
The rated supply voltage for the armature circuit (index i00) and
for the field circuit (index i01) must be set at p50078.
