1)
The armature/field supply voltage may be lower than the rated armature/
field voltage (set by parameter). A minimum input voltage of 50 V is permis-
sible for units with a rated voltage of 400 V, 480 V and 575 V, or 85 V for
higher rated voltages. The output voltage is reduced accordingly. The
specified DC output voltage can be maintained up to an undervoltage of
5 % of the line supply voltage (rated armature/field supply voltage).
2)
Fan noise for a unit installed in an IP20 electrical cabinet (door closed,
50 Hz operation or operation at 24 V DC for units with an internal supply).
3)
For fan motor type R2D220-AB02-19 in units 6RA8081, 6RA8085, and
6RA8087 with a rated voltage of 400 V or 575 V, UL systems require a
Siemens motor circuit breaker of type 3RV1011-0DA1 or 3RV1011-0EA1,
set to 0.3 A.
