SIMODRIVE 611 Planning Guide (PJU) – 05.01 Edition
2.8.5 Line supply types
The SIMODRIVE 611 drive converter system is designed for a rated voltage of
300 V phase–grounded neutral point.
It is not permissible that this voltage is exceeded, as otherwise the drive
converter insulation system could be damaged resulting in inadmissibly high
touch voltages.
!
Caution
The drive converter may only be connected directly to TN line supplies or
through an autotransformer.
For all other line supply types, an isolating transformer with grounded neutral
point on the secondary side must be used.
Note
UL requirements, maximum line short–circuit currents at 480 V AC:
S Connected power, 1.1 to 37.3 kW, max. short–circuit current = 5 kA
S Connected power, 39–149 kW, max. short–circuit current = 10 kA
