Grounded TN/TT line supplies or non-grounded IT line supplies
Permissible line supplies (Page 72)
FSA ... FSC 1% ≤ Uk < 4%, for values smaller than 1%, we recommend a line reactor, or a
Power Module with the next higher power rating.
FSD ... FSG No restrictions
FSA ... FSC 0.7 without line reactor for Uk ≥ 1%
0.85 with line reactor for Uk < 1%
FSD ... FSG > 0.9
0 V 3 AC ... 0.95 x input voltage (max.)
50 Hz ... 60 Hz, ± 3 Hz
0 ... 550 Hz, depending on the control mode
< LO base load input current
III for line supplies
Factory setting
● 4 kHz for devices with an LO base load power < 110 kW
● 2 kHz for devices with an LO base load power ≥ 110 kW
Can be adjusted in 2 kHz steps as follows:
● 2 kHz ... 16 kHz for devices with an LO base load power < 55 kW
● 2 kHz ... 8 kHz for devices with an LO base load output of 55 kW ... 90 kW and ≥ 160 kW
● 2 kHz ... 4 kHz for devices with an LO base load power of 110 kW ... 132 kW
Current reduction as a function of the pulse frequency (Page 465)
If you increase the pulse frequency, the inverter reduces the maximum output current.
Maximum permissible line short-circuit current ≤ 100 kA rms
Minimum required short-circuit current ≥ 18 kA rms
The length of the connecting cable from the line to the inverter may not reduce the minimum
short-circuit current
