Sourcetronic ST600 Series - Grid Specifications; Motor Connection Data

Frequency Inverter ST600 Series High-Performance Multifunction VFD Technical data
-342-
B.2.2.2 Derating due to altitude
When the installation site altitude is lower than 1000 m, the VFD can run at the rated power. When the
installation site altitude exceeds 1000m, derate 1% for every increase of 100m; when the installation
site altitude exceeds 3000m, consult the local Sourcetronic dealer or office.
B.2.2.3 Derating due to carrier frequency
The power of frequency inverters ST600 high-performance multifunction VFD varies according to
carrier frequencies. The rated power of a VFD is defined based on the carrier frequency set in factory.
If the carrier frequency exceeds the factory setting, the power of the VFD is derated by 10% for each
increased 1 kHz.
B.3 Grid specifications
Grid voltage
AC 3PH 380V (-15%)–440V (+10%)
Short-circuit capacity
According to the definition of IEC 61439-1, the SP model VFDs 1R5G3–
015G3 are suitable for the use on the grid with the maximum expected
short-circuit current no more than 5kA at the maximum rated voltage; the
018G3–090G3 VFD models are suitable for the use on the grid with the
maximum expected short-circuit current no more than 22kA at the maximum
rated voltage; the 110G3–500G3 VFD models are suitable for the use on
the grid with maximum expected short-circuit current no more than 100kA
at the maximum rated voltage.
According to the definition in IEC 61439-1, the maximum allowable short-
circuit current at the incoming end is 100kA. Therefore, the VFD is
applicable to scenarios where the transmitted current in the circuit is no
larger than 100kA when the VFD runs at the maximum rated voltage.
Frequency
