Minimum short-circuit current
Derating for higher pulse frequencies on request.
1)
The maximum DC link capacitances of the drive line-up are specified as a function of the number of precharging resistors
2)
(2.2 Ω) connected in parallel per phase: 1 precharging resistor/2 precharging resistors/3 precharging resistors.
The specified power loss is the maximum value at 100 % utilization. The value in normal operation is lower.
3)
The cable lengths are valid for use in IT systems. When used in TN systems, the cable lengths are shortened to 30 % of
4)
the specified value.
When used in TN systems and during operation of the Active Line Module Chassis-2 or the connected Motor Module with
5)
increased pulse frequency, you can obtain the permitted cable lengths on request.
It is mandatory that the specified fuses are used to achieve a UL-approved system.
6)
Minimum current required for reliable triggering of the designated protective devices.
7)
When using fuses connected in parallel in each phase, all of the fuses must be replaced if one fuse trips.
