Minimum short-circuit current
The maximum DC link capacitances of the drive group depend on the number of precharging resistors (2.2 Ω) switched

in parallel per phase: 1 precharging resistors/2 precharging resistors/3 precharging resistors.
The specified power loss is the maximum value at 100 % utilization level. The value in normal operation is lower.
2)
The cable lengths are valid for use in the IT system. When used in the TN system, the cable lengths are shortened to

30% of the specified value.
When used in the TN system and during operation of the Active Line Module Chassis-2 or the connected Motor Module
4)
with increased pulse frequency, you will receive the permitted cable lengths upon request.
To achieve a UL-approved system, it is absolutely essential to use the fuse types specified in the table.

Minimum current required for reliable triggering of the protective devices.
6)
When using fuses connected in parallel in each phase, all of the fuses must be replaced if one fuse ruptures.

Overload capability

The Active Line Modules Chassis-2 provide an overload reserve.
The criterion for overload is that the Active Line Module is operated as a maximum with its
base load current before and after the overload occurs.
For the specified load cycles, it is possible that the applicable derating factors must be taken
into consideration (for example, pulse frequency, ambient temperature).
