Dc Link Fuses; Parallel Connections Of Motor Modules - Siemens SINAMICS G130 Engineering Manual

DC link fuses

DC link fuses are integrated in the power unit of every Motor Module. When a DC coupling (option L37) is installed,
the fuses are integrated in the DC switch.

Minimum motor cable length for parallel connection
A cross-connection of the motor terminal lugs between the individual modules is not available. Combined terminal
lugs are available on request with an additional cabinet.

These data relate to units with supply voltages of 500 V to 690 V 3AC (MLFB 6SL3720- 1TGxx-xAA0) and 660 V to 690 V 3AC
(MLFB 6SL3720-1 THxx-xAA0).
If two Motor Modules are connected in parallel, imbalances in the current distribution can
occur despite the current compensation control. As a result, a derating factor of 5 %
applies to parallel connections. Parallel connections may only include Motor Modules with
identical voltage rating and identical output power rating.
For the purpose of decoupling, parallel-connected Motor Modules must be configured with
the minimum cable lengths specified below. The specified power ratings are the values for
a single Motor Module.
