Installation using power-through daisy chain
The SINAMICS G110M system has been designed to allow a converter to utilize power-
through to provide the mains power for a number of converters in a daisy chain.
The maximum current limits for the daisy chain are given below:
● For the HanQ variants the maximum current of the daisy chained converters must not
exceed 16 A.
● For the Glanded variants the maximum current on the daisy chained converters must not
exceed 12 A.
● For both HanQ and Glanded variants the input for the daisy chained converters can be
protected by a 20 A fuse.
It is the users responsibility to ensure that the current limits are not exceeded.
The methodology for daisy chaining a number of Inverter is shown in the following diagram.
