Measuring device for line supply variables with PROFIBUS connection

The measuring device is installed in the cabinet door of the Line Connection Module. The
measuring device senses power supply variables. In addition, other system values are
calculated from the measured values, e.g. power, power factor and other values. The
measuring instrument has a PROFIBUS interface that enables a transfer rate of up to 12 Mbit/
s.
Note
You can find a description in the "SINAMICS S120 Cabinet Modules" Manual, Chapter,
"Options / P11, measuring device for line supply variables with PROFIBUS interface, mounted
in the cabinet door".

Motor reactor

Motor reactors reduce the voltage stress on the motor windings. This is achieved by reducing
the voltage gradients at the motor terminals that occur when motors are fed from converters.
At the same time, the capacitive charge/discharge currents that also occur on the output of
the Motor Module when long motor cables are used are reduced.
Note
You can find a description of the motor reactor in the "SINAMICS S120 Cabinet Modules"
Manual, Chapter, "Options / L08/L09, motor reactor/2 motor reactors in series".
2.6.22

Line connection from above

The cabinet unit has an additional canopy. The connection lugs for the power cables, the
clamping bar for mechanically securing the cables, an EMC shield bus, and a PE busbar are
located within the hood.
Note
You can find a description of the canopy in the "SINAMICS S120 Cabinet Modules" Manual,
Chapter, "Options / M13, line connection from the top".
