Detailed configuration instructions regarding the EMC-compliant design of drives and control
cabinet configuration can be found in the "SINAMICS Low Voltage Configuration Manual",
see Configuration Manual for SINAMICS G130, G150, S120 Built-in Units, S120 Cabinet

Mounting on mounting rails

The liquid-cooled SINAMICS S120 devices can be mounted in the control cabinet on
mounting rails. For this purpose, mounting rails are provided on the lower side of the power
units, which can be used to mount the device in the control cabinet.
The mounting rails are intended to simplify installing or removing the power unit (Active Line
Modules, Basic Line Modules, Motor Modules, Power Modules).
For this purpose, the mounting equipment for the power units can be attached to the
mounting rails (article number 6SL3766-1CA00-0AA0), in order to simplify mounting and
installation work, see "Mounting equipment for power units (Page 354)".
By suitably designing the mounting rails in the control cabinet, the mechanical load of the
power unit can be better distributed to the cabinet frame elements.
The mounting rails must be designed and manufactured on a system-for-system specific
basis.
Bolting points for the mounting rails
In order that the mounting equipment for the power units can be correctly attached to the
mounting rails, the mounting rails must be provided with the subsequently described bolting
points at the front.
