In the SINAMICS S120 Cabinet Modules, the built-in units of the SINAMICS S120 chassis format are integrated to provide a modular cabinet system for multi-motor drives with a central line infeed and a common DC link busbar for crane systems. As standard, they are installed side by side in a row.

The main components of the system in crane applications are as follows:

• Line Connection Modules with line-side components such as contactors, fuses and circuit breakers
• Line Modules for infeed in the Active Line Module version for four-quadrant mode with negligible line harmonic distortion and integrated line contactors
• Motor Modules in chassis format for controlling motors
• Switch-Over Modules for both economic and redundant combinations of motors and Motor Modules
• Motor Multi Connection Modules for parallel connection of motors for gantry drives in particular
• Motor Double Choke Modules for connecting a reactor between Motor Modules and motors when long cables are used, as is the case in gantry drives

The industry-specific version Cranes ordering option B70 is based on the requirements of the EN 60204-32 standard and implements the measures required for the cabinet units.

Specification in contrast to the available standard cabinet design:

• All auxiliary power supplies are routed to terminals for wiring in star topology
• Vibrational load in operation
  • Deflection 1.0 mm at 2 to 13.2 Hz
  • Acceleration 6.8 m/s? at 13.2 to 100 Hz
• The colors of the cores are in accordance with DIN EN 60204-32 except in the case of built-in Chassis Modules
• The complete documentation is supplied for the cabinets for the ordered configuration
• Internal wiring of the transport units
• Prepared wiring for easy assembly

When used in cranes, the industry-specific option B70 must be specified separately on ordering for all cabinets.
