Arrangement Of The Devices; Cooling Circuit And Coolant Properties - Siemens SINAMICS S120 System Manual

12.6

Arrangement of the devices

The arrangement of the components and equipment in the control cabinet takes account of:
• Space requirements
• Cable routing
• Bending radii of the connection cables
MOTION-CONNECT cables, refer to Catalog D21.4 or NC62
• Heat dissipation
• EMC
The components of the HF line-up must be mounted on the mounting plate described in Chapter
Installation (Page 61).
Components are usually located centrally in a cabinet. The necessary mounting and installation
clearances above and below the components can exceed the minimum clearances specified in
the product documentation.
Support relating to the mechanical control cabinet design is available from:
Siemens AG
Digital Industries, DI MC MF - WKC
TCCCC (Technical Competence Center Cabinets Chemnitz)

Cooling circuit and coolant properties

The technical documentation SINAMICS S120 "Booksize Power Units" Edition 06/2019
(6SL3097-5AC00-0AP2) describes the setup of the cooling circuit.
Note
Special features of the High Frequency Drive
• Only use shielded coolant hoses or metal coolant pipes when the routing coolant within the
EMC control cabinet.
• Connect the shields of the coolant hoses at both ends.
• You must install flow monitors to completely protect the devices.
Recommendation: efector300 SM6000 from the ifm electronic GmbH company
When the rated flow rate is fallen below, the pulses must be inhibited within 10 s.
