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

Cabinet design and EMC

11.6 Arrangement of the devices

11.6 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 PM21 or NC61
● Heat dissipation
● EMC
The components of the HF line-up must be mounted on the mounting plate described in
Chapter Installation (Page 55).
Components are usually located centrally in a cabinet. The necessary mounting and
installation clearances above and below the components can possibly exceed the minimum
clearances specified in the product documentation.

Cooling circuit and coolant properties

The cooling circuit is essentially designed as described in the following manual:
● SINAMICS S120 Manual for Booksize Power Units
In the corresponding chapters you will also find information on coolant properties.
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.
NOTICE
Damage to the component as a result of liquids that have entered
Liquids that penetrate the equipment can cause short circuits in the components and
damage the components.
• Use a rigid piping system when connecting the cooling circuit to the Motor Modules.
• Apply a thread locking compound/sealant to the screw connections of the cooling water
176
connections to prevent them loosening and leaking. Use Loctite 577 liquid thread
sealant and the associated Loctite 7091 activator. Carefully observe the application
instructions of the associated product description from Loctite.
