The Braking Module is inserted in a slot inside the Power Module; it is force-cooled by the Power Module fan.

Several Braking Modules can be used for Power Modules with more than one power block:

• Frame size HX: 2 Braking Modules
• Frame size JX: 3 Braking Modules

Each Braking Module is always assigned a dedicated braking resistor.

The Braking Module is connected to the DC link by means of the busbar sets or flexible cables contained in the scope of delivery.

The Braking Module has the following interfaces as standard:

• DC-link connection
• Braking resistor connection
• 1 digital input (block Braking Module / acknowledge error)
• 1 digital output (Braking Module faulty)
• 1 DIP switch for adjusting the activation threshold

Information about Braking Module activation thresholds as well as further configuration information is contained in the SINAMICS Low Voltage Engineering Manual.
