2.8.2 Chassis braking resistors
Various sizes of the chassis braking resistors SK BR2-xxx/xxx-C are available for both frequency
inverter series (SK 700E and SK 5xxE) and all available frequency inverter power levels up to
160.0 kW. There are two types/sizes, type 1 and type 2. The chassis braking resistors or resistor
elements are integrated into a housing grating and can be used universally. The chassis braking
resistors come with an integrated temperature sensor (bimetal) ex-factory. The temperature sensor
can be connected to a digital input of the frequency inverter with two terminals (4 mm²), and one of the
safety functions ("Block voltage" or "Emergency stop ") can be programmed.
Both chassis braking resistor versions are UL-approved and, because of their protection class IP20,
can also be installed outside the switch cabinet for improved heat dissipation. For this purpose, the
chassis braking resistors have to be connected to the respective frequency inverter via a separate
connection cable, a shielded cable is recommended. The connection cable should be as short as
possible.
Information Chassis braking resistors
As the chassis braking resistors SK BR2 -xxx/xxx-C are used for both series of frequency inverters (SK 5xxE and
SK 700E), there is no allocation to the frequency inverter power levels in the present chapter.
Information Technical Information
For more details regarding the resistances, continuous power specifications and dimensions of the braking
resistors, please refer to the respective manuals (BU 0700 and BU 0500 or BU 0505).
