Table 7: Technical data, temperature switch for chassis braking resistor SK BR2-…
The chassis brake resistors (SK BR2-…) listed above are equipped with a temperature switch at the
factory.
In order to use the signal from the temperature switch it must be connected to a free digital input of the
frequency inverter and, for example, parameterised with the function "Voltage block" or "Fast stop".
