Table 6: Technical data chassis braking resistor SK BR2-...
The chassis braking resistors (SK BR2-…) listed above are equipped with a temperature switch at the
factory. Two different temperature switches with different triggering temperatures are optionally
available for bottom-mounted braking resistors (SK BRU5-…).
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 "Quick Stop".
NOTICE
Impermissible heating
If the bottom mounted braking resistor is mounted below the frequency inverter, a temperature switch
with a nominal switch-off temperature of 100°C (Part No. 275991200) must be used. This is necessary
to prevent impermissible heating of the frequency inverter.
• Failure to observe this may result in damage to the cooling system of the inverter (fan).
