Information
Overview in the manual
The footprint braking resistors provided by the NORD DRIVESYSTEMS Group are directly tailored to
the individual frequency inverters.
For detailed information, please refer to the frequency inverter manual

Maintenance information
In order to ensure the dissipation of heat energy from the resistor body and the connecting cables, these
must be free from dirt during operation.
Due to temperature development on the resistor’s surface, deposits of flammable material must be
avoided in order to avoid ignition.
Cleaning of the resistor must be carried out with a dry duster on a regular basis when the resistor has
completely cooled down. The use of detergents for cleaning the resistor is generally not permitted.
For detailed information, please refer to the Maintenance and service information chapter in the BU 0600
manual, see
"Further documentation and software www.nord.com".

CAUTION
Overload
In case of overload, the braking resistor would be subject to significantly increased heat. Depending on
the overload degree, this may lead to overheating which permanently damages or even destroys the
braking resistor. As this can be accompanied by risk of fire for components in the vicinity of the resistor,
such overloads must be detected and avoided at an early stage.
• Use optional temperature switch
• Monitoring via parameter settings
