Operating ranges
The following table provides information on the development of overtemperature with continuous power:
| Operating range | Explanation | 
|---|---|
| Normal:  | Recommended operating range for maximum lifetime with error-free operation | 
| Permissible:  | Still permissible operation with short service life and high failure probability | 
| Impermissible: Over 160% | Risk of destruction of the brake resistor due to overheating and endangerment of the surrounding components due to high temperature |
