Overtemperature

WARNING

Serious injuries due to hot surfaces

The housing surface may reach a temperature of over 200 °C. Failure to observe the protective measures may result in severe burns to the skin and the braking resistor or surrounding components may be destroyed.

  • Do not touch the surface of the housing during operation and allow to cool down after operation
  • Always ensure that the is sufficiently ventilated
  • For additional protection, we recommend a contact protection

At the housing surface

An application may require a higher continuous power than the specified type power. You can implement this state if a higher temperature of the braking resistor is permissible.

Operating ranges

The following table provides information on the development of overtemperature with continuous power:

Operating range

Explanation

Normal:
maximum 130 %

Recommended operating range for maximum service life with error-free operation

Permissible:
maximum 160 %

Still permissible operation with short service life and high failure probability

Impermissible: maximum 160 %

Risk of destruction of the braking resistor due to overheating and endangerment of the surrounding components due to high temperature
