The temperature on the exterior sidewall of the housing can deviate considerably from the
temperature in the control cabinet.
➤
The temperature on the exterior sidewall of the housing must be observed in a steady state.
➤
In case the temperature on the exterior sidewall of the housing is higher, the failure rates
from
„5.2.1 FMEDA results“ on page 9
must be adjusted:
➤
For a higher average temperature of 60 °C on the exterior sidewall of the housing, the failure
rates are multiplied by an experience factor of 2.5.
➤
Ensure that sufficient heat dissipation is provided.
➤
Protect the device from radiated heat and severe temperature fluctuations.
➤
Protect the device from dust, dirt, moisture, shock, vibration, chemical stress, increased radia-
tion and other environmental influences.
➤
Ensure a degree of protection of at least IP20 according to IEC 60529 at the mounting
location.
➤
Ensure that the electromagnetic stress does not exceed the requirements of IEC 61326-3.1.
➤
If there is a visible error, e.g. defective housing the device must not be used.
➤
During operation of the device, surface temperatures may occur that could lead to burns if
touched.
➤
The device must not be repaired. If problems occur with regard to functional safety, Turck
must be notified immediately and the device must be returned immediately to:
Hans Turck GmbH & Co. KG

A full assessment of the development process is carried out in accordance with EN 61508-
1:2010, EN 61508-2:2010 and EN 61508-3:2010.
The Siemens standard SN 29500 for 40 °C is used as the database for determining the key safety
figures (failure rates of the components, expected values).
The components used should be designed for a service life of 87600 h.
The safety-relevant use of the device is limited to control cabinets and switch boxes in typical
industrial environments.
