Safety notices
When installing the device, keep to the safety notices listed below.
If a device is operated in an ambient temperature of more than 50 °C, the temperature of
the device housing may be higher than 70 °C. The device must therefore be installed so
that it is only accessible to service personnel or users that are aware of the reason for
restricted access and the required safety measures at an ambient temperature higher than
50 °C.
If the device is installed in a cabinet, the inner temperature of the cabinet corresponds to
the ambient temperature of the device.
Ambient temperature for SCALANCE XR526-8C (AC 240V)
The SCALANCE XR526-8C (AC 240V) devices may only be operated above an ambient
temperature of 35 °C if they are in a restricted access location.
A restricted access location means that a device is, for example, installed in a control
cabinet and is only accessible to trained personnel.
Use only approved components
If you use components and accessories that are not approved for SIMATIC NET devices or
their target systems, this may violate the requirements and regulations for safety and
electromagnetic compatibility.
• Use only components that are approved for SIMATIC NET devices.
