Notes on installation

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 ℃.
NOTICE
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.
Suitable cables for temperatures in excess of 70 °C
If the cable or conduit entry point exceeds 70 °C or the branching point of conductors
exceeds 80 °C, special precautions must be taken. If the equipment is operated in an air
ambient in excess of 50 °C, only use cables with admitted maximum operating temperature
of at least 80 °C.
Provide suitable shade to protect the IE Switch X-300 against direct sunlight. This avoids
unnecessary warming of the IE Switches X-300 and prevents premature aging of the
IE Switch X-300 and cabling.
Note
When installing and operating the device, keep to the installation instructions and safety-
related notices as described in this document and in the manual SIMATIC NET Industrial
Ethernet Twisted Pair and Fiber Optic Networks.
