Types of installation
The devices can be installed in the following ways:
● Installation on a 35 mm DIN rail
● Installation on a SIMATIC S7-300 standard rail
● Wall mounting
WARNING
Ambient temperature between 55 °C and 60 °C
If a device is operated in an ambient temperature of more than 55 °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
55 °C.
WARNING
If a SCALANCE X108PoE is operated at ambient temperatures between 55 °C and 60 °C,
there must be a minimum clearance of 40 mm to neighboring modules.
WARNING
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 to 60 °C, only use cables with admitted maximum operating
temperature of at least 80 ℃.
WARNING
Protective measures need to be taken to ensure that the rated voltage of the equipment
cannot be exceeded by more than 40% by transient surges. This is achieved by operating
the equipment only with SELV circuits (previously also PELV). Under no circumstances
must transient surges exceed 119 V.
Note
When installing and operating
the device, keep to the installation instructions and safety-
related notices as described here and in the manual "SIMATIC NET Industrial Ethernet
Twisted Pair and Fiber Optic Networks".
Note
Provide suitable shade to protect the device against direct
sunlight. This avoids unwanted
warming of the device and prevents premature aging of the device and cabling.
