Types of installation
The Industrial Ethernet switches of the SCALANCE X-100 product line can be mounted in
different ways:
● Installation on a 35 mm DIN rail
● Installation on a SIMATIC S7-300 standard rail
● Wall mounting
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 /1/.
Unless stated otherwise, the mounting options listed below apply to all Industrial Ethernet
Switches of the SCALANCE X-100 product line.
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.
WARNING
If temperatures in excess of 70° C occur on the cable or at the cable feed-in point, or the
temperature at the branching point of the cables exceeds 80° C, special measures need
to be taken. If the equipment is operated at an ambient temperature of 50° C - 60° C,
use cables with a permitted operating temperature of at least 80° C and if equipment is
operated at an ambient temperature of 61° C - 70° C, use cables with a permitted
operating temperature of at least 90° C.
WARNING
Protective measures must be taken to avoid the rated voltage of the equipment being
exceeded by more than 40% by transient overvoltages. This is the case if the equipment
is supplied exclusively by SELV circuits.
