Current carrying capacity
Max. cable length
Use flexible cables with a cross-section of 0.25 to 2.5 mm
wiring the power supply according to the maximum current that flows.
If you only use one wire per connection, an end sleeve is not required.
You can use end sleeves without an insulating collar in accordance with DIN 46228, Form A
long version.

X2 PROFINET

Data Transmission Rate and Cables
For PROFINET, you require a data transmission rate of 100 Mbit/s (Fast Ethernet). The
interfaces are designed for full-duplex mode; in other words, the ports can both transmit and
receive. For data transfer purposes you can use electrical twisted copper cables (twisted
pair, 4-wire, 100Base-T):
● The transmission characteristics of these cables must meet the requirements of CAT5.
● The maximum length of the connections between the end device and network component
