X2 Profinet - Siemens SINUMERIK ONE NCU 1760 Equipment Manual

Wiring the screw-type terminal block
The required 24 VDC load power supply is wired to the screw-type terminal block (X1).
Danger of death caused by unsafe power supply
The 24 V direct voltage is to be configured as an extra-low voltage with protective separation
- DVC A or PELV according to EN 61800-5-1.
Power cables

Characteristics
Connection option
Current carrying capacity
Max. cable length
Use flexible cables with a cross-section of 0.25 to 2.5 mm
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 according to DIN 46228/1.

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
or between two network components (e.g. switch ports) must not exceed 100 m.
