3.3 DC distribution network according to
IEC 61326-3-1
A DC distribution network is a DC power supply network which supplies a complete
industrial hall with DC voltage and to which any device is connected. A typical system or
machine distribution is not a DC distribution network. For devices that are intended for a
typical system or machine distribution, the DC connections are viewed and tested as I/O
signals according to IEC 61326-3-1.
3.4 Terminal point assignment
Figure 3-2 Terminal point assignment
The Axioline F connectors are supplied with the module. They are color coded and marked
for connection.
The following applies for the tables below:
– All outputs are safe digital outputs
– 0 V (GND): common ground of outputs
– FE: common functional earth ground
Table 3-1 Terminal point assignment of the voltage connection
NOTE: Damage to module electronics
A surge voltage will damage the module electronics.
• Do not use a DC distribution network.
