WAGO I/O system 750 supply voltage
If the sum of the internal power consumption exceeds the sum current for bus modules, position a po-
tential feed terminal with bus power supply unit (750-613) upstream from the module where the admis-
sible sum current was exceeded.
Example:
In a node with a CAN bus coupler 750-337, 10 relay terminals (750-513) should be used. The power
consumption for this is 18 x 100 mA = 1800 mA. The coupler can provide 1650 mA for the bus modules.
Consequently, a potential feed terminal with bus power supply unit (750-613, max. 2 A output current)
must be added from the eighth terminal 750-513 of the node. In cases like this, a warning will tell you
of this situation when you are setting the parameters for the terminal.
You can check the configurations of the WAGO module using the free smartDESIGNER planning tool.

Attention
■
Please use a shielded, multi-core data cable for connection.
■
Route the data cable to other units separately from power lines.
■
Connect the shield of the data cable just once to the central earthing point (CEP) in the
control cabinet.
