12 • The WAGO-I/O-SYSTEM 750 Power supply
2.4.1System supply voltage
The system supply voltage (24 V DC) is filtered with a voltage regulator before powering the coupler electronics as well as to the internal bus. Electrical isolation from the external fieldbus system depends on the type of Coupler/Controller.
The internal bus includes the internal communication between the coupler/controller and the bus modules as well as the power supply for the bus modules. The power supply is limited to a maximum value. This value depends on the type of Coupler/Controller. If the sum of the internal power consumption of all bus modules exceeds this value, it is necessary to add additional internal system supply modules (Order-No. 750-613).
The control electronics in the bus modules are powered by snap-fit mounting the bus modules using the internal bus contacts. A reliable contact is assured by the gold plated, self cleaning slide contacts. The removal of a bus module will cause an interruption in communication to the following bus modules.
The coupler/controller identifies the interruption point and displays a corresponding fault message.
Warning
Removing or inserting the I/O modules with the voltage applied can lead to undefined conditions. For this reason only remove the I/O modules when isolated from the power supply!

Power supply
2.4.2Supply Voltage Field Side
The voltage is automatically supplied when the I/O modules are snapped together. Self-cleaning power jumper contacts (P.J.C.s) ensure safe connections. The current capacity of the power contacts is 10 A max.
The PE contact is a preceding ground (earth) contact corresponding to the standards which can be used as a protective earth. The contact has a leakage capacity of 125 A.
Warning
Produce a low impedance connection from the carrier rail to the PE contact point in the cabinet.
Attention
Depending on the I/O function, some modules do not have P.J.C.s. It is important to note this when assembling a node. Many modules require field side power, many do not. Please review the circuit diagrams of the individual modules. An additional power supply module may be necessary.
Refer to the individual terminal/module data sheets!
When adding a power supply module, the field supply is always interrupted at the power contacts. From this point a new power supply is made, which can also include a potential change. This feature guarantees a high degree of system flexibility.
