3.1.3 Connecting the power supply
Note
As the mbGate PA gateway does not supply power to the PROFIBUS PA
connections (PA0 to PA3), each PA segment of your PROFIBUS network requires
its own power supply with power conditioning (such as power conditioner
R.STAHL 9412) and a field barrier for connecting to devices in explosive
atmospheres.
Connect the device to a 24 V DC power supply. The supply voltage (18 VDC .... 32 VDC) is
connected by a 3-pole terminal block. The power supply is connected to the plug connector
via flexible wires with a cross section of 0.75 to 1.5 mm². The ground connection wire must
have a cross section of 1.5 mm².

CAUTION
The Functional Earth (FE) connection of the device has to be connected at low
inductance with the Protective Earth (PE) of the system.
Note
As the connection diagrams show, power can also be applied by a special DIN
rail connector (Rail Power Supply). For further details contact Softing
