Connecting the power supply
Note
As the epGate PA and epGate PB does not supply power to the PROFIBUS PA connections,
each PA segment of your PROFIBUS network requires its own power supply with power
conditioning (such as power conditioner R.STAHL 9412).
Connect the gateway 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.

Note
As the connection diagrams show, the power can also be applied by a special DIN rail
connector (Rail Power Supply). For further information contact
