Power supply
Connecting the power supply
The power supply is connected using a 3- or 4-pin plug-in terminal block. Usable cable cross-
section 0.25 to 2.5 mm
2
. Permitted tightening torque 0.57 - 0.79 Nm (5 - 7 in.lb.).
The power supply is non-floating. The signal cables of the Ethernet TP ports are floating.
Note
Removing or inserting the power supply with the power on is not permitted.
Coding
With the SCALANCE X204RNA EEC the supplied plugs and the socket on the device for the
power supply match in their coding.
The plug and socket for the signaling contact are coded differently from the connection of the
power supply. The plugs for power supply and signaling contact cannot therefore be
interchanged.
You can use non-coded plugs in coded sockets and coded plugs in non-coded sockets.
