Power supply 

Power supply 

The power supply is connected using a 4-pin plug-in terminal block.  
The power supply is connected over a high resistance with the enclosure to allow an 

ungrounded set up. The power supply is non-floating. The signal cables of the Ethernet TP 

ports are floating. 

SCALANCE X204 IRT PRO, X202-2P IRT PRO and X201-3P IRT PRO 

The power supply connector of the SCALANCE X204 IRT PRO, SCALANCE X202-2P IRT 

PRO and SCALANCE X201-3P IRT PRO is connected using a Power Plug PRO 

(PROFINET-compliant connector technology) 

These two devices also have two 24 V power connectors, one for the switched mode and 

one for the unswitched 24 V power supply (two plug-in power connectors). Using these 

power interfaces (L1+, N1 and L2+, N2), it is possible to loop through the power for ET200 

PRO with PROFINET-compliant connector technology. It is also possible to supply power to 

the module via an external T-piece (device supply over only one power interface). 
SCALANCE X204 IRT PRO, X202-2P IRT PRO and X201-3P IRT PRO 

Metal or plastic connectors (6GK1907-0AB10-6AA0) can be used for the power supply of the 

devices. 

 

Note 

 

If the devices are used in an ambient temperature in excess of 40 °C, or if currents higher 

than 6 A are conducted via the connector, metal connectors must be used. 

 

 

Note 
In areas subject to the National Electric Code (NEC), the Canadian Electric Code (CEC) and 

the EU directive 94/9 (ATEX), metal connectors must be used.
