Connecting a power supply adapter 

Input voltage options 

The optional power supply adapter is available in two versions: 

●

 

Power supply adapter for 12 to 24 VDC direct voltage 

Power Supply PS791-2DC 

Order number: 6GK5 791-2DC00-0AA0 

●

 

Power supply adapter for 100 to 240 VAC alternating voltage 

Power Supply PS791-2DC 

Order number: 6GK5 791-2AC00-0AA0 

 

 

Note 
Applies only to SCALANCE W786-2 
If a SCALANCE W786-2 is operated with six external antennas, the power supply for 12 to 

24 VDC cannot be supplied redundantly. In this case, there is no further opening in the 

housing for a second power cable. 

 

 

WARNING 

Danger from line voltage 
Only electrical specialists may open the device and connect the power supply adapter. 
Connect or disconnect power supply cables only when the power is turned off. 
Start the SCALANCE W786 only when you have screwed down the housing cover again so 

that there is once again protection against touching live parts.
