Please note:
Figure 34 shows the front connection of the external power supply circuits
(PSC 1, PSC 2).
It is also possible to implement the WAGO connector blocks (S

, S
2
) for rear
connection of the power supply circuit. In this case the subrack power cables
leave from the front and the plus/minus polarities on the WAGO connector
block appear reversed compared to the presentation in Figure 34.
