2.7.5 Mains supply jumpers
These jumpers are used to adapt the SK 2xxE to various types of network (e.g. IT network). As delivered,
the jumpers are plugged in the "normal position" (CY=ON) and are to be used in a network which is earthed
at the star point, with a neutral conductor for single phase devices!
To adapt the SK 2xxE to an IT network, the capacitors C
y
must be disconnected from the PE. This is carried
out by changing a jumper position as shown in the diagram.
Here it must be noted that the specified degree of radio interference suppression changes. Further details
can be found in Section 9.3 EMC.
