Mains supply jumpers
These jumpers are used to adapt the SK 200E to various forms of mains supply (e.g. IT network). As
supplied, a star configuration earthed mains supply must be used, with an earth conductor for single phase
devices.
To adapt the SK 200E to an IT network, the capacitors C
y
must be disconnected from earth. 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 8.1. EMC.
2.6.5
Jumper Circuit Diagram
As supplied, the jumpers are set in the “normal position”. With this, the mains filter has its normal effect and
results in a higher leakage current.
