Mounting instructions
1 - Standard use
2 - Cut extremities
For voltage rating > 50 V and Uimp > 2.5 KV, the below
accessories must be installed on the cut side of the jumper
to guarantee IP20 and voltage rating:
ZS... Feed-through CS circuit separator
Double deck / triple deck ES… end section
ZK… All functions EK… end section
Ensure a good straight cut by positioning the cutting tool on
the vertical snicks of the insulated part of the jumper.
3 - Cut poles
4 - Alternated poles
5 - Alternated poles with cut extremities
When using cut jumpers, cut extremities should be placed
oppositely to allow end sections / circuit separators place-
ment at each cut extremities.
