Installation
Conductor cross sections between 0.08 mm 2 and 2.5 mm 2 can continue to be used with the proven spring
force technology.
The overview and nomenclature of the product names for KSxxxx and ESxxxx series has been retained as
known from KLxxxx and ELxxxx series.
High Density Terminals (HD Terminals)
Fig. 29: High Density Terminals
The Bus Terminals from these series with 16 connection points are distinguished by a particularly compact
design, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massive
conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal
point without tools.
Note
Wiring HD Terminals
The High Density (HD) Terminals of the KLx8xx and ELx8xx series doesn't support steady
wiring.
Ultrasonically "bonded" (ultrasonically welded) conductors
Note
Ultrasonically “bonded" conductors
It is also possible to connect the Standard and High Density Terminals with ultrasonically
"bonded" (ultrasonically welded) conductors. In this case, please note the tables concern-
ing the wire-size width [
