Wiring HD Terminals
The High Density (HD) Terminals of the KLx8xx and ELx8xx series doesn't support steady wiring.
Ultrasonically "bonded" (ultrasonically welded) conductors
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 concerning the
wire-size width [ } 28] below!

Fig. 23: Mounting a cable on a terminal connection
Up to eight connections enable the connection of solid or finely stranded cables to the Bus Terminals. The
terminals are implemented in spring force technology. Connect the cables as follows:
1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square opening
above the terminal.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is released, holding the wire securely and per-
manently.

High Density Terminals ELx8xx, KLx8xx (HD)
The conductors of the HD Terminals are connected without tools for single-wire conductors using the direct
plug-in technique, i.e. after stripping the wire is simply plugged into the contact point. The cables are
released, as usual, using the contact release with the aid of a screwdriver. See the following table for the
suitable wire size width.
