Fig. 16: Standard wiring
The terminals of ELXxxxx series feature integrated screwless spring force technology for fast and simple
assembly.
High Density Terminals (HD Terminals)
Fig. 17: 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.
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 below!
