Mounting and wiring
Pluggable wiring (ESxxxx / KSxxxx)
Fig. 22: Pluggable wiring
The terminals of ESxxxx and KSxxxx series feature a pluggable connection level.
The assembly and wiring procedure is the same as for the ELxxxx and KLxxxx series.
The pluggable connection level enables the complete wiring to be removed as a plug connector from the top
of the housing for servicing.
The lower section can be removed from the terminal block by pulling the unlocking tab.
Insert the new component and plug in the connector with the wiring. This reduces the installation time and
eliminates the risk of wires being mixed up.
The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3
mm. The maximum height of the terminal remains unchanged.
A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individual
connection wires when the connector is removed.
Conductor cross sections between 0.08 mm

The overview and nomenclature of the product names for ESxxxx and KSxxxx series has been retained as
known from ELxxxx and KLxxxx series.
High Density Terminals (HD Terminals)
Fig. 23: High Density Terminals
The Bus Terminals from these series with 16 terminal 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.
Wiring HD Terminals
The High Density (HD) Terminals of the ELx8xx and KLx8xx series doesn't support pluggable
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 below!
