The contact (pin) designations of the terminal blocks are - viewed in the installation position -
embossed directly under the contact points.
The permissible number of plugging cycles can be found in the following table.
Tabelle 12:
The alternatives given in the following table are allowed for the wire ends to be mounted in a
terminal block.
Tabelle 13:
1) in all applications, "straight (untwisted)" applies to the version without wire ferrule
and the current-carrying capacity decreases due to point contact instead of line contact of the stranded
wires.

When connecting the terminal blocks, ensure correct assignment in order to avoid damage to
the printed circuit board or the terminal block. A high plug-in resistance indicates that there is a
Check the upper end of the terminal block for a tight fit. If the assignment is correct, the terminal

It is recommended to use wire ferrules and to select them according to DIN 46228 and the
cable cross section used.
The line cross-sections must be dimensioned according to the maximum permitted current.
The wire ends must not have any burring or edges.
It is recommended not to twist strands (with and without a wire ferrule) since the stripping
length is shortened with twisting. In addition, the stability of the wire ferrule at the contact point
Due to the high contact density, DUO ferrules with several enclosed wire ends are not
permitted.
