For the W-series, power is supplied via standard
terminals in conjunction with a special cross-con-
nection, which directly connects terminals for larg-
er and smaller cross-sections (the picture shows
WDU 35 on WDU 4).
It is possible to form a link to screw-in cross-con-
nectors of smaller cross-sections (WQV 2.5/4/6).
This extends electrical distribution to any number
of other terminals of the smaller cross-section.

A screw-in and a pluggable cross-connection sys-
tem is available for Weidmüller screw terminals.
The pluggable cross-connector (ZQV) for screw
terminals is unique. It enables considerable reduc-
tions in assembly times. The pluggable cross-con-
nections can be used for nearly all W-series termi-
nals in the cross-section ranges 2.5 and 4 mm

Testing
Page D.82
Conductors are connected into Weidmüller termi-
nals using standard screwdrivers, as shown in
Section N.
The snap-in test adapter (WTA) is used as a single
slice and as a test adapter strip for measurements
in switchboards.
The test adapter is ideal for convenient, rational
testing of assembled terminals.
It is also possible to perform tests with a socket
contact and test plug (page D.79).

connection terminals including:
• Plug-in fuse holder (SIHA 1 and SIHA 2)
• Screen plug (LS), shorting plug (WDS)
• Extension connectors (WZAD)
• PEN bridges
• Accessories for measuring and isolating
terminals

Fastening
Page F.30
An end bracket is fitted to the right and left of the
terminals to locate the terminals on the mounting
rail.
The marking surface of the end bracket can also
be used for group marking.
Please turn to Section F for the wide range of
Weidmüller end brackets and mounting rails.
