Electrical supply
Page C.101
Weidmüller's tension clamp terminals have three
supply terminals:
ZEI 16 for standard terminals
ZEI 16/2-1AN for roof-type terminals
ZEI 6 for ZDU 1.5 …
Cross-connections divide the supply current into
several feeder currents.
Current is supplied across a conductor cross-sec-
tion of 16 mm
2
and then distributed across neigh-
bouring terminals for 1.5 mm

, 2.5 mm

, 4 mm

and 6 mm

cross-sectional areas.
Electrical distribution
Page C.103
A pluggable cross-connection system (ZQV) is
available for all Z series terminals.
The current is distributed across any number of
terminals by simply plugging the cross-connection
into the middle of the terminals. As a rule, 400 V
can be conveyed across the cross-section, de-
pending on the rated voltage of the terminal.
Testing
Page C.110
The slot-in test adapter (ZTA) is used as a single
unit and as a test adapter strip for voltage mea-
surement in switch cabinets. The test adapter is
ideal for convenient, rational testing of assembled
terminals. It is simply slotted onto the terminal. This
creates contact with the current carrying busbar.
The unit is released from the terminal simply by
pressing the release button.
Specific functions/colour variations
Page C.113
Further helpful accessories are available for termi-
nals using tension clamp technology, such as:
• Pluggable extra connections (ZZA)
• Housings for installation of electronic compo-
nents (ZBS 1)
• Pluggable fuse holder (SIHA 1 to SIHA 3)
• Terminals in various colours.
Fastening
Chapter F
An end bracket is fitted on the mounting rail to the
right and left of the terminals to ensure that they sit
firmly in position.
The marking surface of the end bracket can also
be used for group marking.
Details of the wide range of Weidmüller end brack-
ets and mounting rails are given in Chapter F.
Marking and connecting
Chapter M, chapter N, page C.112
Weidmüller's marking systems in chapter M are
used to mark tension clamp terminals. Individual
terminal points, terminal groups and conductors
can be marked.
The conductors are connected in the tension
clamp terminals with standard screwdrivers, as
shown in chapter N.
As an alternative to screwdrivers, fully insulated
operating tools are also available; see page C.112
