System advantages
SAK/AKZ series
Stripping length
The required stripping length for all
Weidmüller products is specified in mm.
These lengths must be observed so that
the creepage and clearance paths are not
reduced due to improper connection.
Mounting
Mounting is carried out on TS 32 moun-
ting rails according to EN 50 035 or
TS 15 according to EN 50 045.
End plate
The last terminal of a mounted terminal
row must be closed with an end plate.
The end plate is held in place by the end
bracket.
Partition
Depending on the operating voltage, a
partition must be placed between neigh-
bouring cross-connection groups.
This is necessary to maintain the neces-
sary creepage and clearance paths.
Small partition
After assembly, small partitions can be
inserted between cross-connections or
sockets for terminal blocks with a max.
width of 12 mm.
Cover plates
Several VDE regulations require that the
supply connection terminals are labelled.
For this purpose, Weidmüller provides a
range of cover plates printed with a war-
ning arrow and the international danger
symbol. A warning arrow is printed on the
reverse side with the words Danger
Voltage. The cover plates are attached to
the terminals blocks with plastic screws.
The cover plates are designed to cover 3
or 4-pole terminal blocks.
Cross-connections
Cross-connection systems from the SAK
and AKZ series, type Q, QL or VL or other
freely accessible live components, must be
protected with appropriate covers ADP 1
to 4 or TSK 31.5 as long as they are to be
inserted safe from contact.
Frequently, several terminals blocks must
be electrically interconnected in order to
create supply pick-offs. Because the ter-
minal point usually needs to remain free for
the conductor connection, a cross-
connection bridge is placed in the middle.
For adjacent cross-connections with vary-
ing potentials, partitions, end plates or
small partitions must be inserted to main-
tain the nominal voltage. Cross-connection
bridges can normally carry half of the rated
terminal block current.
Weidmüller distinguishes between the fol-
lowing cross-connection units:
• type Q pre-assembled cross-connec-
• type QL permanent cross-connections
• type VL removeable cross-connection
• type QS removeable cross-connection
Sockets
In place of cross-connections, sockets can
be attached to accept test or short-circuit
plugs.
Test plugs
2.3 or 4 mm ø test plugs are available for
measurement and test operations .
Designation
Incoming and outgoing cables can be
labelled using various marking systems,
e.g. dekafix, snap-on tags, etc.

Safe testing of wired terminal blocks is a
basic requirement for fault-free functional
sequences. The WTA..., STA..., ATA... test
adapter systems for individual terminal
block ranges are not only characterised by
their quick and easy handling, but also
offer other advantages:
• conductor decoupling between the test
• spring-loaded test contacts ensure relia-
• locating hooks on both sides ensure firm
• the modular concept enables the con-
• single-pole test adpaters can be inter-
Naturally, customary sockets can also be
used whose test pick-off is performed by
spring-loaded test plugs. This option
applies even when cross-connections are
fitted.
