WQV screw cross-connector
When used together with W-series termi-
nals, WQV insulated cross-connection
units guarantee absolute safety for finger
and back-hand in accordance with the
accident prevention regulation “Electrical
systems and equipment” (VGB4).
It is very easy to produce individual config-
urations thanks to the many different op-
tions offered by the WQV cross-connec-
tion system, by breaking out individual
segments, creating any required number
of poles or routing two potentials in paral-
lel, etc.
Technical instructions
• The full rated current of the terminals
can be routed across any number of
poles.
• No end plates or partition plates needed
for adjacent WQV up to 400 V.
Assembly
• Place the WQV in the cross-connection
channel in the middle of the terminal
and screw tight.
• Individual WQV segments can be bro-
ken out by bending over or using the
WAW1 tool. It is then possible to bridge
individual or several terminals.
• Captive fixing screws.
• Snap onto the clamped support – sim-
ple overhead assembly.
Any number of poles (extending)
Pre-fitted cross-connectors can be set
one after the other to produce any re-
quired number of poles.
To do so, arrange the last and first contact
points of two identical WQVs so that they
overlap.
• First, remove the fixing screw and
screwdriver guide (insulated part) at one
of the outer contact points of one of the
WQVs.
• Then insert the WQV without fixing
screw and insulated part. At the same
time, insert an unmodified WQV in par-
allel so as to produce an overlap at the
connection. The connection is screwed
tight using the fixing screw of the un-
modified WQV.
Routing 2 potentials in parallel
• In spite of only having 1 channel, the
WQV cross-connection system can still
be used for offset cross-connections.
See the photo “parallel skipping”.
WQV in combination
with a socket contact and test plug
• Remove the fixing screw and insulation
part of the WQV.
Screw the socket in at this point. This
now makes it possible to integrate a
safe test point.
