Technical data
General data
Design D7
Conductor cross section 4 mm² ... 10 mm²
Connection cross section AWG 10 ... 8
Stripping length of the individual wire 8 mm +1
Assembly instructions
-The axial screw connection must be established using a 2 mm Allen
wrench.
-Use only stranded wires for axial screw connection.
-Plug-in connections may only be operated only when there is no load/
voltage.
Connection
Note regarding axial connection technology:
Only for stranded wires. The specified conductor cross sections refer to
the geometric cross section of the cable used.
Use of cables with a geometric cross section very different from the
cable's nominal cross section should be checked before use.
The wiring space of the axial screw method is established for fine strand
cables in accordance with VDE 0295 Class 5. Deviating cable structures
(e.g., Class 6 cables) should be checked before use.
Assembly instructions
Before assembly, ensure that the tapered screw is turned back all the way
(chamber is open). The cables must not be twisted.
The wires should be inserted as far as they will go into the contact
chamber (until the insulation touches the contact). Hold the wires in
position and use the socket wrench to tighten. The used wire end should
be cut off before connecting again. The connection screw may only be
retightened once to prevent the litz wires from breaking. To prevent
damage to the contact, the wire/cable should be mechanically intercepted
at an appropriate distance from the connection point (e.g., by using a plate
cutout). DIN VDE 0100-520:2003-06 contains information on how to do
this correctly. When not using PE contacts: set the PE contact as far as
possible in a clockwise direction.
