4.1.5 Wire cross sections (HD)
With the HD Terminals or Bus Couplers the wires are connected without tools in the case of solid wires
using the direct plug-in technique, i.e. the wire is simply inserted into the contact point after stripping the
insulation. The cables are released, as in the case of the standard terminals, using the contact release
with the aid of a screwdriver. The permissible conductor cross-sections can be taken from the following
table.
