Direct cable connections: solid or stranded conductor with connector sleeve;
conductor with cross-section of 2.6 mm
tion end of the line into the plug-in terminal in such a way that it can be tightened cor-
rectly by the terminal screw.
Use copper wires only!
Strip 10 to 11 mm of the insulation on solid conductors
Maximum tightening torque: 2.7 Nm (2.0 ft-lb or 24 in-lb).
Short-circuit links are available for convenience in making terminal connections.
The short circuit links can connect two neighbouring terminals located on the same
side of the terminal module. By connecting further links, neighbouring terminals can
be included in the short circuit. On each terminal it is possible to connect two short-
circuiting links, or one short-circuit link and one lug, or one individual conductor.
The links meet the safety requirements for protection against electric shock.
There are two types of links, one for voltage connections and one for current connec-
tions. The links are illustrated in Figure 2-12. Ordering information for the links is pro-
vided in Section 1.1 in the Appendix A.

Terminal covering caps are available for the screw terminal modules, to increase the
protection of personnel against hazardous voltages (degree of protection against ac-
cess to dangerous parts) on the terminal modules. The degree of protection is in-
creased from the standard "back of the hand protection" (IP1x)" to „finger protection
(IP2x)".
The terminal covering caps provide an enclosure which securely covers all voltage
carrying components. They are simply snapped onto the terminal module. It must be
noted that all screws on the terminal module must be screws in before snapping the
cover on. The terminal covering cap can simply be removed with a screw driver 6x1
mm.
There are two types of covering caps, as shown in Figure 2-13. Ordering information
is provided in Section 1.1 in the Appendix A.
