Plug the connection end of the line into the plug-in terminal in such a way that it can
be tightened correctly by the terminal screw.
Strip 9 to 10 mm of the insulation on solid conductors
Maximum tightening torque
: 1.8 Nm (1.3 ft-lb or 16 in-lb).
Connections to
Current Terminals
Ring-type and fork-type lugs may be used. To ensure that the insulation paths are
maintained, insulated lugs must be used. Alternatively, the crimping area must be in-
sulated with other methods, e.g. by covering with a shrink sleeve.
The following must be observed:
Connections with cable lugs
: inner diameter of lugs, 5 mm;
maximum outer diameter of lugs, 12 mm;
conductor with cross-section of 2.6 mm
2
to 6.6 mm
2
(AWG 14 to 10).
Use copper wires only!
Cable lugs of series PIDG from AMP Co. are recommended, e.g.,
Ring cable lug: PIDG PN 130 171–0
Spade lug: PIDG PN 326 865–0
Direct cable connections
: solid or stranded conductor with connector sleeve;
conductor with cross-section of 2.6 mm
2
to 3.3 mm
2
(AWG 14 to 12). Plug the connec-
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 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.
