Figure 2-13 2-pin connector and 3-pin connector
Ordering information for the pin connectors is provided in Section A.1 of the Appendix.
The design of the pin connectors is such that only correct connections can be made.
For example, the design of the 2-pin connector allows connection only to pins “a” and
“b”. An erroneous connection to pins “b” and “c” is excluded.
The pin connectors snap in to the plug-in terminals. The connectors can be removed
without tools.
Control wires are connected to contacts of the pin connectors. Wires with 0.5 mm

diameter (AWG 20 to 13) can be accommodated.
Use only flexible copper control wire!
The crimp connector required depends on the diameter of the conductor being used.

After the wires are crimped, the contacts are pressed into the terminals of the connec-
tor until they snap into place..
