Figure 2-11 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 not possible.
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. AWG 20 to 13 wire
2 2
(0.5 mm to 2.5 mm diameter) can be accommodated.
Use only flexible copper control wire!
The crimp connector required depends on the diameter of the conductor being used.

Connection of a conductor to a contact is performed using a hand crimping tool, e.g.,
type 0–825582 from AMP Co.
After the wires are crimped, the contacts are pressed into the terminals of the connec-
tor until they snap into place.
Note:
Stress relief for individual pin connector must be provided with cable ties. Stress relief
should also be provided for the entire set of cables, e.g., cable ties.
The following separation tool must be used to remove the contacts from the pin con-
nectors:
Type: 725840–1 from AMP Co.
The separation tool contains a small tube that is subject to wear. The tube can be or-
dered separately:
