■ Control Circuit Wire Gauges and Tightening Torques
Use the tables in this section to select the correct wires. Use shielded wire to wire the control circuit terminal
block. Use crimp ferrules on the wire ends to make the wiring procedure easier and more reliable.

Crimp Ferrules
Attach an insulated sleeve when you use crimp ferrules. Refer to Table 3.13 for the recommended external
dimensions and model numbers of crimp ferrules.
Use the CRIMPFOX 6, a crimping tool made by PHOENIX CONTACT.
