Bypass 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 the crimp ferrules.
Use the CRIMPFOX 6, a crimping tool made by PHOENIX CONTACT.

Bypass Control Circuit Terminal Block Input Functions
WARNING! Sudden Movement Hazard. Correctly wire and test all control circuits to make sure that the control circuits operate
correctly. If you use a drive that has incorrect control circuit wiring or operation, it can cause death or serious injury.
WARNING! Sudden Movement Hazard. Check the I/O signals and the external sequences for the drive before you set the
Application Preset function. When you set the Application Preset function (A1-06
≠
0), it changes the I/O terminal functions for the
drive and it can cause equipment to operate unusually. This can cause serious injury or death.
NOTICE: Damage to Equipment. Do not energize and de-energize the bypass more frequently than one time each 30 minutes. If
you frequently energize and de-energize the bypass, it can cause failure.
