Wire a New Drive
First remove the keypad, front cover, and control circuit terminal block of the newly installed drive. Wire the

• Do not twist the core wire of the electric wire. Failure to comply may result in a decrease in the clamping strength of the terminal
blocks.
• Do not shake the electrical wire excessively.
• Do not use wires in which the core wire is crushed or bent.
• Be sure to use only the wires with size, stripped wire length, and tightening torque specified by Yaskawa.
• Use tools that fit the shape of the screw head when tightening or loosening the terminal block screws.
• Confirm that there is no slack in wiring or that there are no frayed wires after the wiring process is completed.
