Motor cable
Yokogawa's motor cables are twisted pair cables with a common shield with the motor ground
cable. The shield is connected to the ground by connecting the motor ground cable to the
ground terminal.
If you provide your own cable, make sure to connect the shield to the ground terminal.
The tightening torque of the terminal block screw is 1.8 N-m and the matching wire size is
AWG#10 to 12. If a wire whose size does not match this specification is connected to the
terminal block, be sure to use a crimp terminal of the UL or CSA standard that matches the
wire size. Use crimp tools specified by the manufacturer.
