*3
The control circuit is a Safety Extra-Low Voltage circuit. Separate this circuit from other circuits with reinforced insulation. Make
sure that the Safety Extra-Low Voltage circuit is connected as specified.
*4
Reinforced insulation separates the output terminals from other circuits. Users can also connect circuits that are not Safety Extra-Low
Voltage circuits if the drive output is 250 Vac 1 A maximum or 30 Vdc 1 A maximum.

Control Circuit Wire Gauges and Tightening Torques
NOTICE
Do not let wire shields touch other signal lines or equipment. Insulate the wire shields with electrical tape or
shrink tubing. If you do not insulate the wire shields, it can cause a short circuit and damage the drive.
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.
