*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.

Main Circuit Wire Gauges and Tightening Torques
WARNING
Fire Hazard. Use terminals - and +3 for the braking resistor connections. If you connect a braking resistor to the
incorrect terminals, it can cause damage to the drive and braking circuit and serious injury or death.
Note:
•
The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class 2 heat-resistant indoor PVC
wire. Assume these conditions:
–
Ambient temperature: 40 °C (104 °F) maximum
–
Wiring distance: 100 m (328 ft) maximum
–
Normal Duty rated current value
•
Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options to terminals - and
+3. Contact Yaskawa or your nearest sales representative if the recommended wire gauges for the peripheral devices or options are out of
the range of the applicable gauges for the drive.
