Main Circuit Wire Gauges and Tightening Torques

WARNING
Electrical Shock Hazard. Make sure that the protective ground wire complies with technical standards and
local safety regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the power supply to automatically
de-energize when the protective ground wire disconnects. You can also connect a protective ground wire that has a minimum
cross-sectional area of 10 mm
can cause serious injury or death. The leakage current of the drive will be more than 3.5 mA in drive models 2xxxB, 4xxxB, and
4317A to 4605A.
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 (3281 ft) maximum
–Rated current value
• Use terminals +1, +2, +3, -, B1, and B2 to connect a peripheral option such as a DC reactor or a braking resistor. Do not connect other
items to these terminals.
• Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options to terminals +1,
+2, +3, -, B1, and B2. 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.
