• Use terminals +1 and - to connect a regenerative converter or regenerative unit.
WARNING! Fire Hazard. Do not connect a braking resistor to terminals +1 or -. Use terminals B1 and B2 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.

Main Circuit Wire Gauges and Tightening Torques
WARNING! Crush 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 10mm
16 mm 2 (aluminum wire). The leakage current of the drive will be more than 3.5 mA in drive models;
• 2xxxB
• 2xxxC
• 4002B to 4371B
• 4002C to 4371C (with built-in EMC filter turned ON)
• 4389 to 4675
If you do not obey the standards and regulations, it can cause 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
• 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.
