Refer to Three-Phase 200 V Class and Three-Phase 400 V Class for the recommended wire gauges and tightening torques of the main circuit terminals.
Comply with local standards for correct wire gauges in the region where you will use the drive.

Electrical Shock Hazard
Only connect peripheral options, for example a DC reactor or braking resistor, to terminals +1, +2, +3, -, B1, and B2.
Incorrect wiring 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 (3281 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 +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.
-
For drive models 2257 to 2415 and 4208 to 4H12, use UL-approved closed-loop crimp terminals on the drive main circuit terminals. Use the tools recommend by the terminal manufacturer and make sure that the terminals are correctly connected.
-
The metric wire gauge values are provided as reference information from equivalent AWG sizes and not exactly the same sizes as the AWG/kcmil values. Obey local safety regulations for wire sizes and make sure that the ferrule or crimp terminals are correct for your size.
