Main Circuit Wire Gauges and Tightening Torques
Refer to
6-Phase/12-Pulse 400 V Class on page 26
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 the drive is used.
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) or lower
–
Wiring distance: 100 m (328 ft) or shorter
–
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.
•
For drive models T208 to T720, 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.

Closed-Loop Crimp Terminals
To comply with UL standards on drive models T208 to T720, use UL-approved closed-loop crimp terminals and heat-
shrinkable tubing. Use the tools recommend by the terminal manufacturer to crimp the closed-loop crimp terminal.
Yaskawa recommends closed-loop crimp terminals and heat-shrinkable tubing from PANDUIT Corp.
Comply with local standards for correct wire gauges in the region where the drive is used.
Refer to
to select crimp terminals as specified by drive model and wire gauge.
Note:
To comply with UL standards, use only insulated crimp terminals or crimp terminals with insulation tubing. Use UL-Listed, vinyl-coated
insulated copper wires for operation with a continuous maximum permitted temperature of 75 °C at 600 V.
