C.3 UL Standards
Closed-Loop Crimp Terminal Recommendations
Note: Use crimp insulated terminals or insulated tubing for wiring these connections. Wires should have a
continuous maximum allowable temperature of 75 °C 600 V UL approved vinyl sheathed insulation.
Ambient temperature should not exceed 30 °C.
Yaskawa recommends crimp terminals made by JST and Tokyo DIP for the insulation cap.
Table C.6 matches the wire gauges and terminal screw sizes with Yaskawa-recommended
crimp terminals, tools, and insulation caps. Refer to the appropriate Wire Gauge and Torque
Specifications table for the wire gauge and screw size for your drive model. Place orders with
a Yaskawa representative or the Yaskawa sales department.
The closed-loop crimp terminal sizes and values listed in
recommendations. Refer to local codes for proper selections.

<1> Codes refer to a set of three crimp terminals and three insulation caps. Prepare input and output wiring using
two sets for each connection.
Example: Models with 14 AWG for both input and output require one set for input terminals and one set for
output terminals, so the user should order two sets of [100-066-218].
Note: Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the
voltage drop is greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal
block. Use the following formula to calculate the amount of voltage drop:
Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10

Factory Recommended Branch Circuit Protection
Yaskawa recommends installing one of the following types of branch circuit protection to
maintain compliance with UL508C. Semiconductor protective type fuses are preferred.
Alternate branch circuit protection devices are also listed in
Branch circuit protection shall be provided by any of the following:
• Non-time delay Class J, T, or CC fuses sized at 300% of the drive input rating
Note: The following model/fuse combinations are excluded from the preceding statement:
2A0002/A6T6, 2A0004/A6T15, 4A0004/A6T15, 4A0005/A6T20, and 4A0007/A6T25.
• Time delay Class J, T, or CC fuses sized at 175% of the drive input rating
• Time-delay Class RK5 fuses sized at 225% of the drive input rating
