Closed-Loop Crimp Terminal Recommendations

Yaskawa recommends crimp terminals made by JST and Tokyo DIP for the insulation cap.

Table C.10

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

Table C.10

are Yaskawa

recommendations. Refer to local codes for proper selections.

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.
Branch circuit protection shall be provided by any of the following according to

Table C.11

.

• Non-time Delay Class J, T, or CC fuses.
• Time Delay Class J, T, CC, or RK5 fuses.
• Semiconductor fuses.
• Molded Case Circuit Breakers (MCCB).
