Protecting Circuit Terminals

Insulation Caps or Sleeves

Use insulation caps or sleeves when wiring the module with crimp terminals. Take particular care to ensure that the wiring
does not touch nearby terminals or the surrounding case.

Wire Gauges and Tightening Torque

Use the tables in this section to select the appropriate wires and crimp terminals.

Note: 1. Wire gauge recommendations based on continuous current ratings using 75

°C 600 Vac vinyl-sheathed wire assuming ambient

temperature within 40

°C.

2. Wire gauge recommendations for models 4A0270 to 4A0630 based on continuous current ratings using 105

°C 600 Vac vinyl-sheathed

wire assuming ambient temperature within 40

°C.

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) =

× wire resistance (Ω/km) × wire length (m) × current (A) × 10
