2.3.3 Recommended
wire
sizes
Table 2.7 lists the recommended wire sizes. The recommended wire sizes for the main circuits are
examples of using HIV single wire (for 75
°
C) at an ambient temperature of 50
°
C.

Use the terminal crimp with an insulation sheath or with processing by the insulation tube.
Use the insulated wire of 75
°
C, 600 V, HIV-insulated. This selection assumes the inverter is used in
ambient temperature at 50
°
C.

The nominal applied motor rating of FRN4.0E1S-4E to be shipped to the EU is 4.0 kW.
Note:
A box (
) in the above table replaces A, C, E, J, or K depending on the shipping destination.
For three-phase 200 V class series of inverters, it replaces A, C, J, or K.
