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 75qC (167qF) at an ambient temperature of 50qC (122qF).

Use the terminal crimp with an insulation sheath or with processing by the insulation tube.
Use the insulated wire of 75qC (167qF), 600 V, HIV-insulated. This selection assumes the inverter is
used in ambient temperature at 50qC (122qF).
Note 1) A box (
) in the above table replaces S or E depending on the enclosure.
