    Exercise caution when applying the RSi S4 AC drive on low-line conditions. For example, an RSi S4 Series VFD will operate properly on a 208VAC line - but the maximum output voltage will be limited to 208VAC. Now if a motor rated for 230VAC line voltage is controlled by this drive, higher motor currents and increased heating will result.
