Caution:
1) The above graph is applied when inverter is in use within the permissible ambient temp. If the
unit is installed in a panel, install it where heat dissipation is properly made to keep the panel
ambient temp within permissible range.
2) This derating curve is based on inverter rated current when the rated motor for the inverter is
connected.
