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 done
to keep the panel ambient temp within permissible range.

2.

This de-rating curve is based on inverter current rating when rated motor is connected.
