Temperature Derating
To ensure the maximum performance life, the drive output current must be derated as shown in Figure A.6 when the drive is
installed in areas with high ambient temperature or if drives are mounted in a cabinet. In order to ensure reliable drive overload
protection, set parameters L8-12 and L8-35 according to the installation conditions.
Note: To install a heatsink on the outside of a panel, design the panel to keep the air temperature inside the panel within 10 °C (5 °C for 2A0273
and 4A0124) of the outside air temperature.

IP00/Open-Chassis Enclosure
Drive operation between -10 °C and 50 °C allows 100% continuous current without derating.
IP20/NEMA Type 1 Enclosure
Drive operation between -10 °C and 40 °C allows 100% continuous current without derating. Operation between 40 °C and
50 °C requires output current derating.
Note: The temperature derating remains unchanged when removing the top protective cover and the bottom conduit bracket to change an IP20/
NEMA Type 1 enclosure drive to an IP00/Open-Type enclosure drive (derating required for temperatures over 40 °C).
External Heatsink Installation
Drive operation between -10 °C and 40 °C allows 100% continuous current without derating. Operation between 40 °C and
50 °C requires output current derating.
