IP20/NEMA Type 1 Top Cover Removal and Installation
To improve the ambient temperature rating of a NEMA Type 1 drive from 40 °C to 50 °C or to mount NEMA Type 1
drives side-by-side, the top cover can be removed. Remove the top cover and set L8-35 to “2”.
Refer to Temperature Derating on page 327 for details.
Note: Removing the top cover of a
NEMA Type 1 drive converts the drive to an IP20/Open-Chassis rating, and the drive will no longer have
a NEMA Type 1 rating.
