Drive models with IP00 specifications become IP20/NEMA 1, UL Type 1 after correctly installing a top protective cover.
Do not attach the top protective cover when installing the drive in a control panel.
◆ Attaching the Top Protective Cover
Insert the small protruding hooks on the sides of the top protective cover into the provided mounting holes on the top of
the drive. Pinch the hooks inward so that the they connect with the mounting holes and fasten the top protective cover
back into place.
Note: Attaching the top protective cover and the bottom conduit bracket to an IP00 drive changes protection to IP20/NEMA 1, UL
Type 1.
