Drive models with IP00 specifications become NEMA Type 1 after correctly installing a top protective cover. Do not attach
the top protective cover when installing the drive in a control panel.

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 NEMA Type 1.
