The Fuji NEMA1-220G1-24 is a NEMA 1 enclosure kit specifically for the FRENIC MEGA-SERIES FRN150G1S-2U drive. This is the sheet-metal top and bottom cover kit that converts the open-chassis drive to a NEMA 1 finger-safe, drip-proof enclosure for panel-less mounting.
What the NEMA 1 rating means for fit
This kit is intended for indoor, dry locations where the drive is mounted outside a panel. If your installation sees washdown, condensation, or dust, you would step up to a NEMA 12 or 4X enclosure separately.
