The Magnum Inverter Hood (MP-HOOD) prevents objects from falling inside the top vents of your Magnum inverter and causing damage. Normally, Magnum inverters are mounted horizontally without any vents facing the top or bottom. However, in installations where these inverters are mounted on a vertical surface (DC side down) - such as on a MMP or MP enclosure - the Magnum Inverter Hood must be mounted above the inverter to meet UL regulatory requirements.
Do not mount the hood to the inverter chassis itself. Instead, mount it against the wall. The mounting slots will accept up to a ¼" screw or bolt.
