Installation
2.4 Mounting
To meet regulatory requirements, the MMP enclosure must be mounted on a vertical surface (on
a wall) in an upright position, as shown in Figure 2-4. The DC breaker will not operate properly
unless in the vertical position.
Note the height you want to locate the MMP enclosure, and ensure you can access any controls
and wiring terminals. Refer to the physical dimensions as shown in Figure 2-2, or use the base of
the MMP as a template to mark your mounting screw locations. After marking the mounting screw
locations,
fi
rmly secure the MMP/inverter to the solid vertical surface using appropriate mounting
hardware.
This surface and the mounting hardware must also be capable of supporting at least three times
the combined weight of all the components (i.e., MMP enclosure, inverter, and any other accessory
mounted). When considering the strength of the support surface, remember the MMP enclosure
weighs 22.5 lbs. (10.2 kg), and the Magnum inverter can weigh up to 60 lbs. (27.2 kg).
If installing a Magnum inverter on the MMP enclosure, the inverter base can reach a temperature
up to 194°F (90°C); it is recommended that it should be mounted on a non-combustible surface*.
To meet regulatory requirements with a Magnum inverter mounted vertically, the included inverter
hood (PN: MP-HOOD) must be installed on the top to prevent the risk of
fi
re from objects falling
into the inverter. See Figure A5-1 in Appendix A for more information on the inverter hood.
Info:
Magnum provides a steel backplate (PN: BP-MMP) that has a suitable surface and
the required support for mounting the MMP enclosure and Magnum inverter together.
For information and dimensions on this backplate, see Figure A6-1
in Appendix A.
Info:
If mounting the MMP enclosure to wood (without a Magnum inverter), use at least
a #10 gauge sheet metal or wood screw. For concrete or hollow walls use a minimum
1/4 inch bolt and anchor.
* Non-combustible surface – A surface made of material that will not ignite, burn, support combustion,
or release fl ammable vapors when subjected to fi re or heat as per the ASTM E136 standard. For the most
part, these are materials that are largely comprised of inorganic materials such as stone, steel, iron, brick,
tile concrete, slate, and glass. Common building materials such as gypsum board as well as any paint, wall
coverings, and certainly wood will not pass.
