Installation
2.2 Mounting the Inverter
The inverter base can reach a temperature up to 194°F (90°C) and should be mounted on a
noncombustible surface
*
. This surface and the mounting hardware must also be capable of
supporting at least twice the weight of the inverter. To meet regulatory requirements, the
MSH3012RV must be mounted in one of the following positions as shown in Figure 2-2:
• above or under a horizontal surface (shelf or table),
• on a vertical surface (wall) with the DC terminals to the right,
• on a vertical surface (wall) with the DC terminals toward the bottom, and either the ME-CB or
MPX-CB conduit box installed on the inverter’s bottom.
Info:
The ME-CB or MPX-CB conduit box prevents material from falling out the bottom
in the event of an internal
fi
re, and also allow suf
fi
cient ventilation to prevent the
inverter from overheating under normal operating conditions.
Info:
Magnum provides a metal backplate for mounting the inverter. This backplate
also allows you to mount the MPX-CB conduit box (PN: BP-S single plate).
After determining the mounting position, refer to the physical dimensions as shown in Figure
2-3, or use the base of the inverter as a template to mark your mounting screw locations. After
marking the mounting screw locations, mount the unit with appropriate mounting hardware.
* Noncombustible 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 surfaces that are largely comprised of inorganic materials such as stone, steel,
iron, brick, tile, concrete, slate, and glass. Avoid common building materials such as gypsum board
as well as any paint, wall coverings, or wood.
