2.2 Mounting the Inverter
The inverter base can reach a temperature up to 90°C (194°F), and it is recommended that it 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 MS Series must be mounted in one of the following positions; as shown in
fi
gure 2-2:
above or under a horizontal surface (shelf or table),
or on a vertical surface (wall) with the DC terminals to the right.
CAUTION:
If the inverter is mounted in a way that the DC terminal ventilation openings
are oriented on the bottom, the ME-CB enclosure must be used. This enclosure prevents
burning material from falling out the bottom and also allows suf
fi
cient ventilation to
prevent the inverter from overheating under normal operating conditions.
After determining the mounting position, refer to the physical dimensions as shown in
fi
gure 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 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.
