11. Installation
11.1 Mounting & thermal considerations
With the preceding guidelines in mind, choose a suitable location to mount the
MPT-3024. The unit must be mounted vertically against a hard, flat surface (i.e.
drywall or plywood) for proper ventilation and cooling. This will also discourage
foreign matter from entering the controller through the vents on the front
panel. Make sure that the vents are unobstructed. At higher outputs and high
ambient temperatures, the metal enclosure of the MPT-3024 may become
warm. To prevent overheating and failure, the controller will shut down if the
internal heatsink temperature exceeds 85
o
C (185
o
F). Overheating and shut-
down may occur if the controller is installed in an enclosure, in direct sunlight,
or where the ambient temperature is above 40
o
C (104
o
F). It must be manually
powered down and restarted if overtemperature shutdown occurs.
!
The MPT-3024 is not designed for damp locations, nor is it to be
installed outdoors, in unventilated enclosures, inside a wall cavity, in direct
sunlight, or near a source of heat (stove, radiator, register, etc.). Any of
these situations may cause controller failure and will void the warranty.
Mounting the MPT-3024 in a cool, dry location will increase operating
efficiency and will extend the life of the unit.
F
Compliance with national and local electrical regulations is always
recommended to ensure proper installation and safe operation of the
MPT-3024.
!
Some components within the MPT-3024 are static sensitive and may
be damaged by static electricity that has accumulated in your body. Before
removing the front cover, briefly touch something grounded and avoid
touching any components on the MPT-3024’s circuit board.
Remove the four screws that secure the front cover from the MPT-3024 (Figure
11.1.1) and disconnect the ribbon cable that connects the panel to the main
circuit board (see Figure 11.1.2). Set the front panel aside and securely fasten
the MPT-3024 to your chosen mounting surface through the four holes on the
outside edge of the enclosure, using the four screws provided.
