Locating and Mounting the inverter
Warnings:
• Do not mount the inverter near any flammable or combus-
tible fluid or components.
• Provide adequate clearance and ventilation to the inverter
• Mount the inverter only on a “noncombustible” surface.
• Maximum ambient temperature around the inverter must
not exceed 77° F (25° C) to meet power specifications.
The inverter should only be installed in a location that meets the
following requirements:
Clean and Dry - The inverter should not be installed in an area that
allows
dust, fumes, insects or rodents to enter or block the inverter’s
ventilation openings. This area also must be free from any risk of
condensation, water
or any other liquid that can enter or fall on the
inverter. The inverter uses stainless steel fasteners, plated copper
buss-bars, a power-coated aluminum base and the internal circuit
boards are conformal coated all done to help fight the harmful effects
of corrosive environments. However, the life of the inverter is
uncertain if used in these type of environments, and inverter failure
under these conditions is not covered under warranty.
Cool - The inverter should be
protected from direct exposure to the
sun or equipment that produces extreme heat.
The ambient air
temperature should be between 32° F (0° C) and 104° F (40° C);
realize that the inverters output specifications are rated at 77° F (25°
C), so the cooler the better within this range.
Ventilated - In order for the inverter to provide full output power and
avoid overtemperature fault conditions; do not cover or block the
inverters ventilation openings or install this inverter in an area with
limited airflow. Allow as much clearance around the inverters intake
and exhaust ventilation openings as possible, see items 12 and 13 in
figure 3. At the minimum, an airspace clearance of 6” (15 cm) at the
front and back and 3” (7.5 cm) everywhere else to provide adequate
ventilation.
If installed in an enclosure, a fresh air intake opening must be pro-
vided directly to the front side (intake vent) and an exhaust opening
on the back side (exhaust vent) of the inverter. This will allow cool air
from the outside to flow into the inverter and heated air to exit from
the inverter and out of the enclosure. When mounted in an enclosed
compartment, airflow must be at least 59 cfm in order to maintain no
more than a 68° F (20° C) rise in compartment temperature. Minimum
clearances can be reduced if airflow is increased, but in no case should
clearance around inverter be less than 2" (5 cm) on all sides.
Safe - Keep any flammable/combustible material (i.e. paper, cloth,
plastic, etc.) that may be ignited by heat, sparks or flames at a
minimum distance of 2 feet (60 cm) away from the inverter.
Do not install this inverter in any area that contains extremely
flammable liquids like gasoline or propane, or in locations that
require ignition-protected devices.
