Locating and Mounting the Inverter
WARNINGS:
• Do not mount the inverter near any fl ammable or com-
bustible fl uid or components.
• Provide adequate clearance/ventilation to the inverter.
• Mount only on a “non-combustible” surface.
• Maximum ambient temperature around the inverter must
not exceed 77° F (25° C) to meet power specifi cations.
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
busbars, and a power-coated aluminum base. Also, the internal circuit
boards are conformal coated. The above measures are undertaken
to help fi ght the harmful effects of corrosive environments. However,
the life of the inverter is uncertain if used in any of these types 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 any equipment that produces extreme heat. The ambient air
temperature should be between 32° F (0° C) and 104° F (40° C);
realize that the inverter’s output specifi cations 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 over-temperature fault conditions; do not cover or block the
inverters ventilation openings, or install this inverter in an area with
limited airfl ow. Allow as much clearance around the inverter’s intake
and exhaust ventilation openings as possible, see Items 12 and 13 in
Figure 3. At the minimum, allow an airspace clearance of 6” (15 cm) at
the front and back, and 3” (7.5 cm) everywhere else to provide ad-
equate 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 fl ow into the inverter, and heated air to exit away
from the inverter and the enclosure. When mounted in an enclosed
compartment, airfl ow 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 airfl ow is increased, but in no case should
clearance around the inverter be less than 2” (5 cm) on all sides.
Safe - Keep any fl ammable/combustible material (e.g., paper, cloth,
plastic, etc.) that may be ignited by heat, sparks, or fl ames at a
minimum distance of 2 feet (60 cm) away from the inverter.
