Locating and Mounting the Inverter
WARNINGS:
• Do not mount the inverter near any fl ammable or
combustible 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. The 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);
keep in mind 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 inverter’s 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 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 open-
ing 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 tem-
perature. 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.
