Iris Technology makes available a vehicle mounting plate for use with the Expanded-Capacity
HMMWV Fleet or HMMWV (ECV) which have Air Conditioning installed (PN 287A125). This
plate allows for direct bolt-on attachment without vehicle modification. A DoD/USMC
Modification Instruction (MI) exists that details the instructions for mounting this plate for
HMMWV (ECV) installation. (MI 11460A-OI/1)
2.4 Locating the Inverter
The QuietPower Inverter utilizes complex electronic circuits and although design precautions
have been made for protection of these circuits, they can be susceptible to damage from use in
extreme environments. The QuietPower Inverter should only be installed in a location that
meets the following requirements:
Dry: do not allow water or other fluids to drip or splash on the QuietPower Inverter. Do
not mount the QuietPower Inverter in an area subject to splashing or dripping water or
bilge.
Cool: normal ambient air temperature should be between -20°C (-4° F) and +60° C
(+140° F) - the cooler the better within this range. Refer to the operating temperature
information in paragraph 3.7.3.
Ventilated: allow at least 5 inches (13 cm) of clearance around unit. Ensure the
ventilation openings on the unit are not obstructed. If mounting in a compartment,
ventilate with louvers or cut-outs.
