Explosive Gas Precautions
This equipment contains components which can produce arcs or sparks. To
prevent fire or explosion do not install in compartments containing batteries or flammable
materials or in locations which require ignition protected equipment. This includes any
space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other
connection between components of the fuel system.
Working in the vicinity of a lead-acid battery is dangerous. Batteries generate
explosive gasses during normal battery operation.
To reduce the risk of battery explosion, follow these instructions and those
published by the battery manufacturer and the manufacturer of the equipment in
which the battery is installed.
Precautions When Working With Batteries
Do not work alone. Someone should be within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.
Wear complete eye protection and clothing protection. Avoid touching eyes while
working near batteries.
Wear eye protection to keep corrosion from coming in contact with eyes, when
cleaning battery terminals and before making connections.
If battery acid contacts skin or clothing, wash immediately with soap and water. If
acid enters eye, immediately flood eye with running cold water for at least 20 minutes
and get medical attention immediately.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
Do not drop a metal tool on the battery, nor allow metal to contact the battery
terminals or vehicle chassis. The resulting spark or short-circuit on the battery or other
electrical part may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches
when working with a lead-acid battery. A lead-acid battery produces a short-circuit
current high enough to weld a ring or the like to metal, causing a severe burn.

1.3 Inverter Key Features
The QuietPower Inverter utilizes advanced high frequency switching technology in the power
conversion process. The circuits are similar to those used in power supplies for computers and
other electronic equipment. This technology offers several benefits:
Light weight: for easy installation
Pure sine wave output: for reduced interference
High surge capability: for „hard-to-start” AC loads
High frequency switching: for nearly silent operation
Refer to paragraph 3.7, Performance Graphs and Specifications, for complete specifications.
1.3.1 Inverter Function
When connected properly and the power switch is turned to the „I‟ (On) position, the QuietPower
Inverter draws power from the 24 VDC (nominal) battery and/or vehicle electrical bus and
delivers a true sine wave 115 VAC (nominal @ 15 A) output. As long as the input voltage is
maintained within the operating range of the unit, the QuietPower will continue to deliver AC
power to the loads connected. High and low battery shutdowns will engage if the battery
voltage falls out of the specified range of operation (20-32 VDC).
1.3.2 Control Panel
The Control Panel provides Off/On („O/I‟) control and displays operating information so you can
monitor the status of the Inverter and your batteries.
This panel can be removed and re-attached in different orientations so the display information is
directed at you in the most convenient fashion for all recommended mounting configurations.
The procedure to rotate the panel is found in section 2.5.

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.

Safe: DO NOT install the QuietPower Inverter in the same compartment as batteries or
in any compartment capable of storing flammable liquids such as gasoline. DO NOT
install the QuietPower Inverter in an engine compartment or other location where ignition
protected equipment is required.
Dust-free: DO NOT install the QuietPower Inverter in a dusty environment where dust,
wood particles or other filings/shavings are present. These can be pulled into the unit
when the cooling fan is operating.
Avoid the use of AC extension cord(s) wherever possible.If extension cords must
be used, they must be three (3) conductor cords (grounded) and must be suitable for the
circuit current (20A).
Install QuietPower Inverter close to battery/batteries: avoid excessive cable lengths
but DO NOT install the QuietPower Inverter in the same compartment as batteries. Use
the recommended wire lengths and sizes (refer to paragraph 2.6, Wiring the Inverter).
DO NOT mount the QuietPower Inverter where it will be exposed to the gases produced
by the battery. These gases are very corrosive and prolonged exposure will damage the
QuietPower Inverter.
Protected from battery acid: Never allow battery acid to drip on the QuietPower
Inverter or its wiring when reading specific gravity or filling the battery.
