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.

FIRE AND SHOCK HAZARD. MAKE SURE THE CABLE IS

DISCONNECTED FROM 24 VDC POWER SOURCE PRIOR TO INSTALLING

CABLE ONTO INVERTER TERMINALS. FAILURE TO DISCONNECT

CABLE FROM 24 VDC POWER SOURCE (NATO PLUG) FIRST MAY

RESULT IN FIRE, SEVERE ELECTRIC SHOCK, OR DEATH.

CAUTION

Make sure cable is connected properly: positive (+), red wire to left post

and negative (-), black wire to right post. Connecting cable improperly

may result in internal damage to inverter.

3. Install the NATO Cable to the inverter first and then to the 24 VDC power source.

Refer to paragraph 2.6, Wiring the Inverter, for more information.

4. Before turning the inverter on, refer to Section 3, Operation.

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.
