2 Introduction

Thank you for your purchase of this QuietPower Inverter. As a high quality, true sine wave output
inverter, you can expect the QuietPower to deliver exceptional performance and give you years of
dependable operation. The true sine wave AC output from the QuietPower Inverter ensures all AC loads
operating from the unit perform efficiently and correctly. Since these loads were designed to operate from
true sine wave voltage, you can expect these loads to operate the same as if operating from grid/utility
supplied power. In some cases, the true sine wave output from the QuietPower Inverter is even superior
to the power supplied by your utility company.

To get the most out of your QuietPower Inverter, please carefully read and follow the instructions in this
guide. Pay special attention to the Important Safety Instructions in this guide and to the CAUTION and
WARNING statements found throughout the guide and on the product. Please retain all packaging.

2.1 QuietPower 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

· Totally silent: for quiet operation

· High surge capability: for ‘hard-to-start” AC loads

See Section 10 Specifications, for complete product specifications.

2.1.1. Inverter Function

When connected properly and the power switch is turned to the ‘|’ position, the QuietPower Inverter
draws power from a battery and delivers a true sine wave AC output voltage that is similar to the voltage
supplied by your local utility. As long as the battery voltage is 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).

2.1.2 Control Panel

The Control Panel provides ‘0/|’(Off/On) 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.

3 Installation

This section contains instructions for installing the QuietPower Inverter. After securing the unit and
making wiring connections, do not turn the unit on.

Proceed to the next section of the manual which provides operating instructions.

3.1 Requirements for Installation

What You Need to Install the QuietPower Inverter

You need the following tools and hardware to properly install the QuietPower Inverter:

· Wrench for DC terminals (½” or 13 mm)

· Wrench for Vibration Isolators (optional use)

· DC cables (supplied as PN 287A106)

3.2 Locating the QuietPower 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 0°C (32°F) and 25°C (77°F) - the cooler the
better within this range. Refer to the operating temperature information in the specifications section
of this manual.

· Ventilated: allow at least 5 inches (13 cm) of clearance all around the unit. Ensure that the ventilation
openings on the unit are not obstructed. If mounting in a compartment, ventilate with louvers or cut­outs.

· 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 either dust, wood
particles or other filings/shavings are present. These can be pulled into the unit when the cooling fan
is operating.

· Close to AC junction box: avoid the use of extended wire lengths if possible.

· 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 (see section

3.4.4). Also 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.

3.3 Mounting the QuietPower Inverter

Before mounting the QuietPower Inverter, test the chosen location for adequate space around the unit to
allow for connections and ventilation. Mounting hardware should be corrosion resistant and ¼” or 6 mm
diameter screws. Your mounting system should be able to support three times the weight of the
QuietPower Inverter, which weighs approximately 16 pounds (7.3Kg). The more clearance for ventilation
around the unit, the better the performance. At a minimum, have 5” of free space on all sides of the
inverter. For your convenience, four (4) Neoprene Cylindrical Sandwich Mount Vibration Isolators and
attachment hardware are provided for shock mounting.

To mount the QuietPower Inverter

Mount the QuietPower Inverter on either a horizontal or vertical surface (such as a bulkhead) using the
mounting holes provided. For secure, permanent mounting, use all eight mounting holes. Optionally, use
four shock mounts provided. To meet regulatory requirements, the QuietPower Inverter must be mounted
in one of the three orientations shown in Figure 1 below.

Remove and re-attach the front panel depending on
the orientation of the base unit itself. For example, if
the unit is mounted on a vertical surface, you may
want to remove the panel and attach it so it is again
readable horizontally. This can be done as depicted
in Figure 2, below, by removing the 4 screws, taking
the panel out of the housing, rotating the panel and
reattaching the panel to the base unit. Be sure to re­install all four screws.
