1. Important Safety Instructions
WARNING!
Before using the Inverter, read and save the safety
instructions.
1-1. General Safety Precautions
1-1-1. Do not expose the Inverter to rain, snow, spray, bilge or dust.
To reduce risk of hazard, do not cover or obstruct the ventilation
openings. Do not install the Inverter in a zero-clearance compartment.
Overheating may result.
1-1-2. To avoid a risk of fire and electronic shock. Make sure that existing
wiring is ingood electrical condition; and that wire size is not
undersized.
Do not operate the Inverter with damaged or substandard Wiring.
1-1-3. 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.
1-2. Precautions When Working with Batteries
1-2-1. 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.
1-2-2. Never smoke or allow a spark or flame in vicinity of battery or engine.
1-2-3. Do not drop a metal tool on the battery. The resulting spark or
short-circuit on the battery of other electrical part may cause an
explosion.
1-2-4. 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.

3-4. Installation：
Where to install. The power inverter should be installed in a location that
Meets the following requirements：
3-4-1. Dry – Do not allow water to drip or splash on the inverter.
3-4-2. Cool – Ambient air temperature should be between 0℃and 40℃, the
cooler the better.
3-4-3. Safe – Do not install in a battery compartment or other areas where
flammable fumes may exist, such as fuel storage areas or engine
compartments.
3-4-4. Ventilated – Allow at least one inch of clearance around the inverter
for air flow. Ensure the ventilation openings on the rear and front
of the unit are not obstructed.
3-4-5. Dust – Do not install the Inverter in a dusty environments
where are dust, wood particles or other filings/shavings are present.
These dust can be pulled into the unit when the cooling fan is
operating.
3-4-6. Close to batteries – Avoid excessive cable lengths but do not install
the Inverter in the same compartment as batteries.
Use the recommended wire lengths and sizes (see section 3-4).
Also do not mount the Inverter where it will be exposed to the
gases produced by the battery.
These gases are very corrosive and prolonged exposure also will
damage the Inverter.
WARNING!
Shock Hazard. Before proceeding further, carefully
check that the Inverter is NOT connected to any
batteries, and that all wiring is disconnected from any
electrical sources. Do not connect the output terminals
of the Inverter to an incoming AC source.
12

3-5. Making DC Wiring Connections：
Follow this procedure to connect the battery cables to the DC input terminals
of the Inverter. Your cables should be as short as possible (Ideally,
less than 6 feet / 1.8 meters ) enough to handle the required current in
accordance with the electrical codes or regulations application. Cables are
not an adequate gauge (too narrow) or too long will decrease the inverter
performances such as poor surge capability and low input voltage warnings
frequently and shutdowns. UVP warning presents due to DC voltage drop
across the cables from the inverter to the batteries.
The longer or narrower the cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.
Following cable recommendations for the best performance of inverter.
(Apply both 120V and 230V versions )

WARNING!
Make sure all the DC connections are tight (torque
to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections
could result overheat in a potential hazard.
13

WARNING!
The installation of a fuse must be on positive cable.
Failure to place a fuse on “+” cables running between
the inverter and battery may cause damage to the
inverter and will void warranty.
Also, use only high quality copper wire and keep cable length short, a
maximum of 3 - 6 feet.

3-5-1. Unpack and inspect the power inverter to check its performance,
switch to OFF position.
3-5-2. Connect the cables to the power input terminals on the rear panel of
the inverter. The red terminal is positive (+) and black terminal is
negative (-). Insert the cables into the terminals and tighten screw to
clamp the wires securely.
CAUTION !
Reverse polarity connection will blow a fuse in inverter
and may permanently damage the inverter.
Damage caused by reverse polarity connection is not
covered by warranty.

3-6. AC Safety Grounding：
The AC output ground wire should go to the grounding point for your loads
( for example, a distribution panel ground bus ).
3-6-1. Neutral Grounding (GFCI’S)：
3-6-1-1. 120V models：The neutral conductor of the AC output circuit
of the Inverter is automatically connected to the safety
ground during inverter operation. In accordance with the
National Electrical Code requirements that separately derived
AC sources (such as inverter and generators) have their
neutral conductors tied to ground in the same way that the
neutral conductor from the utility is tied to ground at the AC
breaker panel. For models configured with a transfer relay,
while AC utility power is presenting and the Inverter is in
bypass mode, this connection (neutral of the Inverter’s AC
output to input safety ground) is not present so that the utility
neutral is only connected to ground at your breaker panel,
as required.
3-6-1-2. 230V models：There is no connection made inverter interior
between either the line or neutral conductor to the safety
ground.
WARNING!
Risk of electronic shock. Use only Pass and Seymour, type
2091-W or 2094-W, ground – fault circuit-interrupter
receptacles. Others may fail in operating the inverter when
connecting to the inverter’s equipment.
16

Ground Fault Circuit Interrupters (GFCI)：
Installations in Recreational Vehicles (for North American approvals) will
require GFCI protection of all branch circuit connected to the AC output of
the hardwire terminal equipped Inverter. In addition, electrical codes
require GFCI protection of certain receptacles in residential installations.
While the pure sine wave output of the Inverter is equivalent to the
waveform provided by utilities, compliance with UL standards requires us to
test and recommend specific GFCI.
AMV has tested the following GFCI – protected 20A receptacles and found
that they functioned properly when connected to the output of the Inverter.
3-7. Inverter Operation：
To operate the power inverter, turn the main switch ON. The power inverter
is now ready to deliver AC power to your loads. If there is several loads use,
turn them on separately after the inverter has been “ON” in order to prevent
the OVP present caused by the surge power.
3-7-1. Set the power switch to the “ON” position and the buzzer will send
out “Beep” sounds at the moment the inverter will do self-diagnosis,
then the LED’s indicators will also appear various colors.
Finally the buzzer will sound another “Beep” and the Input Level and
Status LED indicators will turn to “Green” color, the inverter starts
working successfully.
3-7-2. Set the power switch to the OFF position, the inverter stops and all
the lights that are On, go Off.
3-7-3. Set power inverter switch to the ON position and turn the test load
On. The inverter should supply power to the load. If you plan to
accurately measure the true output r.m.s. voltage of inverter, a meter
such ad FLUKE 45 BECKMAN 4410 or TRIPLETT 4200 must be
used.
