Introduction
The AIMS Power inverter 12,000 Watt inverter are the most advanced line of mobile DC to AC power
systems available. AIMS also offers the 8,000 Watt in 12V, or 10,000 Watt in 12V.
This model is used in a wide range of applications including back up power for remote
homes, off-grid systems, RVs, boats, commercial vehicles and mobile businesses. The
12,000 Watt inverter will operate most pumps, motors, lights, heaters and hand tools.
To get the most out of the power inverter, it must be installed and used properly. Read
the instructions in this manual before installing and using this model.

FUNCTIONS
FRONT VIEW
A. On/Off switch: Leave in the OFF position during installation.
B. Over temperature indicator: Lights when inverter protects itself against overheating. Inverter
shuts down while indicator is on. Inverter will restart automatically and indicator will turn off
when the inverter cools.
C. Over load indicator: Lights when inverter shuts down because of overload. Indicator will turn off
and inverter will restart when overload is removed.
D. Bar meters: Displays battery voltage and current. Current should be in the green zone for
continuous operation. The inverter will operate for several minutes when the current is in the
yellow zone. Operation with battery voltage or current in the red zone of a meter will result in
protective shutdown of inverter.
E. AC outlets: Maximum recommended output per outlet is 1500W.
F. Remote port: Used with remote switch to turn inverter ON/OFF (sold separately).
G. AC terminal block: Hard wire block providing inverter's full power.

A: Fan: Do not obstruct, allow at least l inch for air flow.
B: Battery terminals: Connect to 12V, or 24V, or 36V, or 48V (depending on inverter model) battery
(s) or other DC power source. "+" is positive & " - " is negative. Reverse polarity connection will blow
internal fuse and may damage inverter permanently. Make sure you check your input voltage and do
not REVERSE POLARITY! This will void the warranty.
C: Chassis ground lug: Connect to earth ground or to vehicle chassis using #8 AWG wire.
Warning! Operation of the inverter without a proper ground connection may result in an electrical
safety hazard.
QUICK HOOK-UP AND TESTING
If you would like to quickly hook-up the power inverter and check its performance before going ahead
with your installation, please follow these guidelines:
1. Unpack and inspect the power inverter, check to see that the power switch is in the OFF position.
2. Before you connect the battery cables, make sure the power switch is in the off position. Connect
Red (+) battery cable to Red (+) inverter terminal. Connect Black (-) battery cable to Black (-) inverter
terminal. Connect Red (+) battery cable to Red (+) battery terminal. Connect Black (-) battery cable to
Black (-) battery terminal. Alligator clamp cables may be used but only to connect to the battery. Do not
use clamps on inverter terminals. Alligator clamps are not a permanent solution. You may see a spark
during connection. Do not reverse the polarity. This may damage the inverter and void warranty.
Caution! Loosely tightened connectors result in excessive voltage drop and may cause overheated wires
and melted insulation. 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 our warranty.
Warning! You may observe a spark when you make this connection since current may flow to charge
capacitors in the power inverter. Do not make this connection in the presence of flammable fumes, as
explosion or fire may result.
3. Set the power switch to the on position. Check the meters and indicators on the front panel
of the inverter. The voltage bar graph should indicate 11 to 14 volts depending on the voltage
of the power source. If it does not, check your power source and the connections to inverter.

The other indicators should be off.
4. Set power inverter switch to the OFF position, the indicator lights may blink and the
internal alarm may sound momentarily. This is normal. Plug the test load into the AC
receptacle on the front panel of the inverter. Leave the test load switch off.
5. Set power inverter switch to the ON position and turn the testload on, the inverter should
supply power to the load. If youplan to measure the true output R.M.S. voltage of inverter, a
meter such as FLUKE 87A, BACKMAN 4410 or TRIPLETT 4200 must be used.
INSTALLATION
1. Where to install
The power inverter should be installed in a location that meets the following requirements:
a. Dry - Do not allow water to drip or splash onto the inverter.
b. Cool - Ambient air temperature should be between 0°C and 40°C, the cooler the better when
operating in this range
c. Ventilation - Allow at least one inch of clearance around the inverter for air flow. Ensure the
ventilation openings on the rear and bottom of the unit are not obstructed.
d. Safety - Do not install the inverter in the same compartment as batteries or in any compartment
capable of storing flammable liquids such as gasoline.
2. Cables
DC to AC inverters require high amperage/low voltage DC power to low amperage/high voltage AC
power. To operate properly, connect inverter DC input terminals direct to battery with heaviest wire
available see below:
24 Volt Model: 2 x set of 4/0 AWG (2 red + 2 black) and quantity 2- ANL500KIT-500 Amp fuse kits
Battery Cables Installation
When connecting the AC inverter to the battery terminals, it is important to connect the "+" wire to the
"+" terminal and the wire to the"-" wire to the “-“terminal. Do NOT reverse the polarity. It will void the
warranty. Make sure you connect negative to negative and positive to positive.
