Equipment Safety
WARNING!
Lethal Voltage
Review the system conguration to identify all possible sources
of energy. Ensure ALL sources of power are disconnected before
performing any installation or maintenance on this equipment.
Conrm that the terminals are de-energized using a validated
voltmeter (rated for a minimum 1000 VAC and 1000 VDC) to verify
the de-energized condition.
Do not perform any servicing other than that specied in the installation
instructions unless qualied to do so, or have been instructed to do so
by Go Power! Technical Support personnel.
To avoid electric shock, disconnect the DC input and AC input of
the inverter at least 5 minutes before performing any installation
or maintenance.
Do not tighten the AC and DC terminals or pull on the AC and DC wiring
when the inverter is running.
WARNING!
Fire Hazard
Do not keep combustible or ammable materials in the same room with
the equipment. Some products contain relays with moving parts and
are not ignition-protected.
Ensure AC, DC, and ground cable sizes conform to local codes. See
product manuals for minimum size requirements.
Ensure all conductors are in good condition.
Do not operate the unit with damaged or substandard cabling.
CAUTION!
Equipment Damage
When connecting cables from the inverter to the battery terminals,
ensure the proper polarity is observed. Connecting the cables
incorrectly can damage or destroy the equipment and void the
product warranty.
Thoroughly inspect the equipment prior to energizing. Verify that no
tools or equipment have been inadvertently left behind.
Keep all vents clear of obstructions that can prevent proper air ow
around, or through, the unit.

1. Do not install the Inverter into a building’s electrical system. The Inverter is a vehicu-
lar accessory. It is not designed to be safely used in a building’s electrical system and
has not been evaluated to meet building wiring codes. Improper application may
create a re or electric shock hazard.
2. To allow proper cooling, install in an indoor well-ventilated area and do not cover ventila-
tion openings or cooling fans. Do not install in engine compartment. Avoid placing the
Inverter on carpets and rugs; they are not only ammable, but they also obstruct
vents underneath the Inverter.
3. Keep combustible materials and gases away from the Inverter. The Inverter produces sparks
and heat during operation and could start a re.
4. Connect to a 12 VDC power supply only. A power supply with lower voltage will not oper-
ate the Inverter correctly, and higher voltage could damage the Inverter.
5. Connect input polarity properly. Incorrect connection will damage the Inverter and void
warranty.
6. Keep the Inverter dry and clean. Do not expose to rain, snow, spray, bilge water, or dust.
7. Use cables that are the appropriate size. The more power (amps) or the longer the cables,
the thicker they need to be to prevent overheating and re. See section 4.7 DC WIRING SIZE.
8. Install the Inverter as close to the DC source as possible, but not in a closed area with vent-
ed lead-acid batteries. Vented lead-acid batteries release explosive hydrogen gas that can
be ignited by the Inverter.
9. Mount the Inverter horizontally.
10. Verify that the installation surface has no hidden utility lines before drilling or driving
screws.
11. This product is not a toy. Keep it out of reach of children.
12. Do not use with positive ground electrical systems (most automobiles, trucks, and RVs have
negative ground systems).

4.2 INVERTER SHUTDOWN
The Inverter has a number of shutdown points, for the safety of the operator, the Inverter, and
the devices being used with it.
• If the DC input voltage drops too low, the alarm on the Inverter will sound. If the input
voltage drops further, the Inverter will shut down automatically to prevent permanent
battery damage. Recharge the battery as soon as possible.
• If the DC input voltage exceeds 16 VDC, the Inverter will shut down automatically.
• If the output load power rises higher than the rating power of the Inverter, the Inverter
may shut down automatically.
• The Inverter may automatically shut down if its internal temperature gets too high.
Note: even though this Inverter has built-in mechanisms to minimize damage, these situations
should be avoided because they can still damage the Inverter or battery.
4.3 WHERE TO INSTALL
Your Inverter should be installed in a location that meets the following requirements:
1. Dry: do not allow water to drip or splash on the Inverter.
2. Cool:ambient air temperature should be between 0°C and 40°C (the cooler the better).
3. Ventilated: allow at least two inches of clearance around the inverter for airow. Ensure
the ventilation openings on the rear and bottom of the unit are not obstructed.
4. Safe: do not install the Inverter in the same compartment as batteries or in any compart-
ment capable of igniting ammable liquids such as gasoline.
5. The Inverter should be located within 10 feet of the batteries.

4.5 INSTALLATION AND TESTING
Battery Type Selection:
•
Use only deep-cycle lead-acid batteries with this Inverter, such as 12 volt marine/RV
deep-cycle batteries. Do not use automotive, engine starting (SLI), or maintenance-free
wet cell batteries with this Inverter; they are designed for repeated, shallow discharge
and will wear out quickly.
•
Gel and AGM (Absorbed Glass Mat) batteries can be used with this Inverter, but they
require special charging procedures. Refer to battery supplier’s instructions.
1. Unpack and inspect the Inverter, and make sure the power switch is in the OFF position.
Note: we recommend using Go Power! DC Install Kits when installing a Go Power! Inverter
(sold separately). Check section 4.7 DC WIRING SIZE to determine what Install Kits works
for your Inverter.
2. Connect the DC Inverter cables into the power input terminals on the back of the Invert-
er. Remember, the (+) terminal is positive and the (-) terminal is negative. Place the lug
connector between the washers and tighten the terminal screw or nut to clamp the wires
securely. Ensure connections are tight.
3. Connect the ground cable to the appropriate location; see section 4.8 GROUNDING.
4. First, connect the DC Inverter cables from the negative terminal of the Inverter to the nega-
tive terminal of the battery. Make sure the connection is secure.
5. Before proceeding further, carefully check that the cable you just connected is going from
the negative terminal of the Inverter to the negative output terminal of the battery.
6. Install the Inverter fuse into the positive lead. The fuse should be located within 12” (31
cm) of the battery. Ensure all connections are tight and secure.
7. Connect the cable of the positive terminal of the Inverter to the positive terminal of the
battery. Make a secure connection. Check your polarity
CAUTION! Equipment Damage.
Loose connections result in excessive voltage drop and may cause
overheated wires and melted insulation. Ensure connections are tight.

CAUTION! Equipment Damage.
This Inverter cannot supply power to any AC distribution wiring or AC
loads in which the neutral and ground are connected (bonded). Doing
so will destroy the unit and void the warranty. If you do not understand
neutral to ground bonding, please have a professional install your
system for you. See section 4.8 GROUNDING for more information.
WARNING! Fire/explosion Hazard.
You may observe a spark when you make the nal battery connection
since current may ow to charge capacitors in the Inverter. Do not make
this connection in the presence of ammable fumes, as explosion or re
may result.
8. Set the power switch to the ON position. Check the meters and indicators on the front
panel of the Inverter. The Function LEDs should be green showing the Inverter is ON. If it
does not, check your battery bank and the connections to the Inverter. The other indicators
should be OFF.
9. Set the 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.
10. Set the Inverter switch to the ON position and turn the test load on; the Inverter should
supply power to the load. If you plan to measure the output voltage of the inverter, a true
RMS meter must be used for accurate readings.

4.6 BATTERY PRECAUTIONS
1. Wear splash-resistant ANSI-approved safety goggles and electrically-insulated gloves
while working near batteries.
2. Charge, store, and maintain batteries according to supplier’s instructions.
3. Locate batteries in a clean, well-ventilated area, away from ignition sources and ammable
materials. Vented lead-acid batteries release explosive hydrogen gas while charging.
4. Only connect similar batteries together. Do not connect old and new batteries together,
ooded and gel cells together, or batteries of different capacities together.
5. Only connect this Inverter to a 12V nominal battery bank. Do not attempt to connect
the Inverter to any other power source other than a battery with a nominal output
voltage of 12 volts or damage to the Inverter may occur and will void the warranty.
6. Connect batteries in parallel ONLY (negative terminals together to one cable; positive
terminals together to the other cable).
The following points must be observed for the DC Wiring.
•
The DC positive and negative cables connected to the Inverter from the battery bank
should be linked together with zip ties or electrical tape every 6”. This helps to reduce
radio frequency interference and reduces the effects of inductance both of which improve
the Inverter waveform and reduces the wear of the Inverters lter capacitors.
• To ensure optimum Inverter performance the number of connections between the battery
bank and the Inverter unit should be minimized except from the over-current and battery
disconnect devices. All additional connection points will cause extra voltage drops.
•
The Battery bank voltage must match the DC voltage required by the Inverter, which is 12V.
• All DC cable wire terminations should use a crimped and sealed copper ring terminal lugs.
• Make sure all cables have a smooth bend radius and no kinks are present.
• Colour code all DC Cables coming to/from the battery bank. Use coloured electrical tape
or heat shrink tubing. Red for positive (+), Black for negative (-) and Green for DC ground.

4.7 DC WIRING SIZING
The distance between the battery bank and the Inverter should be as short as possible to
achieve maximum efciency and to reduce re hazards. The gauge of the cable should be
sized appropriately to limit the voltage drop to less than 2% when carrying the maximum input
current to prevent frequent low-input voltage warnings and shutdown. Only use high quality
copper wire.
The cables should be as short as possible and the overall length of both cables added together
should be less than 10 ft (3 m) to comply with code requirements. Keeping your wire runs as
short as possible helps to prevent: low voltage shutdowns and nuisance tripping of the DC
breaker because of increased current draw. The table below shows the recommended DC cable
size, fuses/circuit breakers and DC grounding cable sizes for the Inverter (note: these values are
correct for cables in free air, not conduit).
