This includes any space containing gasoline-powered machinery, fuel
tanks, as well as joints, fittings, or other connections between
components of the fuel system.
4. Make sure the area around the battery is well ventilated.
5. Never smoke or allow a spark or flame near the engine or batteries.
6. Use caution to reduce the risk or dropping a metal tool on the battery.
It could spark or short circuit the battery or other electrical parts and
could cause an explosion.
7. If you need to remove a battery, always remove the ground terminal
from the battery first. Make sure all accessories are off so you don’t
cause a spark.
WARNING: Explosion or fire hazard

Safety
975-0556-01-01 vii
This guide for use by qualified installers only.
8. Remove all metal items, like rings, bracelets, and watches when
working with lead-acid batteries. Lead-acid batteries produce a short
circuit current high enough to weld metal to skin, causing a severe
burn.
9. Have someone within range of your voice or close enough to come to
your aid when you work near a lead-acid battery.
10. Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
11. Wear complete eye protection and clothing protection. Avoid
touching your eyes while working near batteries.
12. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.
Precautions for Using Rechargeable Appliances
Most rechargeable battery-operated equipment uses a separate charger or
transformer that is plugged into an AC receptacle and produces a low
voltage charging output.
Some chargers for small rechargeable batteries can be damaged if
connected to the XPower Inverter 3000. Do not use the following with the
XPower Inverter 3000:
• Small battery-operated appliances like flashlights, razors, and night
lights that can be plugged directly into an AC receptacle to recharge.
• Some chargers for battery packs used in power hand tools. These
affected chargers display a warning label stating that dangerous
voltages are present at the battery terminals.

1Designing Your Installation
Before doing anything else, you need to determine how you are going to
use your inverter, and then design a power system that will give you
maximum performance. The more thorough your planning, the better
your power needs will be met. In particular, you will need to:
• Be aware of installation codes
• Calculate your battery requirements
• Choose an effective charging system
• Choose an appropriate location and mounting orientation
• Calculate the cable size for your inverter
• Select the correct fuses or circuit breakers
Study Figures “Configuration for Normal Loads” on page 1–2 and
“Configuration for Heavy Loads” on page 1–3 for an example of a setup
for normal or heavy loads in a vehicle. When you have decided upon your
configuration, then you can calculate battery requirements.

Installation Codes
Governing installation codes vary depending on the location and type of
installation. Electrical installations must meet local and/or national wiring
codes and should be performed by a qualified electrician.
An example of a national wiring code is the US National Electrical Code
(NEC, NFPA70) article 551 governing electrical installations in RVs. In
other geographical regions or for other applications, other codes will
apply. It is the installer's responsibility to identify and apply all
applicable codes.
Calculating Battery Requirements
Battery type and battery size strongly affect the performance of the
inverter. Therefore, you need to identify the type of loads your inverter
will be powering, and how much you will be using them between charges.
Once you know how much power you will be using, you can determine
how much battery capacity you need. We recommend that you purchase
as much battery capacity as possible.
For information on calculating battery capacity, go to www.xantrex.com,
click “Support”, choose the product “Xpower Inverters”, and click
“Battery Calculator” under Calculators & Problem Solvers.
CAUTION: Equipment damage
The inverter must only be connected to a 12 V battery system. It will not operate
if connected to a 6 V battery and will be damaged if connected to a 24 V battery.

975-0556-01-01 1–5
This guide for use by qualified installers only.
Choosing an Effective Charging System
The charging system must be appropriate for your particular installation.
A well-designed charging system will ensure that power is available when
you need it and that your batteries remain in top condition. Inadequate
charging will degrade system performance, and the wrong type of charger
will reduce battery life.
For information about choosing an effective battery charging system, go
to www.xantrex.com, click “Support”, choose the product “Xpower
Battery Chargers”, and click “Selecting the Right battery Charger” under
Tech Notes.
NOTE: If the main charging source will be the vehicle's alternator, then its
voltage and current ratings must be appropriate for the size and type of
battery that is selected.
Choosing an Appropriate Location and Mounting Orientation
WARNING: Fire or explosion hazard
The inverter contains components which tend to produce arcs or sparks. To
prevent fire or explosion, do not install the XPower Inverter 3000 in
compartments containing batteries or flammable materials, or in locations that
require ignition-protected equipment. This includes any space containing
gasoline-powered machinery, fuel tanks, as well as joints, fittings, or other
connections between components of the fuel system.
WARNING: Fire hazard
To reduce the risk of fire, do not cover or obstruct the ventilation openings. Do
not install the inverter in a zero-clearance compartment. Overheating may result.
WARNING: Shock hazard
Do not install the Inverter 3000 in a wet environment or in any other environment
where moisture can occur and enter the inverter enclosure through the ventilation
openings. This unit is not intended for marine applications.

1–6 975-0556-01-01
This guide for use by qualified installers only.
Appropriate
Location The inverter must only be installed in a location that is:
:
Dry Do not allow water or other liquids to drop or splash on it.
Cool Ambient air temperature should be between 0 and 40ºC
(32 and 105ºF)—the cooler the better within this range.
Ventilated Allow at least 3" (76 mm) of clearance around the inverter
for air flow. Ensure that the ventilation openings on each
end of the inverter are not obstructed.
Safe Do not install the inverter in the same compartment as
batteries or in any compartment capable of storing
flammable liquids like gasoline.
Close to
battery Do not use excessive DC cable lengths: they increase wire resistance which leads to voltage drop and heating.
Consequently, they reduce available power and run-time.
Longer AC wires are preferable to longer DC wires: voltage
drop is less of an issue and the cost is lower.
Protected
from battery
gases
Do not mount the inverter where it will be exposed to gases
produced by batteries. Battery gases are corrosive, and
prolonged exposure to battery gases will damage the
inverter.

975-0556-01-01 1–7

Mounting
Orientation The inverter must be oriented in one of the following ways:
• Horizontally on a vertical surface. (Do not mount with the fan
pointing up or down.)
• On a horizontal surface.
• Under a horizontal surface.

Selecting Cable Sizes
To operate safely and effectively, the XPower Inverter 3000 needs proper
cables and fuses. The XPower Inverter 3000 has low-voltage and high-
current input, so it is essential that you use low-resistance wiring between
the battery and the inverter. This means using the largest gauge and
shortest DC cables. The goal is to deliver the maximum amount of usable
energy to your load.
For safe and efficient operation, you will need to calculate cable sizes for
your:
• DC input cables from the battery to inverter, and
• Chassis ground cable from the vehicle chassis to the chassis ground
lug on the inverter’s DC panel.
DC Input Cables
• Keep all cables as short as possible, and ensure that each cable
between the inverter and the battery is no longer than 10 feet (3 m).
• Do not use aluminum cable. It has about 1/3 more resistance than
copper cable of the same size, and it is difficult to make good, low-
resistance connections to aluminum wire.
• Some installation codes require and we recommend use of oil-
resistant cable rated for damp or wet locations.
• For installations subject to the US NEC, the minimum cable size
required is No. 4/0 AWG 75 °C1, with a maximum fuse size of
400 Adc.
• For other installations, other codes may apply, but in no case should
you use DC cables smaller than No. 2/0 AWG, protected by a
250 Adc fuse, but note that the five-minute 3000 W rating requires a
350 Adc fuse, which will require a minimum No. 4/0 AWG cable.
WARNING: Fire hazard
Use only copper wire rated 75 °C minimum. Never use a DC input cable longer
than specified in “DC Input Cables” below. A longer cable can potentially
generate enough heat to start a fire or result in poor inverter performance.
1.Based on US NEC, 2008, table 310-17, 75C copper wire.

975-0556-01-01 1–9
This guide for use by qualified installers only.
Selecting a DC Input Fuse or Circuit Breaker
The DC cables from the battery to the inverter need to be provided with
overcurrent protection, in the form of a fuse or circuit breaker, located as
close as possible to the DC positive battery terminal.
Because your batteries can provide thousands of amps of short-circuit
current, you need a DC-rated fuse or circuit breaker that can safely
interrupt the short-circuit current that the batteries can produce.
DCDisconnects
and Over-
Current Devices
The DC circuit from the battery to the inverter must be equipped with a
disconnect and over-current device. This usually consists of a circuit
breaker, a “fused-disconnect,” or a separate fuse and DC disconnect. Do
not confuse AC circuit breakers or fuses with DC-rated ones. They are not
interchangeable. The rating of the fuse or breaker must be matched to the
size of cables used in accordance with the applicable installation codes.
The breaker or disconnect switch and fuse should be located as close as
possible to the battery, in the positive cable. Applicable codes may limit
how far the protection can be from the battery.
To select the correct fuse type and size:
1. Determine the total short-circuit current rating for each battery, based
on the battery manufacturer's published short-circuit current sourcing
ratings for the battery. Then determine the total for your battery bank.
For example:
• If you are using one battery to power your inverter and its short-
circuit current rating is 500 A, the total short-circuit current rating
is 500 A.
• If you are powering your inverter with two 12 V batteries
connected in parallel, and each battery has a short-circuit current
rating of 500 A, the total short-circuit current rating is 1000 A.
• If you are powering your inverter with two 6 V batteries
connected in series, and each battery has a short-circuit current
rating of 500 A, the total short-circuit current rating is 500 A.
Important: For batteries connected in parallel, the total short-circuit current
rating is the sum of the short-circuit current ratings of all of the batteries
connected in parallel. For batteries connected in series, the total short-circuit
current rating is equal to the short-circuit rating of the battery with the highest
short-circuit rating. It is not the sum of all the short-circuit current ratings taken
from each connected battery.

1–10 975-0556-01-01
This guide for use by qualified installers only.
2. Once you have determined the total short-circuit current rating of
your batteries, select a fuse or circuit breaker that has:
• a short-circuit interrupting capacity at least equal to the total
short-circuit current rating of your battery bank, and
• a DC voltage rating of at least 16Vdc, and
• a current rating no more than the values given above.
3. If a fuse is used rather than a circuit breaker, a disconnect switch
located between the battery and the fuse is recommended, to allow the
circuit to be de-energized when replacing the fuse.
Fuses and circuit breakers can be bought at any RV supply store or
electrical products store.
Chassis Ground Wire Sizing
Connect a minimum No. 8 AWG1copper wire from the vehicle chassis to
the chassis ground terminal on the inverter DC panel.
Output Conductor Selection for Hardwire Installation
The inverter may be used by connecting cord-connected loads to the
receptacles on the front panel, and/or by connecting loads or a load circuit
to the AC output hardwire terminal block. If making connections to the
AC output hardwire terminal block, use jacketed No. 10 AWG2copper 2-
wire plus ground cable. Conductors may be solid or stranded.
Some installation codes require and we recommend use of oil-resistant
cable rated for damp or wet locations.
Color code for conductors:
Black = [L]ine (hot)
White = [N]eutral
Bare or green = [G]round
1.Based on US NEC 2008 article 551-20(c). Other codes may require larger
chassis ground cable, in some cases as large as the DC power cables.
2.Based on US NEC 2008, table 310-16, 75C copper wire.
