Important Safety Instructions
WARNING
This chapter contains important safety and operating instructions. Read and keep this Owner’s Guide for future reference.
1.Before installing and using the Xantrex PRO Inverter (XM 1800 or XM 1000), read all instructions and cautionary markings on the inverter, the batteries, and all appropriate sections of this guide.
2.Do not expose the Xantrex PRO Inverter to rain, snow, or spray. To reduce risk of fire hazard, do not cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance compartment. Overheating may result.
3.Use only attachments recommended or sold by the manufacturer. Doing otherwise may result in a risk of fire, electric shock, or injury to persons.
4.To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that wire is not undersized. Do not operate the inverter with damaged or substandard wiring.
5.Do not operate the inverter if it has received a sharp blow, been dropped, or otherwise damaged in any way. If the inverter is damaged, see the Warranty section.
6.Do not disassemble the inverter. It contains no user-serviceable parts. See Warranty for instructions on obtaining service. Attempting to service the inverter yourself may result in a risk of electrical shock or fire. Internal capacitors remain charged after all power is disconnected.
7.To reduce the risk of electrical shock, disconnect both AC and DC power from the inverter before attempting any maintenance or cleaning or working on any circuits connected to the inverter. Turning off controls will not reduce this risk.
8.The inverter must be provided with an equipment-grounding conductor connected to the AC input ground.

Safety
WARNING: Risk of injury or loss of life
Do not use Xantrex PRO Inverter in connection with life support systems or other medical equipment or devices.
Explosive Gas Precautions
WARNING: Explosion hazard
1.Working in the vicinity of lead-acid batteries is dangerous. Batteries generate explosive gases during normal operation. Therefore, you must read this guide and follow the instructions exactly before installing or using your Xantrex PRO Inverter.
2.This equipment contains components that tend to produce arcs or sparks. To prevent fire or explosion, do not install the inverter 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.
3.To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.

Safety
Precautions When Working With Batteries
WARNING: Explosion or fire hazard
1.Follow all instructions published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.
2.Make sure the area around the battery is well ventilated.
3.Never smoke or allow a spark or flame near the engine or batteries.
4.Use caution to reduce the risk of dropping a metal tool on the battery. It could spark or short circuit the battery or other electrical parts and could cause an explosion.
5.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.
6.Have someone within range of your voice or close enough to come to your aid when you work near a lead-acid battery.
7.Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
8.Wear complete eye protection and clothing protection. Avoid touching your eyes while working near batteries.
9.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.
10.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.

Safety
Precautions for Using Rechargeable Appliances
CAUTION: Equipment damage
The output of the inverter is non-sinusoidal.
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 Xantrex PRO Inverter. Do not use the following with the inverter:
•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.
If you are unsure about using your rechargeable appliance with the inverter, contact the equipment manufacturer to determine the rechargeable appliance’s compatibility with the modified sinewave (nonsinusoidal) AC waveform.

1 Introduction
Congratulations on your purchase of the Xantrex PRO Inverter (XM 1800 or XM 1000). The XM 1800 has been designed to give you quality power, ease of use, and reliability.
Please take a few moments to read this chapter to familiarize yourself with the main performance features and protection features of the XM 1800.
Quality Power
The XM 1800 is a quality inverter designed for recreational vehicle (RV) electrical systems that have a battery charger or generator already installed.
•The XM 1800 provides up to 1800 watts (XM 1800) or up to 1000 watts (XM 1000) of continuous modified sine wave power from a battery bank. It is designed to handle loads such as 1000 watt (XM 1800) or 600 watt (XM 1000) microwaves, TVs, VCRs, and midsized power tools.
•The XM 1800’s high surge capability lets you handle many hard-to- start loads, including large TVs and small refrigerators.
•The built-in transfer switch automatically transfers between inverter power and incoming AC power (shore power) to ensure power is always available.
•A built-in 15 A supplementary circuit breaker protects the XM 1800 from overload conditions to the GFCI receptacles.
•The XM 1800’s low standby battery demand means you don’t have to worry about excessive drain on your battery if you leave the inverter on for a few days. When the XM 1800 is on but no power is being supplied to a load, the inverter draws, on average, less than 0.5 A (XM 1000) or less than 0.7 A (XM 1800) from the battery.
•The cooling fan in the XM 1800 is both load activated and thermally activated. The fan turns off automatically after the inverter has cooled or the load has decreased.
1–1
Introduction
Comprehensive Protection
The XM 1800 is equipped with numerous protection features to guarantee safe and trouble-free operation:
Low battery alarm Alerts you if the battery has become discharged to 11.0 V or lower.
Low battery voltage shutdown Shuts the XM 1800 down automatically if the battery voltage drops below 10.5 V. This feature protects the battery from being completely discharged.
High battery voltage shutdown Shuts the XM 1800 down automatically if the input voltage rises to 15.5 V or more.
Overload alarm Alerts you if the loads connected to the XM 1800 are close to the inverter’s operating limits.
Overload shutdown Shuts the XM 1800 down automatically if the loads connected to the inverter exceed the inverter’s operating limits or if a short circuit is detected in the circuitry connected to the inverter’s output.
Over-temperature alarm Alerts you if the XM 1800 is running hot and is approaching the over-temperature shutdown level.
Over temperature shutdown Shuts the XM 1800 down automatically if its internal temperature rises above an acceptable level.
These values and thresholds are set at the factory and cannot be adjusted.

3 Installation
Chapter 3 provides information on cables and fuses to help you plan for your installation, and provides procedures for installing the XM 1800.
Xantrex strongly recommends that you read the entire chapter before starting to install the XM 1800, so that you can plan an installation that is suited to your power needs.
Designing Your Installation
Before doing anything else, you need to determine how you are going to use your XM 1800, 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
•Calculate the DC and AC cable sizes
•Select the correct fuses or circuit breakers.
Study Figure 3-1, “DC Input Configuration for Normal Loads” on page 3–2 and Figure 3-2, “DC Input Configuration for Heavy Loads” on page 3–3 for an examples 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
Installation Codes
Governing installation codes vary depending on the location and type of installation. Electrical installations must meet local and national wiring codes and should be performed by a qualified electrician.
In residential applications, electrical codes do not allow permanent connection of AC distribution wiring to the inverter’s AC output receptacles. The receptacles are intended for temporary (as-needed) connection of cord connected loads only.
Calculating Battery Requirements
Battery type and battery size strongly affect the performance of the XM 1800. 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. Xantrex recommends that you purchase as much battery capacity as possible.
Consult Appendix B, “Battery Types” for a detailed explanation of how to determine the appropriate number and size of batteries for your needs.
CAUTION
The XM 1800 must only be connected to a 12 volt battery system. It will not operate if connected to a 6 volt battery, and will be damaged if connected to a battery of 16 volts or more.
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.
Consult Appendix C, “Alternators and Charging Systems” for information about choosing an effective charging system.

Choosing an Appropriate Location
WARNING: Explosion or fire hazard
The XM 1800 contains components that may produce arcs or sparks. To prevent fire or explosion, do not install the inverter in compartments containing batteries or flammable materials, or in locations that require Ignition-Protected equipment such as areas containing gasoline engines, tanks, or fuel-line fittings.
WARNING: Fire hazard
To reduce the risk of fire, do not cover or obstruct the ventilation openings. Do not install the XM 1800 in a zero-clearance compartment. Overheating may result.
The XM 1800 must only be installed in a location that is:
:
Dry |
Do not allow water or other liquids to drip or splash on it. |
Cool |
Ambient air temperature should be between 32 ºF and |
|
105 ºF (0 ºC and 40 ºC)—the cooler the better within this |
|
range. |
Ventilated |
Allow at least 3 inches (7.5 cm) of clearance around the |
|
inverter for air flow. Ensure that the ventilation openings on |
|
the DC end of the unit 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 |

|
power. Voltage drop in AC wires is of less critical |
|
importance because resistance in wire carrying AC current |
|
is less. AC wires are also less expensive. In general, longer |
|
AC wires are preferable to longer DC cables. |

Installation
Calculating Cable Sizes
To operate safely and effectively, the XM 1800 needs proper cables and fuses. Because the XM 1800 has low-voltage and high-current input, it is essential that you use low-resistance wiring between the battery and the inverter 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 (one way)
•Chassis ground cable from the grounding point to the chassis ground screw on the inverter’s DC panel.
See Figure 3-3 on page 3–12.
WARNING: Fire hazard
Never use a DC cable longer than 5 feet (1.5 meters). A cable longer than 5 feet (1.5 meters) can potentially generate enough heat to start a fire or result in poor inverter performance.
Calculating Size of DC Input Cables
Refer to Table 3-1 to plan the DC input cabling for your application:
•Use only cable rated for 90 °C
•Oil-resistant cable is recommended
•Keep all cables as short as possible, and ensure that each cable between the inverter and the battery is no longer than 5 feet (1.5 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, lowresistance connections to aluminum wire.
