Important Safety Instructions
WARNING
This chapter contains important safety and operating instructions. Read and keep this User Guide for future reference.
READ AND SAVE THESE INSTRUCTIONS
Before using the Xantrex CR Series Backup System Inverter ⁄ Charger (CR Series), read and obey all instructions and cautionary markings on the CR Series, the batteries, and in all sections of this instruction manual.
WARNING
The following warnings identify conditions or practices that could lead to injury or loss of life
1.To reduce risk of fire and electric shock, Xantrex recommends that all wiring be done by a qualified electrician to ensure adherence to the local and national electrical codes applicable in your application.
2.To reduce risk of injury and damage, charge only deepcycle lead acid type rechargeable batteries. Other types of batteries may burst, causing personal injury and damage.
3.To reduce risk of shock or fire, do not disassemble the CR Series. It contains no user-serviceable parts and internal capacitors remain charged after all power is disconnected. Take it to a qualified service center when service or repair is required. Incorrect re-assembly may result in risk of shock or fire.
4.To reduce risk of electric shock, disconnect all AC and DC sources before attempting any maintenance or cleaning. Turning off the CR Series will not reduce this risk.
iii
Safety
5.To reduce 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 CR Series with damaged or substandard wiring.
6.EXPLOSION HAZARD WORKING IN VICINITY OF A LEAD ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Provide ventilation to outdoors from the battery compartment. The battery enclosure should be designed to prevent accumulation and concentration of hydrogen gas in "pockets" at the top of the compartment. Vent the battery compartment from the highest point. A sloped lid can also be used to direct the flow to the vent opening location. Follow the instructions in this manual and those of the battery manufacturer regarding charging and ventilation.
7.EXPLOSION HAZARD: This equipment contains components which tend to produce arcs or can spark. To prevent fire or explosion, do not install the CR Series in compartments containing batteries or flammable materials or in locations that require ignition-protected equipment. This includes any space containing gasolinepowered machinery, fuel tanks, or joints, fittings, or other connections between components of the fuel system.
8.Do not operate the inverter/charger if it has received a sharp blow, been dropped, or otherwise damaged in any way. If the unit is damaged, see the Warranty information elsewhere in this manual.
9.To reduce risk of shock hazard and damage, do not expose the CR Series to rain, snow or liquids of any type. The CR Series is designed for indoor mounting only. Protect the CR Series from splashing if used in vehicle applications.
10.The inverter/charger must be properly grounded and provided with AC and DC disconnects and overcurrent protection as specified in this manual and in accordance with applicable electrical codes.
iv
Safety
11.Be extra cautious when working with metal tools on, or around batteries. The potential exists to drop a tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an explosion.
WARNING
Obey the following personal precautions while working with and charging batteries. These warnings concern conditions or practices that could lead to injury or loss of life.
1.Someone should be within range of your voice to come to your aid when you work near batteries.
2.Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3.Wear complete eye protection and clothing protection. Avoid touching eyes while working near batteries. Wash your hands when done.
4.If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eyes, immediately flood eyes with running cool water for at least 15 minutes and get medical attention immediately. Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the batteries
5.NEVER smoke or allow a spark or flame in vicinity of a battery or generator.
6.Be extra cautious when working with metal tools on, and around batteries. Potential exists to short-circuit the batteries or other electrical parts which may result in a spark which could cause an explosion.
7.Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery can produce a short-circuit current high enough to weld a ring, or the like, to metal causing severe burns.
v
Safety
CAUTION
The following cautions identify conditions or practices that could result in damage to the inverter/charger or other equipment
1.To reduce the risk of overheating, keep the ventilation openings clear and do not install the CR Series in a compartment with limited airflow. Maintain adequate clearance around the sides of the unit. Refer to the installation instructions in this manual.
2.Never charge a frozen battery.

1Introduction
CR Series Function and Operation
The following sections describe important aspects of the Xantrex CR Series Backup System Inverter ⁄ Charger (CR Series) operation. Read this to understand how the CR Series functions.
Inverter to Charger Transition
The internal battery charger and automatic transfer relay allow the unit to operate as either a battery charger or inverter (but not both at the same time). The CR Series automatically becomes a battery charger whenever AC power is supplied to its AC input, while also passing the incoming AC power through to the loads on the CR Series' AC output (load) terminals.
Charger Terminology
Constant current stage During this stage of the charge cycle, the batteries are charged at a constant current, ensuring rapid replacement of most of the battery's charge.
Constant voltage stage During this stage of the charge cycle, the batteries are held at a constant voltage and accept whatever current is required to maintain this voltage. This stage ensures replacement of the remaining charge not replaced during the constant current stage, while preventing the batteries from being over-charged.
7
Introduction
Transfer Switching Speed
While the CR Series is not designed specifically to operate as an uninterruptible power supply system (UPS), its transfer time is normally fast enough to maintain the power for computers. The relay transfer time is a maximum of 20 milliseconds.
2 Stage Operation
The CR Series is a simple 2 stage charger which holds the voltage steady (float) after charging. Both the charging and float voltage are 13.5 VDC (for 12 V models) and 27 VDC (for 24 V models).
CAUTION
To avoid damage to your batteries, ensure that your batteries are rated to withstand the constant float voltage.
