INTRODUCTION The Xantrex Digital echo-charge is specially developed for charging an auxiliary battery with FreedomTM or Fleet Power® Inverter/Chargers or with any charging source. The Digital echo-charge automatically switches ON and OFF, charging a starter or auxiliary battery without affecting the main house battery bank. The maximum charge current is 15 amps when the starting battery is 1/2 volt to 1 volt DC less than the house battery.
THINGS YOU SHOULD KNOW Use only deep-cycle batteries in your house battery bank. Only similar batteries should be connected together in one bank. Do not connect old and new batteries together or wet and gel cell batteries together. Always use properly sized terminals and cables for your interconnecting battery cables. Starter battery and house battery banks should not be mixed in the same bank.
BEFORE YOU BEGIN The Digital echo-charge should be unpacked immediately upon receipt, and inspected to determine if any shipping damage has occurred. No special handling is necessary; however, care should be used to avoid dropping the unit or exposing it to dust and moisture.
INSTALLATION PRECAUTIONS Caution: To reduce the risk of electric shock and prevent premature failure from corrosion, do not mount where exposed to rain, drip or spray. Caution: Risk of electrical shock. Do not remove cover. No user serviceable parts inside. Refer service to qualified service personnel at a factory authorized service center or at the factory. Caution: Always wear safety glasses for eye protection when working with batteries.
INSTALLATION WARNING Make sure all charging sources are switched OFF and no charging voltage is present before beginning installation. Prevent unnecessary damage by carefully following the installation instructions. Battery Connections Two feet of 16 gauge wire with a ring terminal on the end is connected to the Digital echo-charge unit. Connect the ring terminals to the batteries as indicated. Connect from the echo-charge: • Ground wire (black) to the negative battery ground.
INSTALLATION WARNING Never disconnect battery cables while the charger is in operation.
OPERATION When the input voltage is 13.0/25.5 volts DC or higher, echo-charge automatically switches ON. The LED glows a steady green. When the input voltage is lower than 13.0/25.5 volts, the echo-charge automatically switches OFF, and the LED blinks green. The output voltage of echocharge is limited to 14.4/28.8 volts. When it reaches 14.4/28.8 volts, the charge current will decrease, maintaining a float condition. The starter battery will be fully charged without overcharging.
OPERATION It is important to install the Digital echo-charge in a well-ventilated location. An elevated temperature may cause the Operation LED to glow red and turn the echo-charge OFF. When the temperature cools down, the LED will return to green and the Digital echo-charge will resume normal operation.
TROUBLESHOOTING PROBLEM LED is red. Thermal shutdown THINGS TO CHECK 1. Check to see that the Digital echo-charge has sufficient air flow and ventilation around it. 2. Check the battery connections. 1. Check the difference in voltage between the house battery and the starter battery. If the difference is greater than 2 volts, the Digital echo-charge will reduce the charge current.
GLOSSARY AGM (Absorbed Glass Mat) Battery A lead acid, maintenance-free battery. Ah Capacity The ability of a fully charged battery to deliver a specified quantity of electricity (Amp-Hr., Ah) at a given rate (Amp, A) over a definite period of time (Hr.).
GLOSSARY Gel Cell Battery A type of battery that uses a gelled electrolyte solution. These batteries are sealed and are virtually maintenance-free. Not all sealed batteries are the gel cell type. Ground The reference potential of a circuit. In automotive use, the result of attaching one battery cable to the body or frame which is used as a path for completing a circuit in lieu of a direct wire from a component. This method is not suitable for connecting the negative cable of the inverter to ground.
