Wiring Requirements WARNING ELECTRICAL SHOCK AND FIRE HAZARD Make sure that wiring is in good condition and that wire is not undersized. Do not operate the solar charge controller with damaged or substandard wiring. Failure to follow these instructions can result in death, serious injury, or equipment damage WARNING ELECTRICAL SHOCK HAZARD Use a torque screwdriver to tighten the screw terminals on the charge controller to 10.6 lb-in (1.2 N-m) torque to ensure a proper connection.
NOTICE REVERSE POLARITY n n Ensure that the "+" and "–" poles on both the battery and PV are connected correctly. Check polarity at all terminals before making the final DC connection. Pos(+) (red) cable must connect to "+" pole; Neg (–) (black) cable must connect to "–" pole. Failure to follow these instructions can result in nonoperation of equipment.
Mounting Requirements WARNING ELECTRICAL SHOCK AND FIRE HAZARD Do not cover or obstruct ventilation openings and/or heat sink. Do not mount in a zero-clearance compartment. Overheating may result. Failure to follow these instructions can result in death, serious injury, or equipment damage The charge controller should only be installed in locations that meet the following requirements: 18 Dry Do not allow water or other fluids to drip or splash on the charge controller.
Basic Installation Steps WARNING HAZARD OF ELECTRIC SHOCK AND FIRE n User shall install a fuse that is 1.25 to 2 times the rated current of the controller on the positive battery side with a distance from the battery not greater than 150 mm. n Ensure that the "+" and "–" poles on both the battery and PV are connected properly. n Intended for indoor dry locations only. n Do not charge a frozen battery. n Minimum charge ambient for Li-ion batteries is 0 °C (32 °F).

4 TROUBLESHOOTING WARNING ELECTRICAL SHOCK HAZARD Do not disassemble the charge controller. It does not contain any user-serviceable parts. Attempting to service the unit yourself could result in an electrical shock or burn. Failure to follow these instructions can result in death, serious injury, or equipment damage. NOTE: To obtain service go to Contact Information on page 1.
Common Issues Problem Solution Over-voltage event Check if the battery voltage is exceeding the over voltage disconnect point and disconnect the PV. Battery is discharged Charge the battery as soon as possible. The charge controller will stop charging the battery Over-temperature above 65 °C. Charging will resume when the battery event temperature cools down to 55 °C below.
Maintenance NOTE: Perform these inspections at least two times per year. n Make sure the charge controller remains in a dry environment. n Clean up any accumulated dust or dirt on the unit. n Check all the wires and cables for insulation damaged. Repair or replace, if necessary. n Tighten all terminal connections to the correct torque values, if applicable. Inspect for loose or broken wire connections.
