The "fault" indicator of your CPI 150 will light whenever the unit detects excessively high or low input voltage, or begins to overheat. Cigarette Lighter Plug Airplane Plug power/fault indicator CAUTION NOTE: Make sure you unplug inverter from power source before you leave your vehicle. 5 5 OPERATING LIMITS INPUT VOLTAGE/AUTO SHUTDOWN Power Output AC Output: Your CPI 150 will deliver 150 watts continuously. It can deliver 180 watts for about 30 minutes, after which it must cool for about 15 minutes before it can resume operation at 150 watts. (NOTE: the wattage rating applies to resistive loads.) USB Output: 5 Volt continuous output. Input Voltage Your CPI 150 will operate from input voltage ranging from 10 to 15 volts. Optimum performance occurs when the voltage is between 12 and 14 volts. The inverter will automatically shut down if the input voltage drops below 10.0 ± 0.3 volts. This protects the battery from being overdischarged. The inverter will restart when the input voltage exceeds 12.0 ± 0.3 volts. The inverter will also shut down if the input voltage increases to 15.5 ± 0.5 volts. This helps protect the unit from damage due to excessive input voltage. Although the inverter is protected in this way, it may still be damaged should the input voltage exceed 16 volts. Automatic Shutdown The unit will automatically go into thermal shutdown if it becomes overheated due to excessive input voltage, poor circulation or high ambient temperature. 6
