If the label on your tool's AC adapter or charger states that is produces a low voltage AC or DC output (less than 30 volts) you can safely power the charger with your CPI 150. In order to check the performance of your CPI 150 before installing it, please have the following on hand: 1. [. . . ] Insert the cigarette lighter plug into your vehicle's cigarette lighter. Plug the power cord from the test load into the inverter's AC receptacle. Turning on Your Power Inverter Turn on your CPI 150 by pushing the ON/OFF switch to ON. The unit is now ready to deliver AC power to your loads. ON/OFF switch AC Output POWER FAULT CAUTION To prevent fire, do not cover or obstruct ventilation openings. Overheating may result. OFF ON 3 4 4 CONTROLS & INDICATORS You don't have to worry about excessive drain on a battery if you leave the inverter switched on for a few days. However, you should switch it off if you are not planning to recharge the battery within about a week. OPERATING LIMITS INPUT VOLTAGE/AUTO SHUTDOWN 5 On/Off Switch The ON/OFF switch turns the control circuit in the inverter on and off. It DOES NOT disconnect power from the inverter. ON/OFF switch AC Output POWER FAULT Power 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. ) 10. 0 ± 0. 3 volts. The inverter will restart when the input voltage exceeds 12. 0 ± 0. 5 volts. The inverter will also shut down if the input voltage increases to 15. 0 ± 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. OFF ON Fault Indicator The "fault" indicator of your CPI 150 will light whenever the unit detects excessively high or low input voltage, or begins to overheat. When the switch is in the OFF position, the inverter draws no current from the battery. When it is the in ON position, but no power is being supplied to the load, the inverter draws less than 500 milliamperes from the battery. It would take more than a week to discharge a 100 ampere-hour battery at this draw rate. 5 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. If the voltage drops below 10. 7 ± 0. 3 volts, an audible low battery alarm will sound. The inverter will automatically shut down if the input voltage drops below fault indicator POWER FAULT 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 OFF ON 6 TROUBLESHOOTING GUIDE Possible Causes Solution MAINTENANCE & SERVICE Problem/ Symptom Maintaining Your Inverter Your CPI 150 requires very little maintenance to keep it operating properly. The exterior of the unit should be cleaned periodically with a damp cloth to prevent accumulation of dust and dirt. [. . . ] For each piece of equipment you will be powering with your CPI 150, you must determine the battery's capacity (how long the battery can deliver a specific amount of current). For example, automotive batteries usually provide 25 amperes of current. A battery with a reserve capacity of 180 minutes can deliver 25 amperes for 180 minutes before it is completely discharged.
