The 2 foot cigarette lighter plug wire and the 2 foot direct-to-battery 12 gauge wire 3. A test load such as a lamp or other small appliance that can be plugged into the AC receptacle on the inverter CAUTION Certain rechargers for small nickel cadmium batteries can be damaged if connected to the CPI 300. [. . . ] Plug the power cord from the test load into the inverter's AC receptacle. Check to be sure all power connections are secure. POWER FAULT ON/OFF switch OFF ON CAUTION A reverse polarity connection (positive to negative) will blow the fuse in the inverter and may permanently damage the unit. CAUTION To prevent fire, do not cover or obstruct ventilation openings. The inverter must only be connected to batteries with a nominal output voltage of 12 volts. If the inverter does not appear to work properly, refer to the Troubleshooting Guide on page 7. The unit is now ready to deliver AC power to your loads. If several loads are to be powered by the inverter, turn them on separately AFTER the inverter has been turned on. This will ensure that the inverter will not have to deliver the start-up currents required for all loads at once. 4 4 CONTROLS & INDICATORS 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. AC Output AC Output POWER FAULT Power Output Your CPI 300 will deliver 300 watts continuously. It can deliver 360 watts for about 30 minutes, after which it must cool for about 15 minutes before it can resume operation at 300 watts. (NOTE: the wattage rating applies to resistive loads. ) Fault Indicator The "fault" indicator of your CPI 300 will light whenever the unit detects excessively high or low input voltage, or begins to overheat. AC Output AC Output POWER FAULT ON/OFF switch OFF ON 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. You don't have to worry about excessive drain on a battery if you leave the inverter 5 Input Voltage Your CPI 300 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 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. fault indicator 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. OFF ON 6 6 TROUBLESHOOTING GUIDE Possible Causes Overload Low input voltage Short circuit or wiring error Solution Reduce the load. Check regulation of charging system. MAINTENANCE & SERVICE Problem/ Symptom Low output voltage No output voltage Maintaining Your Inverter Your CPI 300 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. [. . . ] The unit is completely insulated in input and output for added safety. Cobra Electronics Corporation warrants that its Cobra® Power Inverter, and the component parts thereof, will be free of defects in material and workmanship for a period of two (2) years from the date of consumer purchase. This warranty may be enforced by the first consumer purchaser, provided that the product is utilized within the U. S. A. Cobra® will, without charge, repair or replace, at its option, a defective inverter upon delivery to the Cobra® Factory Service Department, accompanied by proof of the date of first consumer purchase, such as duplicated sales receipt. You must pay initial shipping charges required to ship the product for warranty service, but the return charges will be at Cobra's expense, if the product is repaired or replaced under warranty.
