User manual COBRA CPI800

[. . . ] Introduction Our Thanks To You Thank you for purchasing the Cobra® CPI 800 inverter. Properly used, this Cobra® product will give you many years of reliable service. Operating Instructions How Your Cobra® Power Inverter Works The Cobra® Power Inverter is an electronic product that has been designed and built to take low voltage DC (Direct Current) power from your automobile or other low voltage power supplies and CONVERT it to standard 115 Volt AC (Alternating Current) power like the current you have in your home. This conversion process thereby allows you to use many of your household appliances and electronic products in automobiles, RVs, boats, tractors, trucks and virtually anywhere else.

[. . . ] Connect the cable from the Positive (Red) Terminal of the inverter to the Positive Terminal of the power source (the battery's main fuse or the battery selector switch, if you are using one). You might observe a spark when you make this connection since current can flow to charge capacitors in the inverter. All power connections to your Cobra® inverter must be Positive to Positive and Negative to Negative. Connect Power Source CAUTION Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and may permanently damage the unit. Be careful not to short circuit the battery with any metallic object (wrench, etc. ). Do not work on AC wiring when it is connected to the inverter (even if it is switched off) unless the DC power source is physically disconnected from the inverter. Also, do not work on AC wiring if it is connected to another AC power source such as a generator or the utility line. WARNING You may observe a spark when making the connection because current can flow to charge the capacitors in the inverter. Estimate the time (in hours) that each piece of equipment will be running between battery charging cycles. Calculate th total watt-hours of energy consumption (power x operating time) using the average power consumption and the total estimated running time (in hours). Power x Operating Time = Watt-Hours. Laptop TV/VCR (up to 25") Blender The inverter is now ready to deliver AC power to your loads. If several loads are to be operated by the inverter, turn them On separately, after the inverter has been turned On. This will ensure that the inverter does not have to deliver the starting currents required for all the loads at once. On the left side panel, switch the On/Off Switch to Off. On/Off Switch to Off 100 Watts x 2 hours = 200 Watt-Hours 115 Watts x 3 hours = 345 Watt-Hours 300 Watts x 15 min = 75 Watt-Hours NOTE The On/Off Switch turns the control circuit in the inverter On and Off. Divide the watt-hours by ten (10) to determine how many power supply's (12 volt) ampere-hours will be consumed. 10 English Continued. . . Nothing comes close to a CobraTM 11 Operation Power & Protection Indicators Operation Operating Limits · NOTE When the switch is in the Off position, the inverter draws no current from the battery. When it's in the 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 rate depending on the age of the battery. Power and Protection Indicators · The Power and Protection Indicators include a green light, a red light and an alarm. Red Light and/or Alarm Current Overload ­ The red light will turn On momentarily, then the inverter will shutdown. The inverter will continue to check for appropriate current levels while trying to restart the load. Voltage Overload ­ The red light will blink and the inverter will shutdown. The inverter will continue to check for appropriate voltage levels while trying to restart the load. Voltage Shortage ­ As a warning that the voltage is getting low, the internal alarm will sound.
