[. . . ] HG PI500 Operating Instructions for Your How Your HG PI500 Power Inverter Works 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. HighGear by Cobra 500 Watt Power Inverter Nothing comes close to a CobraTM A1 Controls and Indicators 1. 5. Thank you for purchasing the Cobra PI500 inverter. Properly used, this Cobra product will give you many years of reliable service. Customer Support MODIFIED SINE WAVE FAN DO NOT BLOCK 5 500 2. Should you encounter any problems with this product, or not understand its many features, please refer to this owner's manual. [. . . ] 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 form 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. Cables (included) Power wire and wiring is very important to the performance of the inverter. Because the inverter has a low voltage, high current input, low resistance wiring is essential between the battery and inverter. This is so it can deliver the maximum amount of energy to the load. Aluminum wire has about 1/3 more resistance than copper wire of the same size plus it is difficult to make good, lowresistance connections to aluminum wire. We recommend two #8 copper cables (90° C insulation rating) as the minimum size for connections between the battery and inverter. Keep the cable length as short as possible, no more than 4 ft. This will keep the voltage drop to a minimum. 8 9 Cables CAUTION: Electrical installations must meet local and national wiring codes, and should be performed by a qualified electrician. CAUTION: Do not connect the inverter and another AC source (such as a generator or utility power) to the AC wiring at the same time. CAUTION: Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and may permanently damage the unit. Such damage is not covered by the warranty. CAUTION: We recommend a main fuse in the battery's positive cable to protect against DC wiring short circuits (external to the inverter). The fuse should be as close to the battery as possible. We recommend a Buss Fuse ANL-250 or equivalent. The specific fuse ampere rating should be sized to allow operation of all your DC powered equipment. DC Wiring DC Wiring 1. Be sure the ON/OFF switch on the inverter is in the OFF position. MODIFIED SINE WAVE VENTS: DO NOT BLOCK Chassis CAUTION: REVERSED INPUT WILL BLOW FUSES FAN DO NOT BLOCK 5 500 2. Connect the cables to the power input terminals on the rear panel of the inverter. The red terminals are positive(+) and the black terminals are negative (-). Insert the bare ends of the cables into the terminals and tighten the screws to clamp the wires securely. 5. Connect the cable from the positive terminal of the inverter to the positive terminal of the battery's main fuse, or to 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. WARNING: Do not make this connection in the presence of flammable fumes. Thoroughly ventilate the battery compartment before making this connection. Operation. Turn the inverter On by using the ON/OFF switch on the left side panel .
