C: February 2001BATTERY CABLE CONNECTIONSCables must have crimped (or preferably, soldered and crimped) copper compression lugs unlessaluminum mechanical lugs are used. Soldered connections alone are not acceptable. We suggest usinghigh quality, UL-listed Xantrex battery cables. These cables are available in a specific assortment of sizesfrom 1-½ to 10 feet, and in 2/0 or 4/0 AWG. They are color-coded and have pressure-crimped, sealed-ringterminals. Contact your Xantrex dealer to order. Figure 11, illustrates proper method to connect the batterycables to the SW Series Inverter/Charger.Figure 11, Battery to Inverter Cable ConnectionINSTALLATION PROCEDURE - BATTERY CABLESCAUTION: THIS INVERTER IS NOT REVERSE POLARITY PROTECTED. If the positiveterminal of the battery is connected to the negative terminal of the inverter and vice versa, theresult will be instantaneous failure of nearly every power transistor. This type of damage isobvious and requires an extensive rebuilding of the inverter at your own cost. It is not covered bythe warranty.Ensure that the inverter is off before connecting or disconnecting the battery cables and that allAC power is disconnected from the inverter’s inputs.Determine the correct size battery cable to use for your installation from Table 2, on page 22 and theproper size disconnect/fuse from Table 3, Battery Cable To Maximum Breaker/Fuse Size on page 23.Color-code the cables with colored tape or heat shrink tubing [the standard colors are red for positive (+)and black for negative (-)]. Always double-check the polarity with a voltmeter before making the batteryconnectionsInstall the over-current device (fuse or circuit breaker) between the inverter and battery - as close aspossible to the battery - in the ungrounded conductor [typically the positive (red) cable]. Connect a cablefrom the battery negative terminal to the negative (black) terminal on the inverter.Observe Battery Polarity! Place the battery cable ring terminals over the stud and directly against the inverter’sbattery terminals. Red is positive (+), Black is negative (-). Use a 1/2-inch wrench or socket to tighten the 5/16SAE nut to 10-15 foot/pounds. Do not place anything between the cable ring terminal and the flat metalpart of the terminal or overheating of the terminal may occur. DO NOT APPLY ANY TYPE OF ANTI-OXIDANT PASTE until after the battery cable wiring is tightened to 10–15 foot-pounds!Note: Connecting the battery cables to the inverter battery terminals may cause a brief spark or arc- usually accompanied by a "snapping" sound. This is normal - don’t let it scare you. It is simply theinternal capacitors of the inverter being charged.2/0 Copper Compression Lug 2/0 Aluminum Mechanical LugDo not place anythingbetween battery cable lugand terminal surface.Assemble exactly as shown.
