6Read the following applications and comply with them, and yourMAXXSST™ 3000 will give you years of reliable service.Never connect the inverter’s AC output to an already powered AC distribution system.If you will only be operating the MAXXSST™ inverter occasionally and manually,using the two outlets on the front panel of the inverter, then you can disregard thenext two sections (2.1 and 2.2), except for battery charging requirements.Two primary ways for connecting to an AC distribution system are provided insections 2.1 and 2.2.2.1 Uninterruptible Power Supply (UPS)One way is to continuously operate the inverter from the battery bank, simultaneouslyreplacing the charge on the battery bank using an AC-powered 12 Volt batterycharger or other means of charging the batteries, such as a solar charger system. SeeFIGURE 3. The charger must be selected to operate continuously and to be able toreplace the charge on the battery as the inverter operates. In this configuration, thebattery “floats” on the DC from the charger, not really supplying power or beingcharged. When outside AC fails, the inverter continues to power the appliancesfor the life of the useful charge on the battery bank. When outside AC is restored,the batteries are recharged as the inverter continues to operate. Battery rechargingmust be sized to replace the average daily current supplied by the inverter plus alittle more current. Another requirement is that the battery charging rate cannotexceed 10% of the rated Ampere Hour (AH) rating of the battery bank, otherwisethe life of the batteries can be dramatically reduced through overcharging. Mostmodern battery chargers automatically adjust the charging rate based on the stateof the batteries to which they are connected. For this type of operation, use deepcycle batteries and avoid charging at too fast a rate.215.5. Permanent Installation5.5.1 Preparation for Permanent InstallationNote than a prepared heavy duty 6 ft. cable kit can be purchased fromyour dealer or Vector Manufacturing. Call Tech Support at:(954) 584-4446 or (866) 584-5504 Ext. 19 ask for VEC085 cable set.For permanent installation to heavy-duty battery power you will need:• Ring terminals to connect two 0000 (4/0) cables to the battery bank• A single length of not more than ten feet of 0000 (4/0) multi-stranded flexibleinsulated cable• A 500 ampere low voltage fuse and fuse holder type ANL• Mounting screws, bolts and nuts for mounting the inverter and the fuse holder• Tools to drill holes for mounting the inverter and fuse holder• Lead-tin solder, flux, propane torch and an igniter for the torch• Sharp utility knife to cut insulation• Hacksaw to cut the 0000 (4/0) cable• Pair of diagonal cutters to trim away some cable strands if necessary• Ring terminals connector for 0000 4/0 cable for connection to battery(batteries)Installation Notes:The MAXXSST™ 3000 has four slots in its mounting bracket that allow the unitto be fastened against a bulkhead, floor, wall or other flat surface. Ideally, themounting surface should be cool to the touch. It is more electrically efficient to uselonger AC wiring than DC wiring, so install the inverter as close as possible to the12 VDC power source.The inverter can be operated in any position, however, if it is to be mounted on awall mount it horizontally so that indicators, switches, outlets and terminal blockslocated on the front panel are visible and accessible. Look for a convenient placeto mount inverter and the fuse holder. Take the length of cable and do a trial rout-ing of the cable. Don’t do any cutting at this time. Take a look at FIGURE 8.Measure the cable path and ensure that either the positive cable run to the batteryor negative cable run to the battery does not exceed 4 feet. Reposition theinverter and fuse holder if necessary. Remember and observe the otherenvironmental requirements described earlier.After you have selected an appropriate location for the inverter and fuse block,proceed with the actual installation of the inverter.Contact Vector™ for any further installation information or questions. Your can purchasefuses, fuse holders, and 4/0 cable or cable battery connectors from your localelectrical supplier or from Vector Technical Support at (954) 584-4446 Ext. 19.5.5.2 Permanent Installation ProceduresThe cables between the power source and the inverter should be as shown inFIGURE 8. Be sure to remove the carriage bolts before starting permanent installation.Inverter DC cables and fuse installation is as follows:
