IMPORTANT SAFETY INSTRUCTIONS To ensure reliable service, your power inverter must be installed and used properly. Please read the installation and operating instructions thoroughly prior to installation and use. Pay particular attention to the WARNING and CAUTION statements in this User’s Manual. The CAUTION statements advise against certain conditions and practices that may result in damage to your inverter.
Important Cable Information Substantial power loss and reduced battery operating time results from inverters installed with cables that are not able to supply full power. Symptoms of low battery power can result from cables that are either excessively long or an insufficient gauge. Marine installations are also subjected to vibration and stresses that exceed those of other mobile installations.

PRINCIPLE OF OPERATION The MAXX SST inverter converts 12 volt DC (direct current) from a vehicle battery or ™ other 12 volt DC power source to standard 120 volt AC (alternating current) household power. It converts power in two stages (see the diagram below). In the first stage, the inverter raises the 12 volt DC input to 145 volts DC.
APPLIANCE POWER CONSUMPTION MAXX SST inverters are ideal for powering: ™ • Lights • TVs and TV/DVD (VCR) combinations units • Radio receivers/transceivers and stereo systems • Computers and peripheral equipment • Refrigerator/freezers • Small microwave ovens • Household appliances •...

battery connections are tight and the battery (or batteries) is (are) fully-charged. If the connections are good and the battery is charged, but the voltage still drops below 11 volts, you may need to use a larger battery (or battery combination).

operating time at full load. To extend operating time in general, reduce the heavy appliance load to a minimum. Remember, you are operating on stored energy and probably under power loss conditions. Note: All operating time curves assume permanent installation with the appropriate DC input wire (See the “Specifications”...
DC input to existing wiring (which must be approved for marine use) at the appropriate gauge, cable and length (see the “Specifications” section, page 16). For cable lengths exceeding 6 feet from inverter to batteries, call Vector for additional installation information. The cable, fuse holder and fuse (not supplied) can be purchased at an electrical supply company.
A. Check all connections and tighten any that may be loose. B. Ensure that the source battery has adequate charge. C. If steps A and B do not correct the problem, contact Vector Technical Support, toll-free, at (866) 584-5504, for assistance.
12 volt DC power source. Vector inverters should be operated in horizontal position; if it is to be mounted on a wall, mount it horizontally so that indicators, switches, outlets and terminal blocks on the front panel are visible and accessible.
If, after following all of the above steps, the inverter does not perform properly, the source voltage may be too low or the cables may be too long (or the gauge too light). Having checked and, if necessary, corrected these conditions, contact Vector Technical Support, toll-free, at (866) 584-5504 for assistance if problems persist.
Notes on Using the Remote Control (sold separately) For ease of use, Vector offers (as a separate item) a Remote Control specifically designed for this line of MAXX SST inverters. The inverter ON/OFF Switch must be in the OFF position when connecting the Remote Control to the unit or the Remote Control will not operate.
TROUBLESHOOTING Common Audio/Visual Problems “Buzzing” sound in audio systems Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their speakers when operated from the Power Inverter. This occurs because the power supply in the electronic device does not adequately filter the modified sine wave produced by the inverter.
