Introduction; Controls, Indicators And Connectors - Vector VEC043 Owner's Manual

1. INTRODUCTION

Your new Vector MAXX 750 SST inverter is one in a series of the most advanced
DC to AC inverters available. With proper care and appropriate usage, it will
give you years of dependable service in your car, truck, RV or boat.
The MAXX 750 SST supplies 750 watts of continuous power, with a 1500 watt
peak, in the form of three household-type outlets that are ready to deliver 110 volt
AC power whenever and wherever you need it! The heavy-duty inverter has
enough power to run most household or electronic appliances. It also comes
equipped with battery clips to handle higher amperage/load applications, such as
power tools, stereo amplifiers, vacuums, etc. Added safety features include automatic
shutdown and a low battery alarm to prevent damage to your battery.
This power inverter is configured with the latest Soft Start Technology (SST). Before
introduction of soft-start, high start-up currents from large inductive loads could
shut down the inverter. Soft start improves inverter operation. Three major features
incorporated in SST include: first, gradual voltage ramp-up during inverter start-up.
This eliminates failed cold starts under load. Second, output that momentarily dips in
voltage and quickly recovers to allow large motorized loads to start. This eliminates
almost all shutdowns from momentary overloads. Last, the inverter automatically
re-starts when an overload that causes inverter shutdown is removed. Previously,
manual reset was required.
This power inverter also incorporates a new cooling technology that directly benefits
our customers. The new design more efficiently cools the power transistors, and
combined with soft start, dramatically increases reliability and the life of the product.

2. CONTROLS, INDICATORS AND CONNECTORS

Figure 1 details the front panel of the inverter. The front panel provides two LED
indicators. A green LED shows proper operation when lit. The red LED shows inverter
shutdown from overload, over voltage or over temperature. Power is supplied through
two grounded standard North American outlets. Outlets accommodate either two or
three pin AC plugs. An ON/OFF switch turns the inverter circuitry ON and OFF. The
switch is used to force a reset of inverter circuits if it is switched OFF, then ON.
