Introduction
Congratulations! You’ve purchased the most advanced, feature-rich integrated inverter/battery
charger on the market. Your APS powers connected equipment, switching manually or automat-
ically from utility power to power inverted from an external battery or batteries. In addition to
reliable APS performance, your model provides:
High Efficiency Output
Your APS’s advanced circuitry produces a more efficient DC-to-AC conversion, minimizing
energy loss. This allows you to run connected equipment longer between battery charges. The
APS will maintain this highly-efficient output even as the battery charge decreases.
Automatic Overload Protection
If you overload your APS, it will automatically protect itself and your valuable batteries from
damage.
Fast Load Switching
If AC power goes down, your APS will switch over to providing battery backup power in 6
milliseconds or less so that your equipment will operate with no interruption.
Multi-Function Indicator Lights
Several sets of multifunction indicator lights keep you constantly informed of battery charge
levels, fault conditions and APS operation.
Multi-Operation Switches
An array of user-configurable switches gives you convenient options when operating your
APS. You can select the voltage level at which your APS’s inverter will turn on to maximize
equipment protection and minimize battery drain; set your APS for maximum charging
efficiency with your battery type; even set up your APS for remote control operation.
