Introduction

Congratulations! You’ve purchased the most advanced, feature-rich integrated inverter/battery charger on the market. Your APS provides your equipment with utility-supplied AC power when it is available, and during blackouts, overvoltages and brownouts, your APS automatically switches over to an external battery source to power connected equipment with voltage and frequencycontrolled AC power. In addition to reliable APS performance, your model features:

• 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

Your APS provides an uninterruptible power supply. 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.

Advanced, 3-Stage Battery Charger

Your APS recharges your battery faster than conventional chargers because its three-stage charger profile (Bulk, Absorption and Float) are optimized, regardless of the type of battery you use (Wet or Gel).* In addition, the advanced charging system protects against over-charge and over-discharge to ensure a longer service life from your battery.

* The Absorption and Float levels vary according to

battery type, which can be set to either “Wet” or “Gel”cell.

• Voltage Regulation (Select models only)

“VR” APS models regulate incoming AC power by automatically “boosting” or “cutting” the voltage to keep your equipment running through brownouts and overvoltages

without draining battery

power

• Load Sharing (Select models only)

Select APS models can be set to limit their own charging functions so they can charge their batteries at the quickest rate possible without overloading their power input circuits.

• Frequency-Controlled Inverter Output

All APS models feature Frequency-Controlled Inverter Output which allows devices dependent on AC line frequency (such as computers, VCRs, CD players, tape recorders, clocks and turntables) to operate properly.

• Circuit Board Protection

A silicone conformal coating safeguards the circuit boards against moisture.

Safety

This manual contains important instructions and warnings that should be followed during the installation, operation and storage of all Tripp Lite APS Systems.

APS Location Warnings

• Install your APS indoors, away from excess moisture or heat, dust or direct sunlight.

• Your APS is NOT waterproof. Contact with water can cause the unit to short circuit and could cause personal injury due to electric shock. Never immerse your APS. Mount it in the driest location available.

• Leave adequate space around all sides of the APS for proper ventilation. The heavier the load of connected equipment, the more heat will be generated by the APS.

• Do not install the APS near magnetic storage media, as this may result in data corruption.

Battery Connection Warnings

• Your APS will not operate with or without utility power until batteries are connected.

• Multiple battery systems must be made up of batteries of the same voltage, age, amp hour capacity and type.

• Keep battery location well ventilated. Explosive hydrogen gas can accumulate near batteries if they are not kept well ventilated.

• Sparks may result during final battery connection. Always observe proper polarity as batteries are connected.

• Do not allow objects to contact the two DC input terminals. Do not short or bridge these terminals together. Serious injury to property or person could result.

Equipment Connection Warnings

• Do not use Tripp Lite APS Systems in life support applications where a malfunction or failure of a Tripp Lite APS System could cause failure or significantly alter the performance of a life support device.

• Do not connect a surge suppressor, line conditioner or UPS to the output of the APS.

• Corded models: Do not modify the APS's plug in a way that eliminates its ground connection. Do not use power adapters that will eliminate the plug's ground connection. Connect your APS only to a properly grounded AC power outlet. Do not plug your APS into itself; this will damage the APS and void your warranty.

Operation Warnings

• Your APS does not require routine maintenance. Do not open your APS for any reason. There are no user-serviceable parts inside.

• Potentially lethal voltages exist within this unit as long as the battery supply and/or AC input are connected. During any service work, the battery supply and AC input connection (if any) should therefore be disconnected.

• Do not connect or disconnect batteries while the APS is operating from the battery supply. Dangerous arcing may result.

BATTERY TYPE / VOLTAGE POINT

Using a small tool, set the 4 “Battery Type / Voltage Point” Configuration DIP Switches, Group A (located on the front panel of your APS; see Diagram 1, p. 32) to select battery type and set the voltage range outside of which your APS will switch to battery power.

• Select Battery Type

(DIP Switch #1, Group A)

CAUTION: The Battery Type DIP Switch setting must match the type of batteries you connect or your batteries may be degraded or damaged over an extended period of time. See “Battery Selection,” page 7 for more information.

• Select Low AC Voltage Switch To Battery Point

(DIP Switches #4, Group A & #3, Group A)

Most loads will perform adequately when your APS’s High AC Voltage Point DIP Switch #2 is set to 135V and its Low AC Voltage Point DIP Switches #3 and #4 are set to 95V. However, if your APS frequently switches to battery power due to momentary high/low line voltage swings that would have little effect on equipment operation, you may wish to adjust these settings. By raising the High AC Voltage Switch to Battery point and/or lowering the Low AC Voltage Switch to Battery Point, you may reduce the number of times your APS switches to battery due to voltage swings.

• Load Sharing

(DIP Switches #1, Group B & #2, Group B) Your APS features a high-output battery charger that can draw a significant amount of power

from your line power source when charging at its maximum rate. If an APS is supplying its full AC power rating to its connected load at the same time as it is charging, it could trip its line source circuit breaker.Tripping this breaker will cut off AC power to your load and stop battery charging.

To reduce the chance of tripping this breaker, select APS models may be set to automatically limit their charger output to keep the sum of their AC load and charger power within their circuit breakers’ rating.

This charger limiting function has four settings, allowing you to choose less charger limiting for APS configurations with higher rated breakers. The figures below show how to set your DIP Switches to select how heavy a load can be placed on your APS before charger limiting begins.

• Equalize Battery Charge

(DIP Switch #3, Group B) This DIP Switch is momentarily engaged to begin the process of equalizing the internal resistance

of your battery's cells. This can extend the useful life of certain types of batteries; consult with your battery's manufacturer to determine if your batteries could benefit from this process.The charge equalization process is automatic and once started can only be stopped by removing the input power.

SETTING PROCEDURE:

1) Move to “Equalize” (DOWN) position for three seconds.

2) Move to “Reset” (UP) position and leave it there.

CAUTION: Battery charge equalization should only be performed in strict accordance with the battery manufacturer's instructions and specifications.

CAUTION: Do not leave DIP switch #3 in the down position after beginning process.
