1. INTRODUCTION

1.1 The Alpha CFR

Congratulations on your purchase of one of the most advanced and intelligent Controlled Ferro Resonant-Uninterruptible Power Supply (CFRUPS) in the world! The Alpha CFR is designed to keep your equipment operating, regardless of the condition of your utility power. This means that your vital equipment will no longer be affected by spikes, surges, sags, noise, brownouts, blackouts or other forms of electrical disturbances. Operation is as simple as plugging your equipment into the back of the UPS and switching on the power.

The CFR provides you with a wide range of power management options using your choice of interface devices. The Standard Interface Device displays vital UPS operating parameters, including Alarms, and allows you to manually self-test the UPS. The Intelligent Interface Device provides you with precise Voltage, Current and Frequency information, plus maintains an ongoing record of all Alarm and Line Failure Events. As an active center of communication, your CFR can also be interfaced directly to your computer system to inform you, and your users, of changes in status as they occur.

With distribution networks and service centers located throughout the world, Alpha Technologies is here to back you up. From your date of purchase, Alpha provides complete technical support and prompt, reliable service to ensure that your CFR-UPS provides you with a lifetime of reliable operation.

The Alpha CFR-UPS

1. INTRODUCTION

1.2 The CFR Advantage

ADVANCED POWER PROTECTION TECHNOLOGY

Power protection devices can be judged by the type and quality of power they provide. Alpha CFR Uninterruptible Power Supplies provide continuous, conditioned “computer-grade” AC power to electronic equipment such as Computer Systems, Point of Sale Terminals, Process Controls, Telecommunications, CATV Headend, Broadband LAN, Manufacturing Control Systems, Critical Care and Hospital Lab Equipment.

Alpha's proven design virtually eliminates surges and spikes. The Alpha CFR UPS provides spike attenuation of 2000 to 1 and meets the requirements of IEEE 587 / ANSI 62.41.

Unlike many standby power systems, which regulate output voltage only when operating from their battery backup, the Alpha CFR UPS constantly maintains power. Even with input voltage fluctuations as great as +10% or -25%, the output remains constant, regardless of load.

Electromagnetic and Radio Frequency Interference (EMI and RFI) can damage semiconductors and have devastating effects on critical data. The CFR UPS input is tection from this type of interference. Measured in decibels (dB) of attenuation, Alpha's CFR achieves up to 120 dB common mode, and 60 dB normal mode.

Pins 7 and 8 of the ALARM INTERFACE connector provide EMERGENCY POWER OFF contacts. A switch contact can be hard-wired to the UPS to completely shut down the system in the event of an emergency, such as a fire.

In an emergency, the switch must be depressed (shorted) for at least

1.5 seconds. The UPS will shut down approximately 2 seconds after the signal is recognized. The switch, connected to pins 7 and 8, must be electrically isolated (up to 1500VAC isolation is recommended).

A system shut down in this manner will open the BATTERY circuit breaker. In the event there is an actual fire in the equipment room, the wire will melt causing as short circuit between pins 7 and 8 and open the BATTERY circuit breaker.

CAUTION: When the EPO switch is activated, the AC LINE connected to the UPS input may still be energized. To completely remove the power from the building, the MAIN AC LINE breaker must be switched OFF. Consult your national and local electrical codes for further information.

3. INSTALLATION

3.1 Pre-Installation

DO NOT CONNECT THE UPS TO A LINE CONDITIONER, ISOLATION TRANSFORMER OR ANY OTHER SIMILAR TYPE OF DEVICE. DAMAGE TO THE UPS AND THE LINE CONDITIONING EQUIPMENT CAN OCCUR.

Site Preparation

The UPS should be installed upright in a well-ventilated, dust free environment. The weight of the UPS, especially if it has an optional battery pack, is quite heavy (see specifications). Do not place the unit on any surface unable to fully support its weight.

Utility Circuit Breaker

The UPS should be installed on a dedicated circuit with a properly sized circuit breaker. Breaker size can be determined by adding 15% to the maximum input current of the unit (see specifications). For example, the CFR 600 draws 4.8 Amps of current. By adding 15%, the number becomes 5.5 Amps. In this case, a standard 15 Amp circuit breaker is suitable for use.

Grounding

Since the CFR UPS bonds output neutral to ground (qualifying it as a "separately-derived power source"), proper grounding is critical. Many older facilities may have an electrical system that is incapable of supporting this type of grounding requirement. To ensure optimum performance from your UPS, always install a hardwired ground. A qualified electrician should also inspect the existing wiring in the building prior to installation to verify proper grounding.

Standby Generators

The CFR is equipped with a frequency sense circuit, along with a constant slew frequency synchronization circuit, to optimize operation with most standby generators. Prior to installation, compare the output voltage of the generator to the voltage requirements of the UPS (see CFR nameplate label). If the UPS requires 240 VAC input and the generator produces only 208 VAC, it will cause the UPS to run continuously off of battery power. This would discharge the UPS batteries and cause the output load to fail.

Alpha Technologies recommends using a generator equipped with an electronic speed and voltage control. If a generator equipped with a mechanical governor "speed control" is used, this could also cause the UPS to run continuously in LINE FAILURE mode due to the unstable frequency of the generator.

The generator should also produce less than 10% voltage THD. Generators with a higher THD rating may cause the CFR UPS to switch to LINE FAILURE mode, and switch to battery operation, as the generator output would be sensed as a noisy utility.

3. INSTALLATION

3.2 Connecting the CFR

1. Connect the CFR's AC power cord to the wall receptacle.

2. If using an external battery pack, plug its connector into the rear panel of

the UPS (see section 3.3).

3. Start and test the UPS without the load connected (see section 4.1). After testing, switch the unit OFF before connecting the load.

4. Plug the equipment to be protected into the UPS rear panel receptacles. Note: The load should be switched OFF prior to connection.

5. Individually ground each piece of equipment connected to the UPS at the single point ground lug located on the CFR's rear panel. Note: Consult your local electrical code to ensure prescribed grounding practices.

THE UPS UTILIZES A TRANSFORMER TO PROVIDE EXCELLENT ISOLATION AND VOLTAGE REGULATION. DURING NORMAL OPERATION, THE UPS WILL BE WARM TO THE TOUCH, BUT NOT HOT ENOUGH TO BURN. THE TRANSFORMERS HAVE BEEN COATED WITH A LACQUER FINISH WHICH MAY PRODUCE A SLIGHT, NONTOXIC ODOR DURING THE FIRST SEVERAL WEEKS OF OPERATION.

THE UPS GENERATES EMR (ELECTROMAGNETIC RADIATION). KEEP

4.1 Start-up and Test

1. Plug the CFR’s AC line cord into a wall receptacle. The TEST LED and

OUTPUT LOAD display LEDs will flash for a few seconds to indicate the CFR is powering up. The LINE PRESENT LED will then come ON to indicate the AC input line is OK and the CFR is running on AC line power.

2. Switch the rear panel BATTERY circuit breaker ON to activate the battery circuit.

3. Test the UPS by unplugging the AC LINE cord from the wall receptacle. The front panel amber “LINE FAILURE” LED will light as the UPS initiates LINE FAILURE operation.

4. Plug the AC LINE cord back into the wall receptacle. The “LINE PRESENT” LED will come ON to indicate the presence of AC line power. Within 20 seconds, the “LINE FAILURE” LED will shut OFF to indicate that the UPS has resumed LINE PRESENT operation.

5. Once the UPS has been tested, switch the load ON, one unit at a time, and observe the front panel “OUTPUT LOAD” display. As each additional piece of equipment is switched ON, the LED’s will display the increased load up to 100%.

UPS Powering Up

Whenever the CFR is powering up, the TEST LED flashes for a few seconds. At the same time the OUTPUT LOAD indicator LEDs flash in a chasing pattern to indicate that there is no output. As soon as the power up sequence is completed, the TEST LED switches OFF and the OUTPUT LOAD display LEDs show the percentage of the load.

Output Shutdown Pending

The TEST LED will flash to indicate that a UPS output shutdown is pending to occur. When the operator gives an output shutdown command (either via the RS-232 serial port or by the LAN Interface port), the UPS delays the shutdown (for a programmable period) before actually switching off the output.

Output Shutdown In Progress

The five OUTPUT LOAD LEDs will flash in a chasing pattern whenever the CFR output is switched off by an output shutdown command (either via the RS-232 serial port or by the LAN Interface port). This will also occur when the unit is first powering up.

Line Synchronization

When both the “LINE POWER” and “LINE FAILURE” LEDs are ON, the

UPS is synchronizing its output frequency to the utility input prior to resuming AC line operation. Synchronization takes approximately 15 seconds. If the line frequency (generator frequency) is out of tolerance, the UPS can not synchronize to it, and stays in the inverter mode.

Low Battery Warning

The red “LOW BATTERY WARNING” LED precedes “LOW BATTERY SHUTDOWN” by 2 to 5 minutes and indicates that the batteries can no longer support the load. Immediate steps should be taken to begin an orderly system shutdown. From LOW BATTERY WARNING, it may take several hours to fully recharge the batteries.

Low Battery Shutdown

The “LOW BATTERY SHUTDOWN” LED indicates that the UPS has shut itself down to prevent over-discharge damage to the batteries. In critical applications, an additional power source (such as a generator) should be used until utility line power returns.

Test

The yellow “TEST” LED indicates that the UPS is simulating a LINE FAILURE to self-test the backup capabilities of the unit. If, during the one minute test, the UPS fails to supply backup power, it resumes LINE PRESENT operation without interruption to the load and lights the “SERVICE” LED.

5.1 Remote RS-232 Operation

Introduction:

This section of the manual describes how to monitor, control and calibrate the CFR-UPS using RS-232 ASCII commands and how to navigate through the program using the menu structure.

The RS-232 serial interface is designed to work with terminal emulation software in an interactive mode. Various parameters and commands may be accessed either through the menus or by typing the number associated with the desired functions. See section 5.3.

RS-232 menus have a hierarchical format. The top level menu, which is also called the OPENING MENU, can be accessed by pressing the ENTER key (which sends a carriage return character). This menu lists the numbers for accessing other sub-menus plus displays the current LINE status and pending ALARM conditions.

The figure below shows the typical opening menu screen which displays the menu options 1 through 7 followed by status and alarm messages. The INPUT LINE shows the current status of the AC line which may be PRESENT; FAILURE; or TEST MODE. The ALARMS message lists all current alarms. For a complete description of alarms refer to section 5.12.

5.4 Menu Commands Overview

Overview:

The following section provide a general overview of the menu structure and give some examples of how to perform certain command functions such as testing the UPS.

Querying CFR Status and Measured Parameters

The current status (mode of operation) of the CFR and all active alarms are displayed at the end of the opening menu (see section 5.12 for a list of status messages and alarm events). Press “ENTER” to query CFR status and alarms. Use commands “1” to “4” to query the battery temperature, input (line) parameters, output (load) parameters, and battery parameters. Command “0” is a special command which displays all of the UPS parameters together. This command is discussed in section 5.11.

Testing the CFR

Use commands “11” and “12” to start and terminate a self-test. During a self-test, the UPS switches to the inverter mode to test the battery and the inverter hardware. The test takes about one minute and, when complete an ASCII message is sent to indicate the result. You may also schedule a selftest using commands “53” to “55”.

Shutting OFF the Inverter to Save Battery

Commands “507” and “508” can be used when the UPS is in the inverter mode to switch the inverter OFF to prevent a deep battery discharge during extended line failures. The UPS-CFR switches to normal operation when input line is restored. Note: This command will drop the connected load.

Scheduling Output Shutdown/Reboot

The output of the UPS can be turned OFF by sending a RS-232 command. Commands “501” to “506” control the output shutdown feature. When the UPS receives a start shutdown command, “502”, it waits for the period specified in output shutdown delay, “505”, and then turns OFF the UPS output. The UPS remains in the shutdown mode for the mandatory down time specified by output shutdown duration, “506”. Depending upon the setting of the output shutdown recovery mode, “504”, the output is switched ON when the shutdown duration expires or when the input is restored. You start a shutdown whenever the shutdown delay is set using command “501” may cancel a pending shutdown by sending command “503”.

5. RS-232 TERMINAL COMMUNICATION

5.4 Menu Commands Overview,

Calibrating the CFR

The CFR-UPS may be calibrated using two sets of parameters Maintenance Parameters (commands “70” to “79”) and Service Parameters (commands “80” to “89”). Maintenance parameters allow you to customize the CFR detection and warning levels. There should be no need to change these setting unless wider or narrower detection tolerances are required.

T ransmitting Unsolicited Alarms

The UPS can automatically transmit alarm messages (in ASCII format) to notify a status change or a power problem as it occurs. You can enable or disable this option by using commands “510” and “509” respectively.

5. RS-232 TERMINAL COMMUNICATION

5.8 Battery Parameters

“BATTERY PARAMETERS” provides UPS Battery Voltage, Charger Current, and Charger Status information.

Voltage

Voltage indicates the average DC voltage of UPS batteries. When the UPS is running in “LINE PRESENT” mode and the batteries are charged, the voltage will be approximately 27.6 VDC (equal to the charger’s “FLOAT” charge). When the UPS is running in “LINE FAILURE” mode, the battery voltage will slowly decrease until the Battery Low Voltage Cutout is reached (approximately 21.0 VDC). Once utility power is restored, after a prolonged power outage, the battery voltage will slowly climb until the batteries are recharged. Note: If external batteries are connected, their voltage will be reflected as well.

Battery Current

When the UPS is running in “LINE PRESENT” mode, the average DC charger current is displayed (i.e., 2.1 Amps). When the UPS is running in “INVERTER” mode the battery charge current is zero (0).

Charger Status

When the UPS is in “LINE PRESENT” mode, the charger keeps the batteries charged, indicated by “CHARGER STATUS ON”. When the UPS is in “LINE FAILURE” mode and running on the batteries, the charger immediately switches OFF, indicated by the display “CHARGER STATUS OFF”. Once utility power returns, or an alternative power source (generator) is connected, the charger will switch ON and the DC current will slowly rise after an initial 3 second “soft start” delay.

5. RS-232 TERMINAL COMMUNICATION

5.9 User Parameters

“USER PARAMETERS” allows you to set the information for

automatic test, output voltage shutdown, display unit identification, and to

change the security codes. Whenever one of the USER PARAMETER items is accessed, you are prompted for a security code. Note: The code (1111) is preset at the factory and can be changed by entering the SET USER SECURITY CODE screen (menu item 58).

Unsolicited Alarm Messages

The CFR can transmit alarm messages (in ASCII format) to notify a

status change or a power problem. Once this feature is enabled, alarm messages are transmitted automatically on the RS-232 port as soon as the status of the CFR changes. You can connect a terminal to the CFR to monitor its status and log all power problems. Refer to menu items 56 and 509-511 for a detailed description.

Automatic Output Shutdown

The output of the CFR can be turned off by sending a command via

the RS-232 port using a computer or terminal. Refer to menu items 501508 a for detailed description (menu items 501-506 are intended for scheduled shutdown even when the AC line is present; 507 and 508 items can be used to switch the inverter ON and OFF to preserve the battery).

5.10 Maintenance Parameters

“MAINTENANCE PARAMETERS” allow you to customize UPS detection and warning characteristics. Normally, there should be no need to

change these factory settings. CAUTION: If any of these parameters are changed, it is vital to thoroughly test the UPS since an improper adjustment can render the unit useless. Since each parameter is viewed through reference numbers (1 - 16) and translated into a scale of “reasonable” adjustments, an increase or decrease of 2 - 3 reference numbers will have a noticeable affect. If you have questions, contact Alpha prior to making any adjustment.

Fast Detect Lo Ref

Increasing this value will make the UPS more sensitive to a fast, low amplitude line disturbance (glitch).

Fast Detect Hi Ref

Increasing this value will make the UPS more sensitive to a fast, high amplitude line disturbance (spike).

Medium Detect Lo Ref

Increasing this value will make the UPS more sensitive to a slow, low amplitude line disturbance (sag).

Medium Detect Hi Ref

Increasing this value will make the UPS more sensitive to a slow, high amplitude line disturbance (surge).

Slow Detect Lo Ref

Increasing this value will make the UPS more sensitive to a slow, low amplitude line disturbance (brownout) by raising the brownout detection level. Note: The Slow Detect Hys Lo Ref should also be adjusted by the same amount.

Slow Detect Hi Ref

Increasing this value will make the UPS more sensitive to a slow, high amplitude line disturbance (sustained overvoltage) by lowering the overvoltage detection level. Note: The Slow Detect Hys Hi Ref should also be adjusted by the same amount.

Slow Detect Hys Lo Ref

Increasing this value will raise the voltage level at which the UPS will resume LINE POWER operation after a line disturbance has been corrected. This setting should normally be 1 - 3 settings above the Slow Detect Lo Ref setting.

Slow Detect Hys Hi Ref

Increasing this value will lower the voltage level at which the UPS will resume LINE POWER operation after an overvoltage condition has been corrected. This setting should normally be the same, or 1 - 3 settings above, the Slow Detect Hi Ref setting.

5. RS-232 TERMINAL COMMUNICATION

5.10 Maintenance Parameters

Max. PLL Slew Rate

Increasing this value will reduce the speed at which the Phase Locked

Loop (PLL) will change the output frequency while the UPS resumes LINE PRESENT operation after a line fault has been corrected. It will also increase the time required to resume LINE PRESENT operation.

Battery Warning Ref

Increasing this value will increase the time before a LOW BATTERY

WARNING occurs, thus allowing the batteries to drain more of their charge before a warning is given. Decreasing this value will allow more run time between LOW BATTERY WARNING and SHUTDOWN.

5. RS-232 TERMINAL COMMUNICATION

5.12 Event Descriptions (Alarms),

Several alarms can be triggered during the same event. If there is a loss of AC line voltage, for example, the UPS may detect a glitch, low frequency and blackout.

Low Battery Warning (LO_BAT_WARN) - The batteries are near the end of their useful charge. If AC line power is not restored within a short period of time, output power will be lost. All systems should be shutdown immediately to prevent loss of data.

Low Battery Shutdown (LO_BAT_SHTDWN) - To prevent an overdischarge condition of the batteries, the unit has shutdown. Output power is terminated in this condition.

Battery Voltage High (BAT_VOLT_HI) - The charging voltage is higher than the threshold setting for the batteries. This could be the result of a defective charger, improper external battery connections, or defective batteries. Service the unit or batteries to correct condition. Note: This condition activates the SERVICE alarm, along with an audible alarm which can be cleared by pressing the ALARM OFF or MUTE key.

Failed Self-Test (FAIL_SELF_TEST) - The unit could not maintain output power while in the self-test mode. Check the batteries and circuit breakers. Note: This condition activates the SERVICE alarm, along with an audible alarm which can be cleared by pressing the ALARM OFF or MUTE key.

Battery Fault (BATT_FLT) - The battery charger is not able to supply the proper amount of current or voltage to the batteries. This condition usually indicates that the batteries are not connected or the BATTERY circuit breaker is switched OFF.

continued

Glitch (GLITCH) - A glitch is a fast, low amplitude line disturbance where

the input voltage drops momentarily (less than 8 ms). * *

Spike (SPIKE) - A spike is a fast, high amplitude line disturbance where the input voltage rises momentarily (less than 8 ms). * *

Sag (SAG) - A sag is a slow, low amplitude line disturbance where the input voltage decreases for 8 - 40 ms. * *

Surge (SURGE) - A surge is a slow, high amplitude line disturbance where the input voltage increases for 8 - 40 ms. * *

Brownout (BROWNOUT) - A brownout is a slow, low amplitude line disturbance where the input voltage decreases for a long period of time (greater than 16 ms). * *

Slow Surge (SLOW_SURGE) - A brownout high (high overvoltage) is a slow, high amplitude line disturbance where the input voltage increases for a long period of time (greater than 16 ms). * *

* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.

5. RS-232 TERMINAL COMMUNICATION

5.12 Event Descriptions,

Blackout (BLACKOUT) - The blackout alarm is triggered when the input

voltage is lost for 12 ms, or when the RMS input voltage is less than 1/2 the nominal voltage for 100 ms or longer. * *

Frequency High (FREQ_HI) - A frequency high alarm is triggered when

there is a power line problem where the input frequency increases beyond the preset limit. * *

Frequency Low (FREQ_LO) - A frequency low alarm is triggered when

there is a power line problem where the input frequency decreases beyond the preset limit. * *

Output Voltage Low (VOLT_LO) - The output voltage low alarm

indicates that the output of the UPS is too heavily loaded, or there is a fault within the UPS. Reduce the load connected to the UPS.

Output Voltage High (VOLT_HI) - The output voltage high alarm can be

caused by some equipment which draws power at irregular intervals. Disconnect all equipment from the UPS and determine whether the fault will repeat. If it does, the unit may be out of calibration, or there is an internal fault causing the overvoltage condition. Have the unit serviced by an authorized Alpha Repair Depot.

Output Power Overload (PWR_OVLD) - The output power overload

alarm indicates a condition where the output of the UPS is too heavily loaded. If this is not corrected, the unit may go into a shutdown condition to protect the UPS's internal circuitry.

Output VA Overload (VA_OVLD) - The output VA overload alarm is

triggered when the RMS current exceeds the rating of the UPS. Reduce the load on the output of the UPS to prevent overheating.

continued

Output Over Voltage Fault (OVER_V_FLT) - The output overvoltage

fault alarm indicates a malfunction has been detected in the control circuit. The output voltage has been shut off to protect the load from an overvoltage condition.

Output Short Circuit (SHORT_CCT) - The output short circuit alarm

indicates a load was connected to the UPS that was shorted. This could be caused by a miswired AC power cord or equipment connected to the UPS that is in need of repair. Note: This condition activates the SERVICE alarm, along with an audible alarm which can be cleared by pressing the MUTE key.

Internal Temperature High (AMB_TEMP_HI) - The internal tempera-

ture high alarm indicates that the temperature of the UPS, measured by internal circuitry, was found to be too high. This could be caused by a sustained overload on the output of the UPS, a blocked fan (if equipped), or operating the unit in an excessively high ambient temperature. To prolong the life of the batteries and UPS components, determine and correct the cause of the over-temperature condition.

* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.

5. RS-232 TERMINAL COMMUNICATION

5.12 Event Descriptions,

Input Line Fail - Indicates that the UPS switched to backup power to

protect the equipment for one (or more) of the above conditions. * *

Normal Line Mode - Indicates that the UPS is drawing power from the AC line and charging the batteries.

Test Mode - Indicates the UPS was put into a test mode condition either by the TEST SCHEDULE routine or by pressing the TEST button on the Intelligent Interface Device's panel. The unit will switch to backup power while in the test mode. * *

Float Charge Mode - This is the normal operating mode of the battery charger. During LINE PRESENT operation, the batteries constantly receive a "Float" charge voltage to ensure that backup power is available when required.

Service Codes (1-6) - These codes indicate a potential fault within the UPS. Call Alpha Customer Support and report any displayed Service Codes. Also refer to the Troubleshooting section (6.7) of the manual.

Serv Code 1 - Phase Lock Loop Failure. The phase lock loop circuitry has failed to lock onto the AC input LINE due to instability of the frequency. If the UPS is operating from a generator, check the frequency and adjust it if necessary.

Serv Code 2 - Micro software reset. The internal “watch dog” circuit has detected a fault and reset the software. Contact Alpha to help determine the cause of the fault.

Serv Code 3 - Micro hardware reset. A micro hardware reset is activated as part of the power on condition. If this alarm occurs during normal operation, it may indicate a malfunction in the hardware circuitry. Contact Alpha to help determine the cause of the fault.

Serv Code 4 - Power board EEPROM fault. The EEPROM on the power board contains the unit configuration information. If this fault occurs, it signifies either the configuration information has been corrupted, the EEPROM has malfunctioned, or there is a loose connection inside the UPS.

continued

Serv Code 5 - Power board hardware fault. The control circuitry on the

power board has detected a hardware fault condition which impedes correct operation of the UPS.

Serv Code 6 - Neg DC supply rail fail. The negative voltage power supply to the microcontroller has malfunctioned.

EMGNCY POFF - Emergency power shutdown.

OUTV SHTDWN - See menu 505 & 506 (see section 5.9).

* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.

6. MAINTENANCE

6.1 CFR Maintenance

The electronic components used in the UPS require no maintenance. If

the unit fails to perform a specific function, refer to the troubleshooting guide. The guide lists typical symptoms, causes and solutions that apply to the UPS, starting with the most obvious and working systematically through the unit.

By establishing a routine maintenance program and following the

guidelines contained in this manual, your Alpha CFR will continue to provide years of trouble-free service.

6.2 Battery Maintenance

The maintenance free batteries used in the UPS will be affected by many

variables including operating temperatures, number of discharges over the life of the battery, charging characteristics, and low voltage cell cutoff. The Alpha CFR complies with all factory recommendations for charging and discharging batteries to ensure optimum performance and the longest possible battery life.

During normal operation, the UPS batteries will tend to increase in

capacity over the first three to twelve months of service. There can be as much as a 20% increase in available backup power after the first ten to fifteen battery discharges. Once the batteries reach this peak, they will slowly begin to lose capacity until, eventually, they will be unable to provide the required backup power.

Note: Battery terminals vary in size and shape.

Figure 13

Typical UPS Battery

6. MAINTENANCE

6.3 Battery Testing

To determine the maximum amount of battery run time available, run this

test at least once a year. The length of the test can vary from several minutes to many hours and should not be done during critical applications. Since the test discharges the batteries, backup power may not be readily available (for several hours) in the event of a utility power failure.

1. Unplug the AC Line cord from the wall receptacle. The front panel “LINE FAILURE” LED will come ON. Make a note of the START time.

2. When the CFR reaches LOW BATTERY WARNING, record the time. Subtract the START time to determine the actual safe run time. To cancel the test, plug the AC Line cord back into the wall receptacle.

3. To determine the reserve time available, allow the UPS to continue until it reaches LOW BATTERY SHUTDOWN. Warning: This will cause the load to go down. Make a note of the time. Subtract the LOW BATTERY WARNING time to determine your available reserve time.

4. Switch the load OFF. Plug the AC Line cord back into the wall receptacle. The “LOW BATTERY WARNING” LED will remain ON until the batteries are partially recharged. Switch the load ON, one device at a time. To determine recharge time, subtract the time you resumed LINE PRESENT operation from when the “LOW BATTERY WARNING” LED goes OFF.

TO PREVENT THE POSSIBILITY OF INJURY TO SERVICE OR EMERGENCY PERSONNEL, ALWAYS SWITCH THE UPS REAR PANEL BATTERY CIRCUIT BREAKER(S) OFF TO DEENERGIZE THE CIRCUIT.

EMERGENCY SHUTDOWN PROCEDURE:

1. Switch the rear panel BATTERY circuit breaker OFF.

2. Unplug the AC power cord from the wall receptacle or the back of the unit. If hardwired, switch the main panel AC breaker to the UPS OFF
