You must read and understand the following warnings before installing the Alpha FXM and its components. Failure to do so could result in personal injury or death.
• Read and follow all instructions included in this manual.
• Do not work alone under hazardous conditions.
• Only qualified personnel are allowed to install, operate and service this system and its components.
• Use proper lifting techniques whenever handling equipment, parts, or batteries.
• Always assume electrical connections or conductors are live. Switch off all circuit breakers and double-
check connections with a voltmeter before performing installation or maintenance.
• Place warning label(s) on the utility panel to tell emergency personnel a UPS is installed.
• The Alpha FXM uses more than one live circuit. AC power may be present at the outputs even if the system
is disconnected from line or battery power.
• The Alpha FXM surface can be very hot to the touch.
• Battery installation and servicing should be done or supervised by personnel knowledgeable about batteries
and their safety procedures.
• If electrolyte splashes on your skin, immediately wash the affected area with water. If electrolyte gets into
your eyes, wash them for at least 10 minutes with clean running water or a special neutralizing eye wash
solution. Seek medical attention at once.
• Neutralize spilled electrolyte with special neutralizing solutions in a “spill kit” or a solution of 1 lb. (0.45 kg) of
baking soda (bicarbonate of soda) in 1 gallon (3.8 L) of water.
• Be extra cautious when connecting or adjusting battery cabling. An improperly connected battery cable or
an unconnected battery cable can result in arcing, fire, or explosion.
• Use new batteries when installing a new unit. Verify that all batteries are the same type with identical date
codes.
• Always replace batteries with ones of identical number, type and rating. Never install old or untested batteries. One sealed lead-acid battery is rated to a maximum voltage of 12 Vdc.
• A battery that shows signs of cracking, leaking or swelling must be replaced immediately by authorized personnel using a battery of identical type and rating.
• Keep the chassis area clear and dust-free during and after installation.
• Keep tools away from walk areas where you or others could fall over them.
• Wear safety glasses when working under any conditions that might be hazardous to your eyes.
• Do not work on the unit or connect or disconnect cables during periods of lightning activity.
• Do not smoke or introduce sparks in the vicinity of a battery.
• Never open or damage the batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic
and hazardous to the environment.
• A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:
a. Remove watches, rings, or other metal objects.
b. Use tools with insulated handles.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect the charging source before connecting or disconnecting battery terminals.
f. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source from the
ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such
shock can be reduced if the grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).

3. Site Planning
WARNING!
Restricted Access: The Alpha FXM must be installed in a restricted area accessible only
by qualied service personnel.
The Alpha FXM is intended for permanent AC connection only. The only exception is the
FXM650(U) model.
The Alpha FXM must be correctly grounded for proper operation. Older facilities may
have inadequate electrical grounding. Inspection must be performed by a qualied electrician before installation to ensure that grounding meets the local electrical code.
The utility line attached to the Alpha FXM input MUST be protected by a circuit breaker
certied for this use in accordance with the local electrical code. The UPS must be connected only to a dedicated branch circuit.
The UPS equipment that is powered by this service panel requires the neutral to be permanently bonded to the ground. Always disconnect the batteries before servicing the
circuit breaker panel.
The input and output lines to and from the Alpha FXM MUST have disconnect devices
attached.
The Alpha FXM is suitable for installations in Network Telecommunication Facilities and locations where the
National Electrical Code applies.
Grounding: The Alpha FXM is suitable both for installation as part of a common bonding network and an isolated bonding network.
For installations above 1400 m (4500 ft) elevation, additional cooling may be needed to reduce the operating
temperature of the Alpha FXM. The maximum allowable operating temperature must be reduced by 2°C (3.5
°F) for every 300 m (1000 ft) above 1400 m (4500 ft).
3.1 Safety Precautions
• Install the Alpha FXM on a surface that can support its weight. See Chapter "9. Specifications".
• The input wiring must reach a suitably grounded power outlet and the load wiring must reach the
Alpha FXM output terminal blocks.
• Place the Alpha FXM in a properly sheltered location or inside a weather-proof enclosure to protect the
electronics from water, dust and other possible contamination.
• Alpha Technologies offers a wide range of outdoor enclosure systems. Visit our website at www.alpha.ca,
or call customer service for more information.
• Backup Generator (If used)
Use Generator mode so that noise tolerance is increased to accept the fluctuations created by a generator. See Sense Type in Table B on page 24 .
Use a generator with electronic speed and voltage controls which produces less than 10% voltage total harmonic distortion (THD). Mechanical governors can force the Alpha FXM to run continuously in the
Inverter mode.
Before installation, make sure the generator’s output voltage is compatible with the Alpha FXM input voltage requirements. To make sure the system runs smoothly, use a generator that supplies twice as much
power as drawn by the total load.

5.3.3 Procedure
1. If used, connect the following ports (see Figure 1 on page 7 for location of numbered elements):
• Ethernet port 4.
• RS-232 port 7.
• Dry contacts 9.
• User inputs 10.
2. Connect the load to the Alpha FXM Output terminal block 14. Torque to 1.4 N-m (12 lb-in).
3. Connect the line power to the Alpha FXM AC Input terminal block 13. Torque to 1.4 N-m (12 lb-in).
4. If needed, attach the terminal block covers and battery harness restraining bracket.
WARNING!
Before proceeding, verify that the line wire is attached to the line terminal block, the
ground wire is attached to the ground terminal block, and the neutral wire is attached to
the neutral terminal block to prevent accidental shocks or electrocutions.
5.4 UATS and (UGTS) Option
The Universal Automatic Transfer Switch (UATS) and Universal Generator Transfer Switch (UGTS) are the next
generation of Automatic Transfer Switch (ATS) and Generator Transfer Switch (GTS) products. They are optional
add-on switching units specifically designed for the FXM UPS family (FXM 650, 1100 and 2000), the Micro UPS
family (Micro 300 and 1000) and the Alpha FXM350/ Micro350 UPS. These switching units provide power and/or
bypass capacity (automatic or manual) so that the operator may safely disconnect the UPS from line or generator
power for easy removal and servicing. In bypass mode, the loads are directly connected to the line or generator
power without any conditioning. Depending on the use of one and/or the other, the UATS/UGTS allows the use
of up to 3 different back-up sources (line, batteries and generator). Refer to the UATS/UGTS Installation Manual
(Alpha P/N 020-165-B0) for details.
WARNING!
Make sure you have read and understood the instructions given in the UATS/UGTS Installation Manual before making any connection to the supply.

6. Operating the Alpha FXM
6.1 Switching the Alpha FXM On and Off
Under normal operation, the Alpha FXM is always powered ON to supply uninterruptible power to the load.
Switching off the Alpha FXM will disconnect the power supply to the load. If for any reason you need to switch
off the Alpha FXM while maintaining power to your critical load, make sure that you have a plan that provides an
alternate source of power.
6.1.1 Switch Off Procedure
1. Switch off the AC input circuit breaker.
2. Switch off the battery circuit breaker.
The status LED turns off and the LCD panel goes blank. The Alpha FXM is now switched off and no backup
power is supplied to the load.
6.1. 2 Switch On Procedure (LINE mode)
Before you put the Alpha FXM back into commission, make sure that the line is qualified and the batteries are
fully charged.
1. Switch on the battery circuit breaker. The LCD displays STANDBY and the fan turns on for about a minute. If
the temperature is below –15ºC, the LCD display may not function. See Chapter "8. Troubleshooting".
2. Switch on the AC input circuit breaker. The Alpha FXM qualifies the line power. The LCD displays RETRAN,
then shows LINE, BUCK or BOOST. The status LED illuminates.
3. If there is no line power, the Alpha FXM remains in the STANDBY mode until the line power is qualified. To
provide backup battery power to the load, perform a manual start by using the Inverter command: From
the Control Menu, scroll till the LCD displays Inverter, press Select and select ON. (See Figure 11 on page
23).
The Alpha FXM uses auto-frequency detection. When it is first switched on, it senses the line frequency and adjusts its output frequency to match that of the input. The load should be receiving power, If not, perform troubleshooting.
6.1.3 Switching the Alpha FXM from Line mode to Inverter mode
You can force the Alpha FXM to operate in the Inverter mode by manually switching off the input circuit breaker.
Doing so will effectively disconnect any line power to the Alpha FXM, simulating a power outage which triggers
the Alpha FXM to switch to the inverter mode of operation.
Procedure
1. Switch off the input circuit breaker. The LCD shows INVERTER, the status LED starts flashing to show that
the Alpha FXM is running on backup battery power. Confirm that the load is receiving power.
6.1.4 Switching the Alpha FXM from Inverter mode to Line mode
The Alpha FXM remains in the Inverter mode for as long as the input circuit breaker is switched off. Backup power is provided to the load until the batteries are drained to a preset level which triggers the Alpha FXM to shutdown automatically. If it is not necessary to operate the Alpha FXM in the Inverter mode, switch the Alpha FXM
back to the Line mode as soon as possible.
Procedure
1. Switch on the input circuit breaker. The Alpha FXM qualifies the line power. The LCD displays RETRAN, then
shows LINE, BUCK or BOOST. The status LED illuminates.
If the Alpha FXM constantly switches between Inverter and Line modes because of a noisy line, broaden the
input parameter tolerances from Normal to Generator. See Sense Type in Table B on page 24.

Normal: The Alpha FXM can operate successfully with most line conditions.
OR:
Generator: This setting increases noise tolerance so the uctuations created by
a generator are acceptable. (A noisy line can cause the Alpha FXM to constantly
switch between inverter and line modes.)
The Functional mode can be changed when the Alpha FXM is in any mode (Table C
and "Table V — Boost/Buck/Line Transfer Thresholds" on page 82).
Automatic Voltage Regulation (AVR): Buck and boost modes are active.

should be done by a qualied technician acting under the instructions of Alpha
Technical Support (1 888 462 7487). Failure to contact Alpha Technologies before
performing this procedure could void your warranty.
Enable (default) allows the unit to detect and automatically congure the AC input
frequency (50Hz or 60Hz).
In cases where the AC input frequency can be out of range for long periods,
Disable prevents the unit from switching back and forth between 50Hz and 60Hz.
The frequency can only be changed when the Alpha FXM is in Standby mode—to
50 Hz or 60 Hz. This change should ONLY be done by a qualied technician acting
under the instructions of Alpha Technical Support (1 888 462 7487). Failure to
contact Alpha Technologies before doing this procedure could void your warranty.
Set how long it takes for the Alpha FXM to return to Line mode after the line has
become requalied to make sure the line is stable. The factory default setting
is 3 seconds. User adjustable in increments of 1 sec until 1 minute, and then in
increments of 1 minute to 15 minutes max.
When Disable is selected the default FXM inverter cutoff threshold is used.
When Enable is selected the user congured inverter cutoff threshold voltage is
used.

AC Output Shutdown
When this function is switched On, the Alpha FXM inverter is shut off. Neither line nor inverter power is supplied to the load.
DC Output Shutdown
When this function is switched On, the LVD configured relay will be de-energized (Off).
Applies when ANY programmable dry contact is programmed to be the Low Voltage Disconnect indicator.
See "UPS Maintenance > Relay & Load Shed" on page 41. When the function is switched from On to Off, a 10
second delay occurs before the LVD congured relay is energized.
Automatic Frequency Detection
This setting is enabled by default and allows the unit to detect and automatically configure the AC input
frequency (50Hz or 60Hz).
In cases where the AC input frequency can be out of range for long periods, disabling the automatic configuration prevents the unit from switching back and forth between 50Hz and 60Hz.

UPS Maintenance > Battery
Setting the Battery Charging Method to Standard or Bulk in the Battery Primary Configuration table
determines which parameters can be set or adjusted. See Figure 22 and Figure 23. The Standard charging
method is the default setting.
Standard Charging Method
Standard Charger Mode
Auto: Charger stops charging when the battery is
fully charged.
Constant: Charger switches to float mode when the
battery becomes charged. Float voltage is 0.4V lower
than maximum charging voltage and is temperature
compensated.
Temperature Compensation
Adjustable from 0 to -6.0 in increments of 0.5.
(Factory default is -5 mV/°C/Cell)
Max Charger Current
Charging current can be set to 0 or any value
between 2A and maximum in increments of 1A
(maximum = 15A for FXM1100/ FXM2000 and 10A for
FXM650). Charging current cannot be set to 1A.
When charging current is set to 0A, charger will stop
charging.
Low Battery Warning
Battery voltage value that activates the low battery
warning alarm. For the range of 24V and 48V
settings, refer to the Low Battery Warning entry in
Table I on page 65. The alarm is removed when
battery voltage is 2V above the warning setting for
a 48V battery, or 1V above the warning setting for a
24V battery.
Peukert Number
Refer to Appendix A to calculate the Peukert number.
Capacity
Rated capacity (Ah) of the battery shown on the
battery data sheet. Do not confuse the battery
capacity with the Peukert capacity.
Battery Open Circuit Voltage
Obtain this number from the battery data sheet. The
value is for a single battery, so for a 48V system with
4 batteries connected in series, multiply the number
by 4. For a 24V system with 2 batteries connected in
Figure 22 — UPS Maintenance: Battery,

017-230-B4 Rev B
NOTE:
The Battery Runtime Remaining algorithm attempts to calculate the health of the battery to get a more accurate
prediction of the remaining battery runtime. An accurate estimate of the battery health requires that at least one
battery discharge greater than 20% depth of discharge has taken place since the unit was switched on. When
the unit is powered up from an off state, the algorithm assumes that a new battery is connected to the unit. Each
discharge of greater than 20% will result in a new calculation for the relative battery health. This value is then
used in the Battery Runtime Prediction algorithm to compensate for an aging battery. We recommend that the
user set up a periodic (every 6 months) battery test with a depth of discharge of at least 20%.
The Battery Runtime Remaining algorithm relies heavily on the battery voltage to predict the remaining runtime.
This results in a less accurate predicted runtime during periods when the battery voltage is changing rapidly. The
battery voltage typically changes rapidly during the first few minutes of discharge when the unit switches from
charging to discharging while the unit is in the Inverter mode. The battery voltage may also change rapidly during
the last 20% of the discharge time when the battery is almost drained.
Bulk Charging Method
The Battery maintenance page has two tables: Battery Primary Configuration and Battery Configuration.
In the Battery Primary Configuration table, select Bulk battery charging method.
Figure 23 — UPS Maintenance: Battery, Bulk charging method
In the Battery Configuration table, Temperature Compensation (default 0.0mV/Cell/°C for bulk charger) and
Max Charger Current have the same function as the Standard charging method.
The following three parameters are only available when the Bulk battery charging method is selected:
Parameter 48V 24V
Default Minimum Maximum Default Minimum Maximum
Max Charger Voltage (Vdc) 53.5 52 56 26.8 26 28
Float Charger Voltage (Vdc) 53.5 52 56 26.8 26 28
Low Voltage Warning*(Vdc) 44 44 47 22 22 23
*Low voltage warning value has to be higher than Low Voltage Disconnect and lower than Low Voltage

Inverter Enabled/Disabled
Enabled: the inverter can function depending on the setting of the Inverter On/Off field.
Disabled: the FXM will not go into Inverter mode when it loses AC power.
Inverter On/Off
Selecting inverter On/Off will not turn on the inverter unless inverter is enabled first.
Inverter Off Delay Time
Used to set a delay before the inverter switches off to allow time for switching off critical loads. The set Inverter ON/OFF delay is only available when the Alpha FXM is in the Battery or Standby modes.
The delay can be adjusted in 1 second steps with a default setting of 0 seconds to a maximum of 600 seconds (10 minutes). The delay is only available in the Standby or Inverter modes. Once the Alpha FXM returns
to the Line mode, the delay resets to 0 seconds.
Inverter Cutoff Enable/Disable
Enabled: the user configured inverter cutoff threshold is used.
Disabled: the default FXM inverter cutoff threshold is used.
Inverter Cutoff Threshold
Defines the point where the unit will switch from Inverter to Standby when the battery is considered to be low
or in order to preserve the battery.
The inverter cutoff threshold is configurable in 0.1Vdc increments according to the battery voltage as described in the following table.

You can assign a dedicated timer to a dry contact. Upon entering the Inverter operating mode, the timer is activated and begins to count down from a user defined value. When the timer reaches zero, the programmed dry
contact relay is activated (Status = ON).
Figure 26 — Programmable Timer Operation
An example of a typical application of this timer-controlled dry contact function is control of a traffic light. When
the grid power fails, the Alpha FXM goes into the Inverter mode and continues supplying backup power to the
traffic light. Since the batteries supplying the backup power have limited capacity, a timer controlled dry contact
is usually configured to switch the traffic light into the flashing amber or flashing red mode after a user-defined
period to conserve battery power.
This setup works for non-rush hour traffic, but during rush hour, it may be desirable to keep the traffic light running normally as long as backup power is available. To address this issue, a new feature called the Time of Day
Action has been added to deactivate the timer during a user defined time period up to twice each day.
42
Figure 27 — Time Of Day Action Operation
017-230-B4 Rev B
You can define up to 2 peak time periods of the day in the Maintenance > Relay & Load Shed screen:
1. In the Time of Day Action Configuration dialogue box, set up the start and end time of the first rush hour
under Time Period 1 and the second rush hour under Time Period 2. In this example, during the first time
period (7 AM to 9 AM), all 3 timers are disabled (they do not count down at all). Similarly, all timers are
disabled during the second time period (3 PM to 6 PM).
2. Select ON under each time period. Click the Update Configuration button under the time periods to store the
settings.
Figure 28 — Time Of Day Configuration
3. Confirm your settings in the UPS Monitoring > Relay & Load Shed > Time of Day Action Status screen.
Once the Time of Day Action is configured, the Alpha FXM will automatically disable the timers during the Inverter
mode at the defined peak periods.
You can switch off the Time of Day Action by setting one or both time period(s) to OFF (Figure 29). The dry contact will be activated by the timer regardless of the peak period settings.

Controlling the external fan with a temperature triggered dry contact
The Temperature trigger has a user configurable range of +20°C to +55°C (68 – 131 °F). When the battery
temperature (monitored by the Battery Temperature Probe) reaches the threshold, the assigned relay closes and
turns on the external fan.

6.3.9 Keep Alive
Activation of the Keep Alive feature provides a method to restore communications when a communication failure
is detected. A reset temporarily removes power and resets the local communications equipment powered by this
unit.
54
Figure 48 — Keep Alive feature
017-230-B4 Rev B
Keep Alive Method to detect communication failure:
a. Ping is the only option in the Protocol field.
b. In the IP Address field, enter the IP address of this FXM.
c. In the Delay Between Retry field, enter the delay between pings: minimum = 5 sec, maximum = 65535
sec.
How to detect communication failure:
a. In the Timeout field, enter the ping timeout. Minimum = 2 sec, Maximum = 65535 sec.
b. In the Retries Before Failure field, enter the number of pings to repeat before power cycling.
Minimum = 1, Maximum = 20.
Keep Alive action to attempt to restore communication:
a. The Action field has 3 options: reset all power (AC and DC), reset AC power, and reset DC power. This
action resets the power for the duration set in Step b.
b. The Action Duration field is how long the output will be shut off by the UPS, Minimum = 5 sec,
Maximum = 3600 sec.
When To Fail:
a. The After X Consecutive Actions field determines the number of times the UPS will go through the ping
and power down and back up cycle before registering an alarm for Keep Alive. Other alarms and events
will occur regardless of this value. After the final power cycle, the UPS will issue another ping after the
Delay between retry has elapsed. This ensures the destination IP is not alive. The UPS will then set the
Keep Alive alarm. Minimum = 1, Maximum = 20.
Keep Alive Failure:
a. The Send Trap field allows the email and SNMP trap notification to be switched on and off for the Keep
Alive only.
b. The Delay to Re-Startup field configures the delay after the Keep Alive alarm is set and the next ping is
sent in delay to restart. Minimum = 5 sec, Maximum = 3600 sec.
Operation of the Keep Alive Feature
When [Status] is [On], the feature is enabled as follows:
1. Wait for [Delay To Startup] seconds and ping the [IP Address] every [Delay Between Retry] seconds.
2. When a ping fails, wait for [Timeout] seconds before doing another ping. If the ping still fails, repeat this
process [Retries Before Failure] times.
3. After retrying for [Retries Before Failure] times and pinging still fails, perform the selected [Action] for [Action
Duration] seconds.
4. Wait for [Delay Between Retry] seconds before pinging again.
5. If the ping still fails, repeat the last three points (3-5) for [After X Consecutive Actions] times.
6. If the ping still fails, activate the Keep Alive alarm and if [Send Trap] is [On], send a trap.
The unit then waits for [Delay To Re-Startup] to start the whole thing again.

Controlling the external fan by temperature triggered dry contact
The Temperature trigger has a user configurable range of +20°C to +55°C (68 – 131 °F). When the battery
temperature (monitored by the Battery Temperature Probe) reaches the threshold, the assigned relay closes and
turns on the external fan.
1. Assign the Temperature trigger function to an available dry contact, (for example, c1=11, where 11 is the
assigned index for the Temperature trigger function.)
2. At the HyperTerminal screen prompt, type Temp and press Enter to display the current temperature setting.
For example the Alpha FXM might return *temp=20.
3. To change the value to +35°C, type temp=35 and press Enter. The Alpha FXM returns *temp=35 as
confirmation.

7.1.2 Upgrading using the Web Interface
This feature is available if the FXM has a network interface card. See the procedure in Section "6.3.6 Upgrade
Files" on page 50.
7.2 Testing and Replacing the Batteries
7.2 .1 Battery life
Batteries lose their ability to store power as they age. Regularly test the batteries to ensure that they can continue
providing reliable service. Battery life is reduced by three major factors:
• Temperature – higher ambient temperatures, especially above 25°C, will reduce battery life. For example,
an average operating temperature of 27°C will likely reduce the life of the battery by 25%. Ensure that the
Alpha FXM and batteries are situated in a well ventilated area with adequate temperature control. A cool
environment is preferable.
• Number of discharge cycles – the more frequent the batteries are discharged, the shorter the battery life.
Frequent power outages imply the need for more frequent battery replacement.
• Depth of discharge – the longer the batteries are required to provide back up power, the shorter the battery
life. Frequent full discharging and the associated recharging of the batteries reduces the life. Shut down the
electrical load or return to primary power as soon as possible to extend the battery life.
7.2.2 Battery Run Time
The chart below shows typical run times (time to full discharge) for the standard batteries supplied with this unit.
These runtimes are for batteries in new and good condition. The run time performance will deteriorate over time in
a progressively decreasing curve.

7.2 .3 Battery Maintenance
The batteries supplied with this unit are sealed and maintenance free. Regularly ensure that all connectors are
tight and free of corrosion. The presence of corrosion, swelling of the battery case, or distortion in the shape of
the case suggests that the batteries need to be replaced.
7.2 .4 Battery Conductance Test (Optional)
1. Place the conductance meter probes across Battery #1.
2. Record the voltage and Siemens values in a log book.
3. Repeat for batteries #2, #3 and #4.
A new AlphaCell 180GXL battery has a conductance reference value of 1100 Siemens at 25°C. When this value
drops to 550 Siemens or 50% of the new battery reference value, the battery capacity is suspect of being below
80% and should be evaluated further. When the temperature of the batteries is not between 20°C and 30°C, use
the following temperature compensation values.
Table O — Battery Temperature Compensation Values
Battery Temperature Reference Value New 180GXL Suspect Value
35°C or higher 1183 592
30°C 1140 570
25°C 1100 550
20°C 1063 532
15°C 1028 514
10°C 995 498
5°C 965 483
0°C or colder 936 468
7.2 .5 Replacing the Batteries
Replace the batteries according to the results of the self test or the presence of terminal corrosion, swelling of
the battery case, or distortion in the shape of the case. New batteries will normally provide longer run times than
older ones. Larger capacity batteries may be available. Contact Alpha Technical Support (1 888 462 7487) to
order replacement batteries or to obtain assistance. On-site service may be available in your area.
Tools and Materials Required
• AC/DC voltmeter or multimeter.
• Labels or masking tape and marker.
• Torque wrench.
• Slot head screwdriver to fit the terminal blocks.
• High strength, flame-proof tape such as duct tape.
• Battery terminal corrosion inhibitor (such as NOCO Company’s NCP-2 or Sanchem Inc.’s No-Ox ID Grease
“A”).

WARNING!
Read and understand the battery safety instructions in “Product Safety Information”.
CAUTION!
Make sure all the replacement batteries are of the same type and rating. Failure to do so
could result in improper charging and damage to the batteries.
The Alpha FXM cannot provide backup battery power while the batteries are being replaced. If the line becomes
unqualified while the batteries are being replaced, the Alpha FXM shuts down and no power is provided to the
load.
Procedure
1. The Alpha FXM must be in the Line state. If it isn’t, wait until the line is qualified before proceeding.
2. Switch the Alpha FXM into the Bypass State by doing one of the following:
a. From the Alpha FXM control panel, navigate to the UPS Control Menu > BYPASS. Press the SELECT
button once OFF is flashing. Press the SCROLL button once ON is flashing. Press the SELECT button
once ON is displayed continuously, indicating that the Alpha FXM has been switched into the Bypass
state.
b. From the Alpha UPS Monitor main screen, go to the UPS Maintenance > Unit Configuration screen.
Switch on the Bypass Mode by clicking the ON button and then the Update Configuration button.
The Alpha FXM responds by displaying a “Bypass State” alarm. This is normal and does not indicate a
problem. It will clear itself when the Bypass state is subsequently disabled.
3. Switch off the battery circuit breaker.
4. Replace the batteries.
5. Switch on the battery circuit breaker.
6. Switch the Alpha FXM out of the Bypass state by switching the Bypass Mode OFF.

Perform preventative maintenance on the Alpha FXM module every 6 to 12 months. For mission critical applications such as backup traffic intersections, more frequent maintenance should be done. Proper implementation of
the following procedure will insure that your system continues to provide reliable backup power in the event of a
utility power failure.
7.3.1 Tools and Materials Required
• Wrench set.
• Labels and marker to number batteries.
• Conductance meter for optional conductance test.
7.3. 2 Procedure
1. Inspect the Alpha FXM and wiring for any physical damage. Repair or replace as required.
2. Verify that all connections are securely fastened. Tighten if necessary.
3. Inspect the batteries for cracks or swelling. Replace all four batteries if any of the batteries are cracked or
swollen. Replace only a faulty battery if an Alphaguard battery balancer is installed.
4. Inspect the battery terminals for corrosions. Clean and apply a corrosion prevention compound such as
NOCO Company NCP-2 or Sanchem Inc. NO-OX-ID if required.
5. Re-tighten the battery terminal bolts on Insert Terminal batteries. Re-torque the battery terminal bolts on Flag
Terminal batteries to the manufacturers specifications on if required.
6. Label the batteries #1, #2, #3 and #4. The battery negative cable from the Alpha FXM is connected to Battery
#1, and the battery positive cable from the Alpha FXM is connected to Battery #4.
7. Verify that the battery temperature probe is securely taped to the side of either battery #2 or #3.
7.3.3 Operational Test
1. Activate the Alpha FXM self-test function.
2. After passing the self-test, disconnect the AC input to the Alpha FXM to trigger the Alpha FXM into the
backup (Inverter) mode.
3. Let the Alpha FXM operate in the backup mode for approximately 10 minutes.
4. Measure the individual battery voltages while the Alpha FXM is operating in the backup mode. There should
be no more than 0.6 volts difference between the highest battery voltage and the lowest battery voltage.
CAUTION!
A battery that measures 2V lower than the other three batteries in the string probably
has a shorted cell. Replace all four batteries.
Three batteries in the string measuring the same voltage and one battery measuring
several volts higher indicates an open cell in the battery with the higher reading. Replace all four batteries.
5. Verify that there is no Low Battery Alarm.
6. Reconnect the AC input.

Appendix A - Peukert Number and Battery Capacity
A.1 Introduction
The Alpha FXM series UPS units run on batteries when the AC utility power fails. In this mode, the user may want
to estimate the remaining time that UPS batteries can supply power to the loads.
The battery run time remaining is calculated based on the Peukert equation. Two critical parameters are required
for the equation:
• Peukert number.
• Peukert capacity.
The Peukert number and Peukert capacity depend on the battery characteristics. This document describes the
procedures to determine the Peukert number, and Peukert capacity for the selected battery.
Once the Peukert’s number and capacity are determined, enter these values in the GUI or web interface. The
FXM will report the remaining battery run time.
The Peukert’s equation and the remaining battery run time are estimates only. The actual run time may vary
based on various parameters like the age and status of the batteries etc.
A.2 Determining the Peukert’s Number and Peukert’s Capacity
1. Obtain the data sheet of the selected battery.
2. Calculate the nominal load current for the application.
Example: If the load is 150 W and the battery string is 24 Vdc, the load current is calculated as 150 W / 24 V
= 6.25 A.
3. Find the current discharge ratings table in the data sheet. From the table, pick two current discharge values
(I1 and I2) that are closest to the calculated load current and look up the two discharge hours (R1 and R2).
4. Use the following formula to calculate Peukert's number and capacity:
Peukert’s number = n =
(Log (I
Peukert’s capacity = (I1)n x R
Log (R
per battery
1
)
2/R1
) - Log (I2))

A.3 Determining Peukert’s Capacity for Series Parallel Combinations
1. For batteries connected in series, the Peukert’s capacity for the battery bank is given by the equation:
Peukert’s capacity
2. For batteries connected in parallel, the Peukert’s capacity for the battery bank is given by the equation:
Battery bank
= Peukert’s capacity

The following example shows how to calculate Peukert’s number and capacity from a configured battery string.
Consider four Alpha 195GXL batteries connected and configured as shown in the figure below. Two of the four
batteries are connected in series, and the two series strings are connected in parallel to the 24 V DC output.

The Peukert’s number and capacity for the above configuration can be determined as follows:
1. Obtain the data sheet of the selected battery. See table below.
2. Find the current discharge ratings table in the data sheet. From the table, pick two current discharge values
(I1 and I2) that are closest to the calculated load current value. Look up the two discharge hours (R1 and R2).
3. From the table, I1 = 15.2A, I2 = 12A, R1 = 6 hrs, R2 = 8 hrs.
From Equation (1) earlier:
From Equation (2) earlier
4. The Peukert’s capacity for the series combination (Batteries #1 and #2) is 166.00 Ah.
5. The Peukert’s capacity for the parallel combination (Batteries #1, #2 and #3, #4) is 2 x 166.00 Ah = 332.00
Ah.

Appendix B - Types of Triggers
There are 3 types of trigger:
B.1 Edge trigger
When the user input changes from one state to the other, the Alpha FXM is triggered to perform Action #1. If the
level is set to High, the action will be triggered by a Low to High edge (leading edge). If the level is set to Low, the
action will be triggered by the High to Low edge (falling edge).
Action #1 Action #1

User Input = Low to High, Action #1 is triggered
User Input = High to Low, no action triggered

(b) Level = Low
User Input = High to Low, Action #1 is triggered
User Input = Low to High, no action triggered

Action #1 Action #1
Figure 59 — Edge Trigger
B.2 Level Toggle
When the Level is set to High, the Alpha FXM is triggered to perform the other action when the user input changes from Low to High. If the input then changes from High to Low, Action #2 will be triggered. In other words, a
level change in the user input will trigger an action toggle between Action #1 and #2.
Action #1 Action #1

Level Alternative
When the level is set to High, the Alpha FXM is triggered to perform the next action when the user input changes
from Low to High. If the input then changes from High to Low, no action will be triggered because the level is set
to High. In other words, only a Low to High user input level triggers an action when Level is set to High. Similarly,
when Level is set to Low, the Alpha FXM will trigger an action only with a High to Low user input.
