WARNING!
Restricted Access: The Alpha FXM350 and Micro350 must be installed in a restricted
area accessible only by qualified service personnel.
The Alpha FXM350 and Micro350 are intended for permanent AC connection only.
The Alpha FXM350 and Micro350 must be correctly grounded for proper operation.
Older facilities may have inadequate electrical grounding. Inspection must be performed
by a qualified 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 breakercertified 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 thecircuit 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 (CBN) 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 FXM350 and Micro350 and batteries on a surface that can support the total weight. See
Chapter "10. Specifications" on page 98.

•

The input wiring must reach a suitably grounded power outlet and the load wiring must reach theAlpha FXM350 and Micro350 output terminal blocks.

•

Place the Alpha FXM350 in a properly sheltered location or inside a weather-proof enclosure to protect
the electronics from water, dust and other possible contamination.

•

Backup Generator (If used)
In Generator mode, the Alpha FXM range of acceptable input frequency and voltage is expanded toaccept the fluctuations created by a generator. See "7.2.2 The LCD Control Menu" on page 45, Table B,
Sense Type.
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 Battery
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.

Battery Heater Mats

The FXM350 and Micro350 allow connection, on its front panel, of a battery heater mat without a thermostat(#14 in Figure 3). Maximum power of the battery heater mat for use with the FXM350 connector is 55W. The
FXM turns the heater mat on when the temperature measured by the battery temperature sensor senses atemperature < 5°C. It turns the heater mat off when the temperature raises to >15°C. For the Micro350XL orbigger systems needing more than one heater mat, it is recommended to use the heater mats with built inthermostat and daughter heater mats that can be daisy chained. These heater mats may be wired to the AC
in the terminal block on the distribution panel. Ensure that the input breaker is appropriately rated.

Switch on the battery circuit breaker. The LCD displays STANDBY and the fan turns on for about aminute. If the temperature is below –15ºC, the LCD display may not function. See Chapter 9.

2. Switch on the AC input circuit breaker. The Alpha FXM qualifies the line power. The LCD displays
RETRAN, then shows LINE, or BUCK or BOOST, depending on the line voltage. (See Table A on page43). The status LED illuminates.
3. If there is no line power, the Alpha FXM remains in 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
28 — LCD Menu Tree" on page 44).
The Alpha FXM uses auto-frequency detection. When it is first switched on, it senses the line frequency andadjusts its output frequency to match that of the input. The load should be receiving power, If not, perform
troubleshooting.

7.1.3

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 when in Line mode. Doing so effectively disconnects 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.

40

Switch off the input circuit breaker. The LCD shows INVERTER, the status LED starts flashing to showthat the Alpha FXM is running on backup battery power. Confirm that the load is receiving power.

Switching the Alpha FXM from Standby mode to Inverter mode

When AC is not present and the loads need AC Power, the Alpha FXM can be forced to output AC using
energy from the batteries. To force the inverter on, refer to the CONTROL MENU, shown in Figure 28, and
INVERTER in Table B.

7.1.5

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 theAlpha FXM back to the Line mode as soon as possible by closing the AC input circuit breaker.
Procedure1.

Switch on the AC input circuit breaker. The Alpha FXM qualifies the line power. The LCD displays
RETRAN, then shows LINE, or BUCK, or BOOST.(See Table A on page 43). The status LED illuminates
steadily.

If the Alpha FXM constantly switches between INVERTER and LINE modes because of frequent disturbances on the line, the Alpha FXM input parameters should be broadened from Normal to Generator. See Table B,
Sense Type. Also see the specifications: “Boost/Buck/Line Transfer Thresholds”.
In the Generator mode, the range of acceptable input frequency and voltage are expanded to accept fluctuations and disturbances as created by a generator.

UPS Maintenance > Battery: Allows adjustments of battery string voltage, charging
parameters, low battery warning setting, periodic self test time, and starts the self test.

Figure 38 — UPS Maintenance: Battery screen

An accurate battery runtime estimation requires adjustment of the following parameter:•

Peukert Number: Refer to Appendix A for calculation of the Peukert number to enter here.

•

Battery Capacity: This is the rated capacity (Ah) of the battery shown on the battery data sheet. Do notconfuse the battery capacity with the Peukert capacity.

•

Battery Open Circuit Voltage: This number is obtained from the battery data sheet. The battery data
sheet shows the value for a single battery, so for a 48 V system where 4 batteries are connected in series, this number must be multiplied by four.

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 atleast one battery discharge cycle 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 ofat 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 alsochange rapidly during the last 20% of the discharge time when the battery is almost drained.

CAUTION!
The battery runtime is only an estimation and must not be relied on for critical applications. The battery runtime remaining is applicable only in inverter/backup mode.

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 auser-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 lightrunning normally as long as backup power is available. To address this issue, a new feature called the Timeof Day Action has been added to deactivate the timer during a user defined time period up to twice eachday.

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 43 — 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 theInverter 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 44). 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 energizes. The relay de-energizes when the temperature drops 10°C (18°F) from the Set temperature.
This relay can be used to turn on the external fan. Figure 45 shows the Relay Configuration window under the
UPS Maintenance > Relay & Load Shed screen. As an example, to assign C1 as the Temperature trigger,
a. Select Temperature from the drop down menu.
b. Click Update Configuration and the current status updates momentarily.
c. Figure 46 shows the fan-on temperature threshold set at 55°C. To change this value, type thenew value in the Fan On Temperature box (or use the up/down arrow keys) and click Update
Configuration to update the current status display.

Maintenance > User Input

Two programmable user inputs are available as well as two optional user inputs. They can be user-configured
similar to the dry contact relays. Supported functions include: (a) Shutdown, (b) User Alarm and (c) Self Test.
Any user input can be configured to perform a certain action in response to different trigger types and logic
levels. For example, if you want the Alpha FXM to issue an intrusion alarm when the door is opened, youneed to wire the door with a switch that triggers a user input every time the door is opened. The following
procedure describes how User Input 1 can be configured as an intrusion alarm input.
Procedure1.

Select UPS Maintenance > User Input to display the User Input Configuration window.

2. In the Input 1 column, select the Type down arrow to display the 3 types of available triggers: Edge

Testing and Replacing the Batteries

8.2.1

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 (77°F), will reduce battery life. For
example, an average operating temperature of 27°C (81°F) 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.

8.2.2

Battery Run Time

The chart below shows typical run times (time to full discharge) for the standard batteries supplied with thisunit. These runtimes are for batteries in new and good condition. The run time performance will deteriorate
over time in a progressively decreasing curve.

8.2.3

Battery MaintenanceThe 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.

8.2.4
1.

Battery Conductance Test (Optional)
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 (77°F). When
this value drops to 550 Siemens or 50% of the new battery reference value, the battery capacity is suspectof 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.

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.

8.2.5.1 Tools and Materials Required•

Warranty

Alpha Technologies Ltd. warrants all equipment manufactured by it to be free from defects in parts and labor,
for a period of two years from the date of shipment from the factory. The warranty provides for repairing,
replacing or issuing credit (at Alpha’s discretion) for any equipment manufactured by it and returned by thecustomer to the factory or other authorized location during the warranty period. There are limitations to thiswarranty coverage. The warranty does not provide to the customer or other parties any remedies other than
the above. It does not provide coverage for any loss of profits, loss of use, costs for removal or installationof defective equipment, damages or consequential damages based upon equipment failure during or after
the warranty period. No other obligations are expressed or implied. Warranty also does not cover damage orequipment failure due to cause(s) external to the unit including, but not limited to, environmental conditions,water damage, power surges or any other external influence.
The customer is responsible for all shipping and handling charges. Where products are covered under warranty Alpha will pay the cost of shipping the repaired or replacement unit back to the customer.

1.1

Battery Warranty

Note that battery warranty terms and conditions vary by battery and by intended use. The most common
battery warranty provided by Alpha is a two year full replacement warranty with a pro-rated warranty for thefollowing three years. Pro rated warranty provides a credit applicable toward the purchase of new batteries
from Alpha. The credit is calculated as the purchase price multiplied by the percentage of the battery life thatwas not available (in months). Battery warranty coverage is lost where the battery charge is not maintainedfor 6 months. Contact your Alpha sales representative or the Technical Support team at the above number tounderstand your entitlements under Battery Warranty.

Appendix A - Puekert 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 (R1and R2).
4. Use the following formula to calculate Peukert's number and capacity:

Log (R2/R1)(Log (I1) - Log (I2))(1)

Peukert’s capacity = (I1)n x R1 per battery(2)

Peukert’s number = n =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 Battery bank = Peukert’s capacity per battery Ah(as calculated in equation (2))

2. For batteries connected in parallel, the Peukert’s capacity for the battery bank is given by the equation:

Peukert’s capacity Battery bank = Peukert’s capacity per battery x N Ah
(where N = number of batteries in parallel)

A.4 Example
The following example shows how to calculate Peukert’s number and capacity from a configured battery
string.
Consider four Alpha 180GXL batteries connected and configured as shown in the figure below. Two of thefour batteries are connected in series, and the two series strings are connected in parallel to the 24 V DC
output.

Figure 71 — Battery string example

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 = 13.9A, I2 = 10.8A, R1 = 6 hrs, R2 = 8 hrs.
From Equation (1) earlier:

Peukert’s number = n =Log (R2/R1)(Log (I1) - Log (I2))

4. The Peukert’s capacity for the series combination (Batteries #1 and #2) is 120.55 Ah.
5. The Peukert’s capacity for the parallel combination (Batteries #1, #2 and #3, #4) is 2 x 120.55 Ah =241.10 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 toLow, the action will be triggered by the High to Low edge (falling edge).
Action #1
User input

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

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

Level Alternative
When the level is set to High, the Alpha FXM is triggered to perform the next action when the user inputchanges 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.
