1.2 General Warnings and Cautions
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.

• 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.

When Enable is selected and AC is lost, the FXM will be in Inverter mode. Turning
inverter on/off manually will work.
When inverter mode is set to ON, the Alpha FXM provides backup battery power
to the load. This mode of operation is normally activated automatically when line
power becomes unavailable, or the line power is not qualied. You can also put
the Alpha FXM into this mode during initial startup in the absence of line power or
because of unqualied line power.
This function can only be switched on when the Alpha FXM is in Line mode. When
switched on, it locks the Alpha FXM into the Line mode, switches off the battery
charger and makes the output voltage equal to the input voltage.
Used when:
• Replacing the batteries.
OR:
• To allow the use of a break-before-make manual bypass switch so the
Alpha FXM can be shut off for maintenance or replacement without interrupting

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.
OR:
Quality: Buck and boost modes are switched off; the input voltage is the Alpha FXM
output voltage.
Sets the Alpha FXM output voltage setting to one of the voltages specied in
"Specications" on page 80. Changing the voltage setting from factory default
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.
