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.
Page 4 to 95

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).
Never let live battery wires touch the Alpha FXM, the enclosure or any other metal objects. This can cause
a fire or explosion.
Never dispose of batteries in a fire. The batteries may explode. Follow the manufacturer’s directions and
check with your local jurisdictions for safe battery disposal.
Before attaching the batteries to the Alpha FXM, make sure that the polarity is correct.
If the batteries have been in storage for more than 3 months, recharge them for at least 24 hours and then
test them with a load before installation.
Each AlphaCell™ battery has a date code, found on the warning label, which must be recorded in the
maintenance log. If non-Alpha batteries are used, see the manufacturer’s documentation for date code type
and placement.

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
trouble- shooting.
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.
