3. Site Planning

WARNING!

Restricted Access: The Alpha FXM350 and Micro350 must be installed in a restricted area accessible only by qualied 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 qualied 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 certied 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 (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 the Alpha 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 to accept 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.

6.2.3 St andby Mode

The FXM350 displays STANDBY when the DC breaker is closed (unit is ON), but no AC is present. When the AC input circuit breaker is switched on and line power is qualiﬁed, the Alpha FXM switches to LINE mode. If AC is within speciﬁcations, the FXM provides automatic voltage regulation (AVR).

6.2.4 Shutdown Mode

The FXM/Micro350 can be shut down by switching off the AC breaker and the DC breaker.

The unit can also be shut down from the front panel LCD or remotely through the USB and SNMP.

If the Shutdown command is applied in Back Up mode, the unit shuts the inverter and opens the grid relay (Figure 26).

If in Line mode, the grid relay is opened and the inverter disabled.

The FXM350 can be removed from Shutdown mode by manually resetting the AC and DC breakers or from the LCD or the web pages.

6.2.5 Fault Mode

If a fault occurs on the FXM (red LED solidly illuminated), the unit goes into Shutdown mode until the fault is cleared and reset. See Table P for a list of faults and to clear the fault, see Figure 28.

017-241-B0 Rev B

7. Operating the FXM350

7.1 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.

7.1.1 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.

7.1.2 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 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 page

43). 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 and adjusts 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. 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.

017-241-B0 Rev B

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

Procedure

1. 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.

017-241-B0 Rev B

7.2 Operating from the Control Panel Interface

The LCD control panel provides “at a glance” monitoring. This panel, when used along with the CANCEL, SCROLL and SELECT buttons, allows you to program, make measurements, and troubleshoot the Alpha

FXM350. Figure 27 shows the layout.

You can also put the Alpha FXM into this mode during initial startup in the absence of line power or because of unqualied line power. See #31Inverter On/Off in Table I.

One of the dry contacts of the FXM350 can be programmed to operate as a control for external DC disconnect and reconnect. (See LVD setting under "7.5.4 Programming the Dry Contacts" on page 82). The dry contact is energized when the battery voltage is greater than the DC Connect set voltage and will de-energize if the battery voltage drops below 42V for 48V system (21V for 24V system). The default reconnect voltage is set to 48VDC and can be adjusted up to 51VDC.

This function can be enabled only when the Alpha FXM is in Line mode. When enabled, the FXM locks into Line mode (no AVR) and disables the battery charger. This mode is used when maintaining batteries. OR Allows the use of a break-before-make manual bypass switch so the Alpha FXM can be shut off for maintenance without interrupting power to the load.

7.3.4.4 UPS M aintenance > 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 not confuse 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 at least 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 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.

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.

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 41 — 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.

017-241-B0 Rev B

Figure 42 — Time Of Day Action Operation

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 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 44). The dry contact will be activated by the timer regardless of the peak period settings.

Controlling the external fan with a temperature trigg ered 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.

7.3.9 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.

017-241-B0 Rev B

7.3.9.1 Keep Alive status/manual control:

a. The Status ﬁeld allows the user to enable or disable the Keep Alive function. (When disabled, the

alarm is cleared.) When the function is On, the Current column displays the status:

• Startup Delay

• Pinging

• Ping Echo Received

• Timeout total_number_of_retries/current_retry_number

• Reset total_number_of_retries/current_retry_number

• Reset Complete

• Failure

• Failure: Startup Delay

• Failure: Pinging

b. The Delay to Startup ﬁeld allows the user to set the time to the ﬁrst ping from the enable ping or

UPS restart after a ping failure. Minimum = 5 sec, Maximum = 3600 sec.

7.3.9.2 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.

7.3.9.3 H ow to detect communication failure:

a. In the Timeout ﬁeld, enter the ping timeout. Minimum = 2 sec, Maximum = 65535 sec.

b. In the Retries Before Failur e ﬁeld, enter the number of pings to repeat before power cycling.

Minimum = 1, Maximum = 20.

7.3.9.4 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. DC reset occurs when one drycontact is set to LVD.

b. The Action Duration ﬁeld is how long the output will be shut off by the UPS, Minimum = 5 sec,

Maximum = 3600 sec.

7.3.9.5 When To Fail:

a. The After X Consecu tive 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.

7.3.9.6 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 s, Maximum = 3600 s.

8.2 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 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.

8.2.3 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.

8.2.4 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 (77°F). 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 N — 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

8.2.5 Re placing 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

• 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”).

017-241-B0 Rev B

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.

8.2.5.2 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:

• From the Alpha FXM control panel, navigate to the UPS Control Menu > INV 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.

• From the Alpha UPS Monitor main screen, go to the UPS Maintenance > Unit Conﬁg uration 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.

017-241-B0 Rev B

8.3 Preventive Maintenance

Perform preventive maintenance on the Alpha FXM module every 6 to 12 months. For mission critical applications such as backup for 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.

8.3.1 Tools and Materials Required

• Wrench set

• Labels and marker to number batteries

• Conductance meter for optional conductance test

8.3.2 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.

8.3.3 Battery 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 2 V 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.
