1.2 General Warnings and Cautions
You must read and understand the following warnings before installing the Alpha Micro Secure 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 Micro Secure 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 Micro Secure’s 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 12Vdc.
• 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).

This starts the battery test and sets how long the test will run. The default setting for the
test duration is 2 minutes, but this can be adjusted in 1 minute intervals. See "Operating
the Alpha Micro Secure, BATT TEST”.
This switches the inverter on or off to allow you to prevent a damaging deep battery
discharge or to provide backup battery power to the load. See “Operating the
Alpha Micro Secure INVERTER”.
You can 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 Micro Secure 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
Battery modes. Once the Alpha Micro Secure returns to the Line mode, the delay resets
itself to 0 seconds.
This changes the Alpha Micro Secure’s password. The factory set password is 1111,
which can only be changed when the Alpha Micro Secure is in Line mode. The password
is limited to 4 alpha-numeric characters in length.
This lets you set the delay when the Alpha Micro Secure goes from Battery mode to
Line mode after the line becomes requalified. The purpose of this delay is to make sure
the line is stable before the Alpha Micro Secure switches back to it. See “Operating the
Alpha Micro Secure, QUAL TIME”.
The default setting is 3 seconds, but you can set this to 3, 10, 20, 30, 40 or 50 seconds.
The lets you set the Alpha Micro Secure’s low battery warning voltage, adjusting the
setting to match the batteries you are using and the actual operating conditions.
The default value is 40% (47 Vdc) and can be adjusted in 1% (0.05 Vdc) increments
between 45.0 (0 %) and 50.0 Vdc (100%) by typing in the % battery voltage level where
you want the warning to be triggered.

6.4.5 Programming the Dry Contacts and the Clock
On the Alpha Micro Secure front panel. contacts (C1 to C6) can be programmed to meet your specifications with
RS–232 communications. You can also adjust the Alpha Micro Secure date and time.
Programming the Dry Contacts
The functions of dry contacts C1 to C5 (and if factory configured, dry contact C6) can be changed with RS-232
communications.
For example, to change contact C1:
1. To see how it is currently programmed, type c1 (all lower case) and press Enter.
2. The Alpha Micro Secure responds with *c1=1 where the * shows the unit responded to your command.
For example: a "1" shows it is programmed to be the On Battery indicator as shown in the Dry Contact
Configuration table below.
Table I — Dry Contact Conguration
1= On Battery 4= Alarm 7= Timer 2
2= Low Battery 5= Fault 8= Timer 3
3= Timer 1 6= Disabled
3. To change the contact, type c1=X where X is 1 to 8 and press Enter.
The Alpha Micro Secure responds with *c1=(1 to 8). The programming is done for that contact. Repeat as
necessary for the other contacts.
Each contact can only be programmed for one function at a time and cannot show multiple conditions.
4. To reset the contacts to the factory default, type default and press Enter. The Alpha Micro Secure responds
with *default, showing it is reset. This command also resets the timer setting to the 2 hours factory default.
See “Setting the Timer Contact”. See "9. Specifications" on page 68 for the factory default settings of dry
contacts C1 to C6.

An accurate battery runtime estimation requires the following parameter to be adjusted:
• Peukert Number: Refer to the appendix for information about how to calculate the Peukert number to be
entered here.
• Battery Capacity: This is the rated capacity (Ah) of the battery shown on the battery data sheet. Do not con-
fuse 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 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.

Controlling the external fan by temperature triggered dry contact
The Alpha Micro Secure has up to 6 dry contacts (C1 to C6) on the front panel which can be configured by the
user to open or close based on the specific trigger conditions. Dry contact functions currently available include:
Alarm, Fault, Timer, Low Battery, On Battery, etc. The Temperature trigger has been added as a new function,
with a user configurable range of +20°C to +55°C. When the battery temperature (monitored by the Battery Temperature Probe) reaches the threshold, the assigned relay closes and turns on the external fan.
Dry contact C6 is by default factory hard wired to External Vdc. To configure C6 as a programmable dry contact,
the unit must be sent back to the factory.
The Temperature trigger can be programmed via one of the following 3 interfaces:
1. LCD panel – from the Logo screen, navigate to Control Menu > RELAY TEMP. Press the SELECT button
and the current temperature display will start flashing. Use the Scroll button to change the temperature in
5°C increments. Press SELECT to accept the changes or CANCEL to abort.

fails, the Alpha Micro Secure 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 fine during non rush hour traffic, but during rush hour, it may
be more desirable to keep the traffic light running normally for 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.
Figure 26 — Time Of Day Action Operation
You can define up to 2 peak time periods of the day:
1. Go to the UPS Maintenance > Relay & Load Shed screen.
2. 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).
3. Select ON under each time period. Click the Update button under each time period to store the settings.
Confirm your settings in the UPS Monitoring > Relay & Load Shed > Time of Day Action Status screen.

6.6.3 Types of Trigger
There are 3 types of trigger:
Edge trigger
When the user input changes from one state to the other, the Alpha Micro Secure 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).

Level Toggle
When the Level is set to High, the Alpha Micro Secure 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 Micro Secure 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 Micro Secure will trigger an action only with a High to Low
user input.

7.3 Testing and Replacing the Batteries
7.3.1 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 Micro Secure 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.
7.3.2 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.

Page 66
7.3.3 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.
7.3.4 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 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
7.3.5 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”).

7.4 Preventative Maintenance
Perform preventative maintenance on the Alpha Micro Secure 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.
7.4.1 Tools and Materials Required
• Wrench set.
• Labels and marker to number batteries.
• Conductance meter for optional conductance test.
7.4.2 Procedure
1. Inspect the Alpha Micro Secure 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 Micro Secure is connected
to Battery #1, and the battery positive cable from the Alpha Micro Secure is connected to Battery #4.
7. Verify that the battery temperature probe is securely taped to the side of either battery #2 or #3.
7.4.3 Operational Test
1. Activate the Alpha Micro Secure self-test function.
2. After passing the self-test, disconnect the AC input to the Alpha Micro Secure to trigger the unit into the
backup (Inverter) mode.
3. Let the Alpha Micro Secure operate in the backup mode for approximately 10 minutes.
4. Measure the individual battery voltages while the Alpha Micro Secure 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.

10. Peukert Number and Battery Capacity
10.1 Introduction
The Alpha Micro Secure 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 number and capacity are determined, enter these values in the GUI or web interface. The
Alpha Micro Secure will report the remaining battery run time.
The Peukert 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.
10.2 Determining the Peukert Number and Peukert 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 24Vdc, the load current is calculated as 150W / 24V =

The following example shows how to calculate Peukert 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 24Vdc output.

The Peukert 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:
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.

11. 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 the customer to
the factory or other authorized location during the warranty period. There are limitations to this warranty 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 installation of 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 or equipment 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.
11.1 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 the following
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 that was not available (in
months). Battery warranty coverage is lost where the battery charge is not maintained for 6 months. Contact your
Alpha sales representative or the Technical Support team at the above number to understand your entitlements
under Battery Warranty.
