THE CMN SERIES RACKMOUNT
A digital on-line, sinewave UPS is the only total solution to virtually any power problem. It effectively
provides CONTINUOUS POWER, by regenerating the incoming AC to DC and then back to a highly
regulated AC. A battery is provided at the input of the AC Inverter to support the load in case of utility
interruption. The CONTINUOUS power concept is a step above the typical UPS, in that, power protection
is maintained under any circumstance for the most complete and reliable service to the critical load. This
CONTINUOUS power UPS is designed for the critical, must-not-fail applications.
The CMN Series rackmount is engineered with the latest Insulated Gate Bipolar Transistor/Pulse Width
Modulation (IGBT/PWM) technology for high efficiency and reliability. The electronics are completely
governed by an on-board microprocessor. This allows for not only a digitally processed precision output
waveform, but also provides for full interactive access and control for the user through an RS232
computer port.
Refer to the simplified block diagram, Figure 1, for system description. An AC source is fed through a
double pole breaker for both Hot and Neutral protection. This breaker then feeds the power circuits and
all internal microelectronics. Input voltage is monitored to allow for continuous operation over a -25% to
+35% range of nominal voltage for all load conditions. An input voltage variation outside the preset
window will transfer operation to battery energy without a shutdown.
The input AC, when within the specified window, is power factor corrected and then sent to the
rectification stage. The DC rectifier stage provides both positive and negative voltages to a DC rail stage,
which then feeds the digitally controlled inverter AC. The AC inverter supplies the load and supports the
battery charger as long as input utility is available. Normally the output inverter is at 60Hz independent of
the input line frequency. The output inverter is synchronized to the utility line frequency.
During a utility power-loss, the AC rectification and battery charging capabilities of the UPS become
inactive. The fully charged battery system now becomes the source of power feeding the AC Inverter
generator. All systems are controlled by the digital microprocessor at all times.
The CMN Series on-line topology is unique to other on-line systems in that it is designed to meet the
needs of all non-linear type loads while providing input power factor correction. Computers and
telecommunications equipment, with their switching power supplies are considered a non-linear load,
which can be very abusive to most power protection equipment and could decrease life expectancy. The
CMN Series is specially designed with a power factor corrected input to eliminate harmonics back into
the power source as well as accept non-linear loads and protect them efficiently without any output
waveform degradation common to other UPS designs.
If the unit is overloaded, it will shutdown completely if the overload is not corrected within 3 seconds.

SUMMARY OF INDICATORS AND CONTROLS
UPS FRONT PANEL
INPUT POWER SWITCH - This is system input AC power protection and interruption for both hot
and neutral lines. This is a circuit breaker that if tripped, unit operation will continue on battery reserve.
This circuit breaker is rated at 30A and is guarded to prevent inadvertent operation.
SYSTEM ON/OFF SWITCH - This is system input enable switch. This switch is used to power
down the system. This switch must be in the ON position in order to AC or DC start the UPS.
AC INPUT LED - A green L.E.D. that is illuminated when the INPUT POWER Circuit Breaker is closed
and there is AC input power available to the UPS.
LOAD LEDs - Four green L.E.D.s and one red OVERLOAD L.E.D. that illuminate to update status of
the amount of load the INVERTER is powering at the UPS system output. Each green L.E.D. represents
approximately 25% of full load. As more load is added to the UPS, the L.E.D.s will sequentially turn "ON"
until the red L.E.D. comes "ON". This indicates an OVERLOAD situation and the system will discontinue
operation shortly.
BATTERY LEDs - Four green L.E.D.s and one green LOW BATTERY L.E.D. that illuminate to update
status of the battery energy available during a power outage. Each green L.E.D. represents
approximately 20% of battery reserve power available. As battery discharge continues, the L.E.D.s will
sequentially turn "OFF" until the last L.E.D. starts to flash. This indicates a LOW BATTERY situation and
the system will discontinue operation shortly. Once utility power is returned to the system, this bar graph
will show an approximate battery state as it reaches full charge. The top L.E.D. indicates charger on/off
when unit running on AC. L.E.D. ON Charger OFF, L.E.D. OFF Charger ON.
AC IN OK LED- A green L.E.D. that is illuminated when the AC input is within operating limits. Upon
startup of the UPS, good utility power is approx. 100Vac-130Vac. Once UPS is running, range would be
approx. 85Vac-155Vac.
ON BATTERY LED - A red L.E.D. that is illuminated when the AC input is interrupted to the power
electronics either externally or internally from the microprocessor due to an out-of-range situation. The
output load is then supported entirely by battery energy through INVERTER operation.
AC OUTPUT LED - A green L.E.D. that illuminates when the INVERTER generator is operating and
available to deliver power to the system output.
COLD START SWITCH - This is a momentary, push button switch. If no AC utility voltage is
available, it may still be a requirement to initialize some equipment. When this switch is pressed in for at
least two seconds, the system will start up on battery power. The SYSTEM ON/OFF Switch on the Front
Panel of the unit and the POWER Switch on the Control Panel must be in the ON position for this function
to operate. The green L.E.D. above this switch will light only while the switch is held in.
COLD START LED - A green L.E.D. that illuminates when the cold start switch is pressed.
LOAD ON/OFF SWITCH - Push button switch that enables output circuits when turned ON, disables
output circuits when turned OFF.
BYPASS LED - A red L.E.D. above the LOAD ON/OFF SWITCH will light to indicate when the system
output is operating in the filtered, emergency BYPASS mode. This is an unprotected power source that
will not support the load in the event of a power failure.
Page 10
BATTERY TEST SWITCH - This is a momentary, push button switch. Battery condition is vital to
the UPS performance, particularly during a power outage. During normal operation with inverter ON, load
applied to the unit and the Battery Bar Graph showing the battery at a full charge, this function switch
may be used. By pressing this switch in for at least two seconds, a battery acceptance diagnostic will be
run by the internal microprocessor. During the battery test, the Replace L.E.D. will flash and the On Batt
L.E.D. will be it. The test will run for approx. 30 seconds.
REPLACE BATTERY LED – After the battery acceptance diagnostic test has discovered that the
batteries are excessively fatigued, the amber L.E.D. above this switch will light advising the user that the
Batteries are bad and should be replaced or battery module is not connected to the UPS.
ALARM RESET SWITCH - This is a momentary, push button switch. During a system FAULT or
power failure, an audible alarm will be present. Once this switch is pressed in for at least two seconds,
the audible alarm will be silenced. The L.E.D. above the switch will remain unchanged. Additional Alarm
conditions will re-annunciate the alarm, which then can be silenced again.
FAULT LED - If a FAULT condition occurs, this red L.E.D. will illuminate.
UPS REAR PANEL
INTERFACE - One CPC Type, 37 position reversed sex connectors provided for critical loads.
Continuous power is provided here and is monitored by the LOAD L.E.D.s as long as the INVERTER is
functioning. The Loads ON/OFF Switch must be enabled for power to be present here. 120VAC Fan
Power, Fan sensor and Temp sensors are also provided.
RS232 CONNECTOR - DB-9 subminiature female connectors provided for intelligent computer
monitoring systems. See SIGNALS AND INTERFACING Section for specific pin-outs.
CONTROL PANEL CONNECTOR - DB-25 subminiature female connectors provided for
interfacing the control panel. See SIGNALS AND INTERFACING Section for specific pin-outs.
INPUT – One CPC Type, 3 position inlet connector for AC input.
GROUND - A 10-32 x 3/4 threaded stud for system rack grounding.
SNMP INTERFACE - (OPTIONAL) An add-on card that provides Simple Network Management
Protocol (SNMP) access to the UPS controller via a RJ45 connector (LAN). The second RJ45 connector
(RS232) provides a second RS232 port to the controller.

INSTALLATION
This Rackmount system is designed for installation in a protected environment. This system may
be installed in a 19" rack system. Some important points to consider when positioning a unit for
operation:
• A 30A (preferably dedicated) outlet is accessible for the power connection to the unit. It
is not recommended to modify the power cord in any way nor should an extension cord
of any kind be used. Never use a surge protected device on the output of this
system.
• The cord paths in the system installation should remain clear of foot traffic or anything
else that may disturb permanent connection.
• The installation site should maintain an ambient air temperature of less than 140oF
(60oC). When the environment for the system remains cooler during operation, there is
less stress on the batteries and the internal electronics.
• The air inlets, vents and fan should not be obstructed or blocked in any way. The more
breathing space the system has, the cooler it operates.
• The air should remain free from excessive dust and chemical fumes.
• The front panel is designed to fit in a standard 19" rack. This panel fills a 5.25 inch (3U)
slot. Guide Rails or slides are recommended to support the unit's mainframe. This
system weighs in access of 100 pounds. The front panel mounting screws are not
intended to support the entire unit. The system comes with pre-tapped slide mounting
holes.
Once a location has been selected and the unit is installed, it is ready for operation.
FIGURE 6:
Page 15
OPERATION
⇒ Plug in the Control Panel (UPS Connector) with a male to female DB25 cable to the DB25
“Control Panel” Connector on the back of the unit.
⇒ Be sure the power cord is plugged into an appropriately rated outlet.
⇒ Activate the INPUT ON/OFF Circuit Breaker to the “ON” position on the UPS.
⇒ The AC INPUT L.E.D. will illuminate.
⇒ Activate the UPS Front Panel SYSTEM ON/OFF Switch to the “ON” position. Activate the
Control Panel POWER ON switch to the “ON” position. Both switches must be “ON” to turn
on the unit.
⇒ The system will go through a diagnostic test routine.
⇒ The green AC IN OK L.E.D. will flash several times before it illuminates solid.
⇒ Green BATTERY L.E.D.s will illuminate.
⇒ The audible alarm will sound a short burst.
⇒ Push and hold in the LOAD ON/OFF Switch for at least two seconds. You can use either
Load ON/OFF Switch from the UPS or the Control Panel.
⇒ On the UPS, the AC OUTPUT L.E.D. will illuminate. On the Control Panel, you will see the
AC OUTPUT L.E.D. illuminate and the loads 1-8 will illuminate in a sequence (if Load switches
are in the “ON” position).
Switch the INPUT ON/OFF Circuit Breaker “OFF”. This will simulate a power loss to test battery
operation.
⇒ The green AC IN OK L.E.D. will flash every two to three seconds. On the Control Panel, the
ON BATT L.E.D. will illuminate and the ON AC L.E.D. will turn off.
⇒ The red ON BATT L.E.D. illuminates on the UPS.
⇒ An intermittent audible alarm will sound. (The ALARM RESET Switch may be operated at
this time, it must be held in for at least 2 seconds to silence the alarm.)
⇒ As battery discharge continues in this condition, the five green BATTERY L.E.D.s will start to
shut off. Each led represents approximately 20% of the battery reserve available. If this
were to continue until all four L.E.D.s shut off, the last green L.E.D. will flash, indicating that a
LOW BATTERY situation is present and system shutdown is imminent. The LOW BATT
L.E.D. on the Control Panel and the UPS will illuminate. The intermittent audible alarm will
become continuous at this point. The UPS will automatically shut itself off to avoid excessive
battery discharge. When power returns, normal operation of the UPS resumes without any
operator interaction.
1. The duration of actual battery backup time and the LOW BATTERY condition varies
depending on the amount of load, charge on the battery, and condition of the battery.
To check the battery;
⇒ Push and hold the TEST switch in for at least two seconds.
Page 16
⇒ The amber REPLACE BATT L.E.D. will flash and the audible alarm will sound.
The microprocessor will run a battery diagnostic check.
⇒ The Control Panel audible alarm will sound after the test.
If the battery is found to be fatigued compared to predetermined or typical battery parameters,
the amber REPLACE BATT L.E.D. will illuminate, suggesting the user replace the batteries. If
the SNMP battery test function is enabled, the microprocessor automatically runs this test. The
user will be alerted of a faulty battery or battery not connected to the UPS.
Activate the SYSTEM ON/OFF Switch to the “OFF” position to discontinue system operation.
Turn off the devices you wish to plug into the UPS. Connect them to the output at the rear of the
unit. Do not exceed the output ratings of the system.
⇒ Activate the SYSTEM ON/OFF Switch to the “ON” position.
⇒ The system will go through a diagnostic test routine and test all the L.E.D.s with the
exception of the COLD START L.E.D.
⇒ Push and hold in the LOAD ON/OFF Switch for at least two seconds.
⇒ The AC OUTPUT L.E.D. will illuminate indicating output power is available at the rear panel
outlets.
⇒ Turn “ON” the Load Switches on the Control Panel.
⇒ Turn “ON” each of your devices.
⇒ Some of the four green L.E.D. LOAD indicators should illuminate. The amount of load is
determined by the actual number of indicators lit.
Each L.E.D. signifies approximately 25% of load capacity. If all four L.E.D.s illuminate, full load
has been achieved. If the red light illuminates, an OVERLOAD condition is present. If this
situation continues beyond three seconds, the unit will automatically shut off, discontinuing all
operation including the output to the load. The red FAULT L.E.D. will light and a continuous
alarm will be heard. The load must be reduced and the SYSTEM ON/OFF Switch will have to be
reset in order to return to normal operation.
If the system overheats or the INVERTER should fail, the unit automatically transfers power to
the BYPASS line to maintain uninterrupted power to the load. The red BYPASS L.E.D., above
the LOAD ON/OFF Switch, will light. A continuous alarm will sound and the red FAULT L.E.D.
will illuminate.
To escape this condition, the problem must first be corrected, then the SYSTEM ON/OFF Switch
must be reset.
To DC Start the unit:
⇒ Activate the UPS Front Panel SYSTEM ON/OFF Switch to the “ON” position. Activate the
Control Panel POWER ON switch to the “ON” position.
⇒ Push and hold the COLD START switch on the UPS until the alarm sounds once.
⇒ Push and hold in the LOADS ON/OFF Switch for at least two seconds. You can use either
Loads ON/OFF switch from the UPS or the Control Panel.
Page 17

SIGNALS AND INTERFACING
This system is designed to be compatible with most sophisticated operating systems when they
feature a UPS monitoring function. These signals are made available through the DB-25
subminiature female connector at the rear of the Control Panel. Interfacing cables are available.
The communications connector at the rear of the UPS is for a RS232 interface connection. The
Remote Panel connector features open-collector alarm signals. Closing the points between pins
6 and 8 while running on battery will shutdown the UPS. Below is a diagram of the signal jacks
and their pin-outs:

CARE & MAINTENANCE
This system is designed to be maintenance-free. It can be cleaned with a damp cloth or nonabrasive cleanser.
Be sure filters and vents are kept free from accumulation of dust, dirt or lint.
If the unit is placed in storage, it is recommended that the battery be fully charged. Never allow
the battery to remain in a discharged state for an extended period of time. Also, when storing
units, the batteries should be recharged every 90 days. To recharge the batteries in a stored
unit, it must be plugged in and the inverter needs to be switched “ON”. Allow the system to charge
for at least 24 hours.
WARNING: Never attempt to service the batteries. High voltage exists within the unit, which
could cause electrical shock. Servicing of batteries should be performed or supervised by
personnel knowledgeable of batteries and the required precautions. Keep unauthorized
personnel away from the batteries.
WARNING: Only replace batteries with Clary part number 223-15176.
CAUTION- Do not replace the individual batteries in the battery pack.
CAUTION- Do not dispose of battery or batteries in a fire. The battery may explode.
CAUTION- Do not open or mutilate the battery or batteries. Released electrolyte is harmful to
the skin and eyes. It may be toxic.
CAUTION- A battery can present a risk of electrical shock and high short circuit current. The
following precautions should be observed when working on batteries.
1.
Remove watches, rings, or other metal objects.
2.
Use tools with insulated handles.
3.
Wear rubber gloves and boots.
4.
Do not lay tools or metal parts on top of batteries.
5.
Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
source of ground. Contact with any part of a grounded battery can result in electrical

BATTERY PACK INSTALLATION AND REPLACEMENT
REPLACING THE BATTERY PACK
Your new replacement Battery Pack (223-15176) was designed as a plug in, hot swap
battery pack that can be ordered separately.
CAUTION: Before removing the battery pack from your system, insure that you have a
replacement battery pack readily available.
Remove new battery pack from shipping box prior to uninstalling existing battery pack.
This packaging will aid in return or disposal of your old used batteries. Prior to removal
of existing battery pack insure that your UPS System is secured into a fixed position in a
rack or it is sitting flat on a work bench or other flat firm surface. Locate the six flat head
machine screws holding the battery pack into position. Remove existing battery pack
using the steps below. Upon sliding the battery pack out, it will hang up at the rear
before it comes out of the UPS. This will help you feel the weight of the battery pack
prior to full removal. Lift the battery pack a little and it can be safely removed. To install
new battery pack, repeat the steps below in reverse order.
CAUTION: The battery pack is heavy (48 pounds), handle with care not to damage rear
connectors.
1. Remove the six 10-32X1/2 screws from the front of the battery pack.
2. With one hand grab the front handle and slowly pull out about 8 inches.
3. Place other hand under battery pack for support and slowly pull all the way out.
