TECHNICAL DESCRIPTION  
he Digital Technology-High Temperature  
CMN Series Continuous Power System (CPS)  
Reference the block diagram for a simplified  
explanation of the system’s operation. The AC utility  
source is connected to the power and micro  
electronics when the input switch is closed. The  
input line is filtered, power factor corrected and  
rectified for enhanced performance without  
disturbing other equipment that may share the same  
utility circuit.  
is a revolutionary new concept in total power  
protection and management. The CMN  
T
SERIES is a microprocessor-based UPS that now  
allows the user to set most of the control feature  
parameters. By directly linking a personal computer  
to the RS232 port, frequency settings and operation,  
alarm signals, load switching, etc. can all be  
programmed to meet specific application  
requirements.  
The microprocessor controls an Inverter Generator  
that produces a low harmonic, AC sinewave for  
continuous power applications.  
The CMN SERIES is a true on-line, continuous  
power UPS. In the tradition of Clary products, the  
CMN SERIES generates the same high quality and  
proven reliability to provide the best power  
When the input AC utility line fails, the battery circuit  
within this system takes over to ensure continuous  
power. Only until properly rated power is returned,  
does the microprocessor reconnect the input source  
back into the system.  
protection available for today’s critical applications.  
In keeping with state-of-the-art design, the power  
electronics are completely governed by an on-board  
microprocessor. Given the powerful memory  
capability of today’s micro controllers, this  
The microprocessor is directly tied to an external  
RS232 connector port. This allows the user to  
monitor and even set some of the operating  
parameters. With a simple link to a personal  
computer using the UPS software program, you can  
actually view, on your monitor, the event history of  
the power distribution system with the  
CMN SERIES unit as the central hub. More  
sophisticated users may implement the optional  
SNMP package to accomplish full Network Power  
Management.  
microprocessor has evolved the UPS into an all-in-  
one complete power distribution and monitoring  
center. Not only is your critical load insured of the  
most reliable and constant power available, but the  
user may now continuously track status of the  
supply components that keep the entire system  
operational. Production downtime can now be  
virtually eliminated by knowing exactly what patterns  
the supply utility power maintains and by knowing  
exactly the condition and life expectancy of the  
battery reserve.

SUMMARY OF INDICATORS AND CONTROLS  
SYSTEM POWER SWITCH - The main control  
switch that engages utility power to the entire unit.  
By activating this switch it initializes normal  
operation. Input circuit breaker must be on.  
Alarm Silent/Test - A momentary push-button  
switch that controls two different functions  
depending on the mode of operation. In the normal  
mode of operation, if this switch is depressed and  
held in, the above indicator will blink. Once it stops  
blinking, the unit will perform an internal 1 to 2  
minute battery check. Once the test is completed, if  
the battery is below standards, the system will  
indicate that the battery needs replacing. The  
system will not run this battery test unless the  
battery is detected to be fully charged. During  
battery or abnormal operation, an audible alarm will  
accompany this mode. By depressing this switch,  
the adjacent indicator will blink. When it stops  
blinking, the alarm will be silenced. Once the fault or  
reason for the alarm is corrected, this audible alarm  
condition will automatically reset. The audible alarm  
can be re-enabled during abnormal conditions by  
pressing and holding the switch again.  
AC In - The utility input indicator that identifies  
status of the line voltage. If the line voltage is within  
the specified range, it will remain lit. If the AC input  
is out of range, this indicator will flash in 1 to 2  
second intervals.  
Inverter - This indicator identifies the status of the  
regenerated, conditioned protected output power.  
This indicator will stay ON as long as protected  
power is available from the power inverter generator.  
Battery Level - This is the battery status bar graph.  
During normal operation, this bar graph will show the  
charging of the battery; all indicators lit will represent  
a fully charged battery. During battery operation,  
this bar graph represents a discharge meter  
indicating less battery time available as each L.E.D.  
turns OFF.  
NOTE - All switches must be held in for at least two  
seconds to engage their function. This is to prevent  
any inadvertent switch operation.  
Load Level - This is the system output capacity  
status bar. The number of L.E.D.s on the graph  
indicate an approximate percentage of system full  
load. All lights being ON would indicate full load.  
Alarm - This is a fault indicator that will light in the  
event that the inverter generator is non-operable.  
This could be due to an “over-temperature” situation  
or an inverter malfunction.  
DC INPUT - The battery input connector to add  
batteries.  
Cold Start - A momentary push-button switch to  
activate the system in the event no utility power is  
present. The system will be allowed to start up by  
using power from its batteries. Turn on the System  
Power Switch. Press and hold the Cold Start Switch  
until the audible alarm beeps once. Press and hold  
the LOAD I or II switch. The system will maintain a  
load depending upon the condition of the battery.  
120VAC OUTPUT (Load I & Load II) - The output  
groupings that can be independently controlled by  
the corresponding front panel switch. During normal  
operation, inverter generator power is supplied at  
these outlets.  
Load I and Load II - A momentary push-button  
switch that toggles the output LOAD I or II AC output  
outlets at the rear panel “ON /OFF”. The indicator  
above the switch will be ON to represent that LOAD I  
OR II Is activated. The output can be turned OFF by  
pressing and holding the switch. While the switch is  
depressed, the indicator will blink to represent  
transition. Once the indicator stops blinking, the  
switch can be released for a successful transition.  
SIGNAL - A DB-9 subminiature, female connector  
that outputs the open collector signal contacts for  
utility interrupt, low battery and inverter active  
conditions.  
RS232 - A DB-9 subminiature, female connector that  
outputs true RS232 communications signals.  
COOLING FAN - The cooling device necessary to  
maintain operation without defect. This cooling fan  
draws air directly across the internal heatsink.  
IDENTIFICATION LABEL - The model number and  
serial number of the system is located here. Always  
refer to this information when corresponding with the  
factory.

INSTALLATION  
he CMN Series unit is designed for installation  
The air should remain free from excessive dust  
in a protected environment. Units may be  
installed in a 19" rack system. The system is  
lightweight and can be easily moved. Some  
and chemical fumes.  
T
The front panel is designed to fit in a standard 19"  
rack. This panel fills a 5 ¼” slot. Guide Rails or  
slides are recommended to support the unit's  
mainframe. This system weighs in excess of 85  
pounds; front panel mounting is not intended to  
support the entire unit. The system has pre-tapped  
aluminum slide bars available to accept some  
standard slide configurations. Contact the factory  
for optional slide kits and accessories if assistance  
is required in properly mounting in a rack.  
important points to consider when positioning a unit  
for operation:  
A properly rated (preferably dedicated) outlet is  
accessible for the power cord supplied with the unit.  
It is not recommended to modify the supplied cord in  
any way nor should an extension cord of any kind be  
used.  
The cord paths in the system installation should  
remain clear of foot traffic or anything else that may  
disturb permanent connection.  
Once a location has been selected and the external  
battery pack is connected, it is ready for operation.  
Allow at least 48 hours, after the system is first  
installed, to fully charge the external battery to a  
maximum state. Charge time depends on the size  
of batteries used.  
The installation site should maintain an ambient air  
temperature of less than 40oC. 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.  
OPTIONS  
This rackmountable UPS is supplied with a matching rackmountable auxiliary battery box. This battery box is  
designed to host one or two strings of batteries, to extend battery support times. The additional time is dependent  
on the unit capacity and load size.  
The battery pack is rated at 96VDC and comes with a mating cable that directly connects to the battery port at the  
rear of the UPS. This connector is exposed, after removing the attached cover plate. The connector on the  
battery and UPS are the same so that the cable can be plugged in either way. The connector used is a locking  
type, when fully engaged, will not allow the cable to be pulled apart, unless the locking ears are depressed.  
The battery box fits a 3 1/2” slot into a 19” rack, just like the UPS. The full depth of the battery, however, is only  
23”. It is slide ready and weighs approximately 48 pounds in a single battery configuration. It weighs 85 pounds  
in a dual battery configuration. An additional port is available at the rear of the battery box to add continuous  
battery strings if necessary.  
The battery box is designed to be upgradeable. If the single string is not adequate, the user may order an  
additional string of batteries that can be easily installed in the existing box. By removing the existing mounting  
screws on the existing battery, it can slide over and the additional set can now be secured, with four additional  
screws, adjacent to the original set. The internal harness has an open connector provided for the second set.  
After plugging this connector together, the upgrade is complete.

how to start-up with no AC power available.  
The unit will start up similarly to normal AC start-up  
except the AC IN L.E.D. will continue to flash. The  
LOAD outputs will come up in the OFF mode when  
using the COLD START feature. You must press and  
hold the LOAD I or LOAD II switch to activate the  
inverter.  
Normal Operation on AC Start-Up:  
Verify that the unit is plugged into properly rated  
electrical power.  
Connect Cable from Aux. Battery Box to UPS.  
Position the Input Circuit Breaker to the ON  
position.  
Loading the System  
The system can be loaded up to full rated load. As  
load is applied, the LOAD METER will start to turn  
ON. The LOAD METER will not work when you are in  
a “Manual Bypass”. Once full load is achieved, the  
full LOAD METER should be lit. As additional load is  
applied, the top red OVERLOAD L.E.D. will come ON.  
If too much overload is applied, the audible alarm will  
sound. If this increased load is not removed within  
five seconds, the unit will discontinue output  
operation and latch into an alarm condition. The  
audible alarm will continue to sound and the ALARM  
L.E.D. will light. Reducing the load and cycling the  
System Power Switch OFF then ON can reset the  
system.  
Position the System Power Switch to the ON  
position and the BYPASS SWITCH to the INV  
position. You will now have Bypass power at the  
receptacles.  
The system will proceed through about a three  
second diagnostic where all the L.E.D.s will sequence  
ON then OFF. The AC IN L.E.D. will flash several  
times and the audible alarm will give a short burst.  
The AC IN light L.E.D. will then stay ON and the  
battery level meter will light to at least an 80% level.  
The INVERTER L.E.D. will come ON and inverter  
power will now be available at all the output  
receptacles. The LOAD I and LOAD II will come ON.  
Actual load may be connected at any time during this  
procedure, however inverter power is only available  
when the L.E.D. above either of the LOAD switches is  
ON continuously.  
Programming the Outputs:  
The outputs on startup can be programmed ON or  
OFF. The default mode is programmed to turn both  
load circuits ON whenever you power up the UPS on  
AC startup. They will stay energized until you turn  
OFF the UPS, the batteries run down during a power  
outage or if the appropriate load button is pressed.  
Battery Operation after AC Start-Up:  
Unplug the unit from the standard wall outlet.  
The AC In L.E.D. will flash at two to three second  
intervals. Within 5 seconds, the audible alarm will  
sound at half-second intervals.  
To program both loads to be OFF when the UPS is  
turned ON:  
Push and hold in the ALARM SILENT/TEST  
switch until the audible alarm is inhibited.  
Turn the UPS OFF.  
Turn the UPS ON while pressing and holding the  
LOAD I OR II switch.  
If operation were to continue in this mode, the  
BATTERY LEVEL meter would start to turn OFF, one  
L.E.D. at a time starting from the top. Once the last  
L.E.D. is left, the alarm will sound in a constant tone.  
Had the alarm been previously silenced, it would still  
re-enable to alert the user of limited operation. This  
alarm can also be silenced as before. If the unit is  
allowed to operate further, it will time shut off the  
loads. If power were to return, the unit will  
The UPS will come ON with both loads OFF and  
will remember this setting each time the unit is  
turned ON.  
To program both loads to come ON:  
Turn the UPS OFF.  
Turn the UPS ON while pressing and holding both  
LOAD I and LOAD II switches (this definitely  
requires both hands). The UPS will remember  
this combination the next time it is powered ON.  
automatically restart and return to the condition it was  
in at the moment it went into Battery Mode.

SIGNALS AND INTERFACING  
t the rear of the unit are two DB-9,  
subminiature, female connectors. These are  
provided for communications links to a  
computer or sophisticated monitoring device.  
This conserves the battery life once an orderly  
shutdown has been accomplished. The system may  
be configured to shutdown by simply shorting pins 6  
and 7. Contact the factory for configuration details.  
A
SIGNAL PORT DB-9 provides open collector type  
closures that typically signal Utility Interrupt, Low  
Battery and Inverter Active conditions. A system  
shutdown feature is also available on this port.  
Applying a +5-12V signal across the appropriate  
pins will cause the system to shutdown in battery  
mode.  
RS232 DB-9 is a true RS232 communications signal  
port. On rackmount units, this port is on a  
removable plate, which can be substituted with an  
optional SNMP card. Below is the pin out of the two
