THE SP-MPL 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 generator. A battery can be provided at the input of the AC
generator to support the load in case of utility interruption. The CONTINUOUS power concept is
a step above the typical power conditioner, in that, power protection is maintained under any
circumstance for the most complete and reliable service to the critical load. This CONTINUOUS
power UPR is designed for the critical, must-not-fail

The Digital Technology (DT) Series rackmount is engineered with the latest Insulated Gate
Bipolar Transistor/Pulse Width Modulation (IGBT/PWM) technology for high efficiency and
reliability. The uninterruptible power system (UPS) is the ruggedized version of the DT family of
products. 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 operation
over a -25% to +35% range of nominal voltage for all load conditions. An input voltage variation
outside this preset window will discontinue power to the critical load.

The input AC, when it is within this 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 generator. The AC inverter
generator in turn supplies the load. Normally the output inverter generator is at 60Hz
independent of the input line frequency.

applications.

The DT 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 non­linear load, which can be very abusive to most power protection equipment and could decrease
life expectancy. The DT 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 UPR designs.

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 circuit breaker is rated at 20A.

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 start the UPR.

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.

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.

INVERTER LED - A green L.E.D. that illuminates when the INVERTER generator is operating.

COLD START SWITCH - This is a momentary, two position 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 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.

- A red L.E.D. above the LOAD ON/OFF SWITCH will light to indicate when the

BATTERY TEST SWITCH - This is a momentary, two position 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.

Page 8

REPLACE BATTERY LED - After the battery acceptance diagnostic test has discovered

that the batteries are excessively fatigued, the red 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. During battery test this LED will flash red for approx. 30 seconds.

ALARM RESET SWITCH - This is a momentary, two position 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.

FAULT LED - If a FAULT condition occurs, this red L.E.D. will illuminate.

LOAD SWITCHES AC1 - AC8 – Locking switches that turn on and off corresponding AC

outputs.

LOAD LEDS AC1 - AC8 – Green illumination indicates load is available at corresponding

outputs.

OVERRIDE SWITCH – When this locking switch is turned on, load switches (Loads 1-8) can

only be activated manually. You will not be allowed to control the load switches through the
SNMP with this switch activated.

OVERRIDE LED – Red illumination indicates override switch is turned on.

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 20A (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.

o

• The installation site should maintain an ambient air temperature of less than 140

o

C). When the environment for the system remains cooler during operation, there is

(60
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.

F

• 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 can weigh in access of 40 pounds, therefor front panel mounting is not intended
to support the entire unit. The system comes with pre-tapped aluminum slide bars to
accept Jonathan QD-145 slides. Separate shims are included for correct slide bar
spacing if the unit is installed in a DTC-2 (C3) rack.

Once a location has been selected and the unit is installed, it is ready for operation.

Once the unit is installed into a rack, small adjustments may be required for the front panel to
screw mount into the frame. Refer to the following steps and diagram to adjust the panel to the
desired position:

1) Loosen, but do not remove, all screws holding in the front panel.

2) Loosen, but do not remove, the four acorn nuts on the handles.

3) The entire front panel should now have limited play for exact positioning.

4) Install the four panel mounting screws in front panel slots into the rack enclosure.

5) Retighten all

screws and nuts that you have loosened.

OPERATION

 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.

 Activate the SYSTEM ON/OFF Switch to the “ON” position on the UPS.

 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.

 The audible alarm will sound a short burst.

 The AC INV L.E.D. will illuminate and the loads AC1-8 will illuminate.(if Load switches are in

the “ON” position).

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.

 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
must be reset.

The ALARM RESET Switch on the front panel of the UPS can be used at any time to silence the
audible alarm. This switch must be held in for at least two seconds before the alarm will quiet.
The FAULT L.E.D. above this switch will remain unchanged while operating this switch.

SYSTEM ON/OFF Switch

Page 12

Battery Operation after AC Start-Up:

Turn Off the Circuit Breaker on the Front Panel of the UPS.

The AC ON light will flash at two to three second intervals. Within 5 seconds, the audible alarm
will sound at half-second intervals.

Push and hold in the ALARM SILENT/TEST switch until the audible alarm is inhibited.

If operation were to continue in this mode, the battery level meter would start to turn OFF, one
light at a time starting from the top. Once the last light is left and the preprogrammed battery
availability time (usually about 2 minutes) is reached, 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 out and shut off completely. If power were to return, the unit will automatically restart
and return to the condition it was in at the moment it went into Battery Mode.

DC Start Operation (Cold Start)

If no utility power is available at the time backup power is required, the unit may be started to
accomplish abbreviated tasks. The limitations of the battery prevent extended operations at full
load.

Position the System Power Switch to the ON position.

Push and hold in the cold start switch until the audible alarm beeps.

The unit will start up similarly to normal AC start-up except the AC IN LED will continue to flash.
The LOAD outputs will come up in the off mode when using the cold start feature.

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-9
subminiature female connector at the rear of the UPS. The communications connector at the
rear of the UPR is for a RS232 interface connection. The Signal connector features open­collector 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:
