1. INTRODUCTION
1.1. GENERAL
The principles of operation described herein are applicable to all models. The DSPM, Inc. Three Phase Uninterruptible Power
Systems are manufactured to provide critical power for lighting during a power outage. The Three Phase Inverter meets or
exceeds the life safety codes of UL924 and UL1778. These codes were established to allow the Uninterruptible Power Sys-
tems to provide critical power to the lighting circuits during a power failure. The Uninterruptible Power System will then provide
power for 90 minutes that will allow safe and orderly evacuation from the facility.
The product is an advanced Uninterruptible Power System based on Intelligent Microprocessor Control. The Uninterruptible
Power System is an intelligent protector and provides pure, reliable AC power to the emergency loads – protecting them from
utility power blackouts, swells, sags, surges and interference. All types of lamps are supported by our lighting inverter.
Under normal power conditions, this design enables the system to adjust and lter power uctuations continuously and auto-
matically. In the event of a power failure, it can immediately provide back-up power from the batteries without any interruption.
When the utility power is connected or reconnected, the charger will automatically recharge the batteries.
When input power to the Three Phase Inverter is lost during a power outage, the system will automatically draw power from its
internal battery supply without any interruption. The critical load will receive only clean sine wave power. The internal VRLA
(valve regulated lead-acid), maintenance-free batteries provide 90 minutes of backup power.
Upon restoration of input power, the Three Phase Inverter automatically resumes normal operation, and immediately begins
to recharge the batteries. The Three Phase Inverter has an internal bypass circuit, which maintains the power to the load in
case of internal UPS failure.
The Advanced Battery Management system in this unit uses a Digital Signal Processing/Pulse-Width Modulation (DSP/PWM)
Smart Battery Monitoring System for managing the system batteries. The DSP/PWM Smart Battery Monitoring System is
temperature compensated resulting in maintaining maximum runtime and battery life. The microprocessor controls recharge
and the DSP/PWM offer overcharge protection.
The Three Phase Uninterruptible Power System incorporates double-conversion technology that provides perfect protection
specically for Egress Lighting for facilities. It is designed to provide continuous and clean electrical power to a critical load.
The load is powered by the inverter, which receives its power from the building source. In the event of an input power failure,
the UPS will supply power to the critical load for the specied battery time.
The inverter uses of a double-conversion principle eliminates all sources of unwanted power disturbances. A rectier converts
the alternating current from the building source to Direct Current (DC). This DC charges the batteries and powers the inverter.
With the basic DC voltage, the inverter generates a sinusoidal alternating current (AC) voltage, which continuously supplies
the load. In times of power outrages, the 90-minute backup time that come standard in our units keep the load energized.
If the input power is not restored promptly, backup power from the UPS battery permits the orderly shutdown of equipment
supported by the UPS. The UPS is simple to start up, operate and maintain.
The Three Phase Inverter is a PWM inverter available in output rating of 3—150 kVA. All models have external batteries
cabinet (s) in which the batteries are housed. It is listed for compliance to UL1778, UL924, UL924A and CSA107.1 standards.

Chapter 2 for a complete listing of the Three Phase Inverter specications. This manual provides an overview of the Three
Phase Inverter components and their functions. The appearance and purpose of operator controls and indicators is de-
scribed with procedures for operation, start-up, shutdown and basic maintenance included.
1.2.1. UNINTERRUPTIBLE POWER SUPPLY SYSTEM (UPS) - All components within the UPS Module Cabinet
and associated batteries, which function as a system to provide continuous, conditioned AC power to a load.
1.2.2. UPS MODULE CABINET - The metal enclosure which contains the Rectier / Charger, Inverter, Static Trans-
fer Switch, Internal Bypass line, operator controls, batteries (up to 30kVA models only) and internal control systems
required to provide specied AC power to a load.
1.2.3. UPS MODULE - The Rectier / Charger and Inverter assemblies which, under the direction of the internal
control system and operator controls, provide specied AC power to a load.
1.2.4. RECTIFIER / CHARGER - The UPS components which contain the equipment and controls necessary to
convert input AC power to regulated DC power required for battery charging and for supplying power to the Inverter.
1.2.5. INVERTER - The UPS components which contain the equipment and controls necessary to convert DC
power from the Rectier / Charger, or the battery, to AC power required by the critical load.
1.2.6. STATIC TRANSFER SWITCH - The device that connects the critical load to the bypass line when the Inverter
cannot supply continuous power.
1.2.7. BYPASS LINE - The line, which conducts electricity directly from the input power source to the critical load
during Maintenance or whenever the UPS is not completely operational.
1.2.8. AC INPUT POWER - Is the power provided by the electrical utility company, or auxiliary generator, which is
connected to the UPS for supplying the critical load and recharging the battery.
1.2.9. BATTERY - The rechargeable battery strings that supply DC power to the inverter to maintain continuous AC
power to the load during AC input power failure conditions.
1.2. DEFINITIONS
1.3.1. Manual Bypass Mode
Applying Utility power to the input with the Bypass switch in its Manual/BPS position will place the unit into its Man-
ual Bypass Mode. The battery charger is activated allowing the batteries to charge. The control boards will pow-
er-up, but the inverter will not turn on. Essentially, in this mode of operation, the Utility power is supplying the load.
1.3.2. Online Mode
Applying Utility power to the input with the Bypass switch in its Auto/UPS position will place the unit into its Online
Mode. The battery charger is activated allowing the batteries to charge. The control boards will power-up and a
series of system test are performed. If all test are passed, the user can request through the pressing of a button or
throwing of a switch that the inverter turns on. The controlling CPU will signal the user via the unit’s display that the
inverter has been turned-on.

1.3.3. Standby Mode
After power is applied, a self-check starts. During this period, the start subroutine checks for the input voltage and
proper operation of the inverter. After the routine is completed and checks conrmed to be OK, the system goes into
the Standby mode.
1.3.4. Response To Total Input Power Failure
When input powers sources fails, the battery bank becomes a DC supply source to the inverter; allowing the pro-
tected load to be maintained for a nite amount of time (Based on the runtime of the unit). The Control panel will
display a message indicating that the battery is discharging. When the input power returns, the message will be
extinguished, battery begin to charge, and the system returns to the mode that it was in prior to the outrage. If the
battery voltage drops below the Battery manufacturer’s recommended level and the facility power remains off, the
system will turn-off.
1.3.5. UPS Failure
The System controller will issue a FAILURE message, turn-off the inverter, or shutoff the unit when certain conditions
occur (Refer to Appendix). During a FAILURE, the system stops its backup operation and remains in this mode until
power is cycled or the system has been repaired.
1.3.6. UPS Problem
The System controller will issue a UPS PROBLEM message on the display if any of the following conditions occur:
• Input power failure
• Output overload
During an input power failure, the inverter remains on and the battery will supply power up to the time that the voltage
drops below 10Vdc per battery. The system will reset itself as soon as the problems disappears. During an output
overload, the inverter turns off and an alarm signal will be sent to the signal interface. A manual reset is required
once the problem is cleared.
1.4. OUTPUT LOADS
The Three Phase inverter is designed to power any lighting system. There are, however, certain types of loads that exhibit
an excessive inrush current when rst turned on or at other times during operation. The capacity of the Fortress 3 may
need to be greater than what would be estimated based on the system label requirements of loads previously discussed.
Contact the factory directly if you have any questions about powering unusual loads from your Fortress 3.

1.6.A. Normal Operation
During normal operation, the path through the Contactor and Static Bypass switch is used to power the load. Refer-
ring to Figure 1: the rectiers convert Input AC power to DC. DC power is utilized to charge the UPS battery system
(AC to DC Rectier). The Inverter also convert AC to DC (Rectier) to be able to generate AC power to supply the
critical load when the 3Φ source is lost. The conversion - inversion process eliminates any voltage transients or
uctuations existing in the input power before it reaches the critical load.
1.6.B. MANUAL BYPASS OPERATION
Refer to Figure 2. A Manual Bypass Switch is provided as a standard feature of the DSPM’s UPS. This switch is
to bypass the inverter logic incase of failure, to enable the end user function until service can be performed. The
advantage of this form of bypass is that the input ltering is still providing protection to the critical loads on the UPS.
Figure 2 illustrates the ow diagram when the UPS has been manually bypassed.

1.6.C. AC Loss/Battery Operation
Referring to Figure 3, if input powers is interrupted, the Battery bank will immediately supply the DC power required
by the Inverter to maintain continuous AC power to the load. A fully charged battery bank will provide power for the
specied time at the rated load, or longer at reduced load.
In the event of a power failure, the rectiers will de-energize and the batteries will discharge into the Inverter and
maintain power to the critical load until a) the battery capacity expires and the inverter turns off, or b) input power is
restored after which the rectiers will power the inverter and simultaneously recharge the batteries. Figure 3 illus-
trates the ow diagram during battery operation.
When power is restored after a low battery shutdown, the rectiers automatically restart and, recharge the batteries
and the Inverter is automatically restarted without operator intervention. The inverter automatically, without operator
intervention, resumes powering the Rectier.

1.6.D. External Maintenance Bypass (EMB) Operation (Optional)
There is an optional External Maintenance Bypass which supplies the critical load with unconditioned input power .
The purpose of this option is to route power to the critical load while the UPS’ rectier and inverter are de-energized,
and during Start-up before the system is fully operational (refer to Figure 4).
With the External Maintenance Bypass there is a hard wired bypass that can be operated after the Static Bypass
Switch has been operated, making it possible to isolate the entire UPS for service and maintenance. The internal
control system determines the operation of the normal and External Maintenance Bypass paths, with the load pow-
ered from the inverter being the normal operation.
