The UPS has been designed in accordance with and complies with the following standards;

1. UL 1778 (Underwriter Laboratories) Standard for UPS Equipment.

2. CSA 22.2 (Canadian Standards Association – cUL Equipment).

3. IEC (International Electro-technical Commission) Semiconductor Converter Standards.

4. EMI compatibility: FCC Title 47, Part 15, Subpart B

5. IEEE 587, ANSI C62.41 1991 Standard for Surge Withstand Ability.

6. ISO 9001 Quality Assurance program.

1.3.1 Components

The UPS system shall consist of the following major equipment;

1. Insulated Gate Bipolar Transistor (IGBT) Converter.

2. Insulated Gate Bipolar Transistor (IGBT) Inverter.

D. MODBUS/TCP Communication

E. ENVIRO – Static Transfer Switch (ESTS) (option)

F. Maintenance bypass cabinet (option).

G. Remote status alarm panel (option).

1.3.2 Mode of Operation

The UPS shall be designed to operate continuously at rated capacity as an on-line/double conversion, automatic reverse transfer system in the following modes :

A. Normal - The inverter continuously supplies AC power to the critical load by converting the utility AC power source to regulated DC power source. The DC serves as the inverter input and as the battery systems float charge.


U-ENS00057, REV 2

B. Emergency - In the event of a utility AC power failure, the inverter shall derive its input from the system battery, therefore providing uninterrupted power to the critical load.

This transition shall be accomplished without any switching or coupling, and with no interruption of power to the critical load from either a failure or restoration of the utility

AC power.

C. Recharge - Subsequent to restoration of utility AC power, the converter shall automatically reactivate and provide DC power to the inverter, simultaneously recharging the system battery. This occurs automatically and without interruption to the critical load.

D. Bypass - In the event that the UPS must be taken off line due to an overload condition or

UPS failure, the critical load shall be transferred to the bypass source via the static switch without interruption of AC power to the critical load. A paralleling, wrap-around contactor shall be used to maintain the bypass source. The static switch shall only be utilized for automatic emergency transfers. A re-transfer from bypass to inverter shall be performed automatically in overload conditions. A re-transfer shall be inhibited if satisfactory synchronization of the inverter and bypass is not accomplished. The use of the static switch shall not be required during the manual or automatic re-transfer process, therefore increasing reliability.

E. ENVIRO Mode (Optional): The UPS shall be supplied using double conversion technology with an option that allows the user to transfer to a high efficiency (ENVIRO) operating mode. In the ENVIRO mode, the UPS shall supply power to the critical load through the UPS internal bypass. The bypass shall have an integral ENVIRO Static

Transfer Switch (ESTS) that provides a smooth transition to inverter operation during emergency mode operation.

F. Input Current Limit

The Converter logic shall provide input current limiting by limiting the AC input current.

Three (3) line-side current transformers shall be employed as a means of sensing the current amplitude. The Converter shall also provide sufficient capacity to provide power to a fully loaded inverter while simultaneously recharging the system battery to

90% of full capacity within 20 times the discharge time. The AC input current limit values are as follows:

1. Battery charge current limit: 10% of battery Ah rate.

2. Maximum charge current: 16% ampere of UPS rated kVA.

C. Equalize Charge Timer

UPS Module logic and control shall provide an electronic equalize charge timer function

(0 to 100 hour selectable - default twenty-four (24) hour). Once activated the timer circuit shall provide a high rate equalizing charge voltage to the system battery for the selected time. The function can be manually activated and de-activated via the UPS Module LCD.

The level of equalizing voltage shall be equal to that stated by the battery manufacturer

(typically .04 to .08 VDC/cell higher than the specified float level). Upon completion of the timer count, the converter output voltage shall return to the specified float voltage

(typically 2.25 to 2.27 VDC/cell). An Auto Equalize charge operation is also provided following AC input restoration and subsequent to the power walk in function. This equalizing charge will occur until the battery target voltage is reached (condition is met to end equalizing charge), in which float voltage will be applied.

D. Temperature Control Battery Charging

The UPS shall have as standard a battery temperature compensation function allowing the converter voltage to fold-back to a safe value in the event the battery system temperature reaches a pre determined (dangerous) level. Initiation will be by dry contact input from thermocouple sensor (User supplied)

E. DC Input protection

The DC input circuit shall be protected by a DC circuit breaker. The DC circuit breaker allows complete interruption of DC current and isolation of the UPS Module DC input and the battery system.

The DC Circuit breaker shall incorporate an UVR and auxiliary contact connections to the UPS Module control for prevention of incorrect start up and shutdown sequencing.

The DC Circuit Breaker shall be provided as standard equipment.


U-ENS00057, REV 2

The UPS shall provide for maximum battery life by limiting the DC (battery) bus RMS ripple voltage to less than 2% of the UPS nominal DC voltage level at 100% load.

1. The Diamond-Sense Battery Self-Test function can be performed even when load is on inverter.

2. Due to the short duration small power discharge, there is no effect to battery life expectancy.

3. The small power discharge has negligible effect on the overall battery back up time.

The small power that is discharged by the battery will quickly be replenished.

The Battery Self Test will automatically occur every 720 hour interval. An event alarm will occur and be displayed if battery abnormalities are detected.

D. Voltage Transient Response

Normal Mode

The dynamic regulation and transient response shall not exceed +/- 2% for 100% step load (applied or removed), +/- 1% for loss or return of AC input and +/-5% for inverter to bypass and vice versa transfer.

Voltage transient response shall not exceed the above specification and shall recover to within nominal voltage regulation tolerance within 20 ms

The Inverter output frequency shall be controlled by an oscillator internal to the UPS module logic. It shall be capable of synchronizing to an external reference (e.g.; the bypass source) or operating asynchronously. A message located on the touch screen shall identify the loss of synchronization. Synchronization shall be maintained at 60 Hz

+/- 0.01% continuously for the duration of loss of the external reference. The Inverter output frequency shall not vary during steady state or transient operation due to the following conditions:

1. 0 to 100% loading.

2. Inverter DC input varies from maximum to minimum.

3. Environmental condition variations within the specifications defined herein.

G. Output Voltage Harmonic Distortion

The inverter output shall limit the amount of harmonic content to 2% maximum at 100% linear load, and 5% maximum at 100% non-linear load. The need for additional filtering to limit the harmonic content shall not be required. Therefore high efficiency, reliability and original equipment footprint are maintained.


U-ENS00057, REV 2

H. Output Overload Capability

The inverter output shall be capable of providing an overload current while maintaining rated output voltage (and voltage regulation) to:

105% to 125% for 2 minute duration.

126% to 150% for 1 minute duration.

The UPS Module Operation/Display panel LED indication will illuminate to identify an overload condition. If the time limit associated with the overload condition expires or the overload is in excess of the set current, the load power shall be transferred to the bypass source without interruption.

I. Inverter Current Limit

The inverter output current shall be limited to 240% of rated load current. Two current transformers in separate locations on the output (and operating separately offering redundancy) shall be employed as means of current sensing.

The inverter current limit protects inverter components from damage due to excessive over-current (Excessive load, faults and reverse current)

J. Inverter Output Isolate

The inverter output contactor isolates the inverter from the load and bypass source.

2.2.3 UPS Module Control and Monitoring

A. UPS Module Control and Monitoring operates and controls the converter, inverter and independent automatic bypass static switch circuit

B. The UPS Module control circuitry utilizes Digital Signal Processor (DSP) and Application

Specified IC (ASIC) which creates advanced controllability and simplify the control circuit. Direct Digital Control (DDC) utilizing DSP and ASIC ensures high reliability, as well as superior functionality and performance.

C. The UPS Module utilizes unique Major and Minor Feed Forward Current Loop Control, enabling instantaneous control of UPS Module output. The digitalized UPS Module incorporates Field Programmable Gate Array (FPGA) for Current Minor Loop Control, and DSP based control for Feed Forward Control and Voltage Major Loop Control. DSP

Sampling Frequency is 48.0 kHz, therefore the control samples 800 times in 1 cycle of output voltage. Output voltage can therefore be controlled with high precision.

D. All UPS Module Control and Monitoring printed circuit boards shall be effectively sealed to protect against corrosive vapors.

E. The UPS Module Control power supply employs a redundant design configuration, utilizing the UPS AC input (utility), Bypass input and the UPS Module inverter output therefore enhancing reliability.


U-ENS00057, REV 2

2.2.4 Bypass and Static Switch

UPS module contains an automatic bypass static switch circuit and associated bypass static switch transfer control circuitry.

A. General

A bypass circuit shall be provided as an alternate source of power other than the inverter.

A high speed Thyristor switch and wrap-around contactor shall be used to assume the critical load during automatic transfers to the bypass circuit. The static switch and wrap-around contactor shall derive power from an upstream bypass feed contactor internal to the UPS module. The wrap-around contactor shall be electrically connected in parallel to the static switch and shall, at the same time as the static switch, be energized and upon closure maintain the critical load feed from the bypass source. The static switch shall only be utilized for the time needed to energize the wrap-around contactor therefore increasing reliability. The bypass circuit shall be capable of supplying the

UPS rated load current and also provide fault clearing current capabilities. The UPS system logic shall employ sensing which shall cause the static switch to energize within

150 microseconds therefore providing an uninterrupted transfer to the bypass source when any of the following limitations are exceeded:

1. Inverter output undervoltage or overvoltage.

2. Overloads beyond the capability of the inverter.

3. DC circuit undervoltage or overvoltage.

4. Final voltage of system battery is reached (bypass source present and available).

5. System failure (e.g.: logic fail, fuse blown, etc.).

In the event that the critical load must be transferred to the bypass source due to an overload, the UPS system logic shall monitor the overload condition and, upon the overload being cleared, perform an automatic re-transfer back to the inverter output.

The UPS system logic shall only allow a re-transfer to occur three times within a five minute period. Re-transfers shall be inhibited on the fourth transfers due to the likely hood of a recurring problem at the UPS load distribution. All retransfers will be inhibited if the inverter and static bypass line are not synchronized.

C. Manual Transfers

The UPS shall be capable of transferring the critical load to/from the bypass source via the front control panel. If performing manual retransfers to inverter or automatic retransfers, the UPS system logic shall force the inverter output voltage to match the bypass input voltage and then parallel the inverter and bypass sources providing a make-before-break transition allowing a controlled walk-in of load current to the inverter.

Manual transfers will be inhibited if the inverter and static bypass line are not synchronized.

D. Static Switch

The static switch shall be a high speed transfer device comprised of naturally commutated Thyristor's. During manual transfers the static switch is not required.

The static switch shall not use fuses for protection.


U-ENS00057, REV 2
