3 Phase UPS overview

The HP 3 Phase UPS protects your sensitive electronic equipment from the most common power problems including power failures, power sags, power surges, brownouts, and line noise.

Power outages can occur when you least expect it and power quality can be erratic. These power problems have the potential to corrupt critical data, destroy unsaved work sessions, and damage hardware - causing hours of lost productivity and expensive repairs.

With the HP 3 Phase UPS, you can safely eliminate the effects of power disturbances and guard the integrity of your equipment. The HP 3 Phase UPS is designed for critical applications such as ultra high—density blade servers in a data center environment.

Providing outstanding performance and reliability, the HP 3 Phase UPS unique benefits include:

• High-density three-phase input, three-phase output UPS

• Scalable to 60 kW (redundant N+1 configuration) by connecting up to six additional parallel UPS

modules. Each UPS in the parallel system connects to a Power Bus Bar pre-installed in the rear of a rack. Racks

can be configured for bottom or top entry A Parallel UPS Card in each paralleled UPS provides connectivity for system metering and operational

mode control. In a parallel system not fully loaded, the system will shift load to UPSs with the strongest batteries or additional ERMs to maximize runtime when on battery. Parallel systems can be configured for capacity or redundancy.

• 6U UPS height, 3U ERM height

• Normal operating mode that minimizes heat generation by operating at typically >98% efficiency

The UPS filters incoming AC power and provides consistent power to your equipment without draining the battery.

• For utility line input that exceeds normal operating range, automatic transfer to an online,

double-conversion, high-frequency UPS design with pure sine wave output and power-factor correction

• EBM technology that uses advanced battery management to increase battery service life, optimize

recharge time, and provide a warning before the end of useful battery life

• Extended runtime with up to four ERMs per UPS

• Hot-swappable electronics module and batteries that simplify maintenance by allowing you to replace

them safely without powering down the critical load

• Emergency shutdown control through the REPO port

• HP UPS Management Module for network connectivity with monitoring and control

• Firmware that is service upgradeable through the standard DB-9 communication port

• Backed by worldwide agency approvals

Component identification 7

The Power Bus Bar for parallel systems, mounted in the rear of an HP rack, provides the required input and

LED display

output connections for the paralleled UPSs and has a single system-rated input connection. The parallel UPS system can be installed with Output Power Modules or connected to rack-mounted power distribution systems.

Note these guidelines when configuring the UPS standalone unit or parallel system:

• There is a maximum of four ERMs per UPS.

• Mount ERM(s) for a standalone UPS directly below the UPS or, with rack side panels removed, in an

adjacent rack to the left of the rack containing the UPS.

• Mount ERMs for a parallel system in an adjacent rack to the left of the rack containing the UPSs (rack

side panels removed).

• For consistent runtimes, each UPS in a parallel system should have the same number of ERMs.

• Some load equipment may require phase rotation or phase relationship coordination to ensure proper

operation. Review your equipment manufacturer’s power requirement documents to ensure that your connected equipment operates correctly.

REPO port

WARNING: The REPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit

must be separated from any hazardous voltage circuits by reinforced insulation.

Component identification 10

CAUTION:

48 S1, “Electrical Installation of the Buildings, Part 4: Protection for Safety, Chapter 46:

• Do not connect the REPO port to any utility connected circuits. Reinforced insulation to the

utility is required. The REPO switch must have a minimum rating of 24 Vdc and 20 mA and be a dedicated latching-type switch for the 3 Phase UPS only, no other device or circuit including a single phase UPS. The REPO signal must remain active for at least 250 ms for proper operation.

• To ensure that the UPS stops supplying power to the load during any mode of operation, the

input power must be disconnected from the UPS when the EPO function is activated.

NOTE: For Europe, the emergency switch requirements are detailed in Harmonized document

HD-384Isolation and Switching.”

The UPS includes an isolated REPO port. When properly wired, the REPO feature allows the power at the UPS output receptacles to be switched off from a remote location. When REPO is activated, the UPS powers down all converters, de-energizes all system relays, trips the UPS battery circuit breaker, and powers down within 10 to 15 seconds. However, the unit continues to have logic power (the display is still active) and is not fully powered down until input power is disconnected from the unit. This feature can be used for powering down the load and the UPS by thermal relay, for example in the event of room overtemperature.

To use this feature, the REPO port must be connected to a remote switch (not supplied). The REPO switch is used in conjunction with a main disconnect device that removes the AC source from the input of the UPS. When the switch is activated:

• The REPO feature immediately powers down protected devices and does not utilize the orderly

shutdown procedure initiated by power management software.

• The REPO feature shuts down UPS units operating under either utility or battery power.

Keep the REPO connector installed in the REPO port on the UPS even if the REPO function is not needed. The REPO connection are listed below:

Wire function Terminal wire size rating Suggested wire size

L1 L2

There are two REPO positions, normally-open (NO) or normally-closed (NC). The pins on the NC REPO connector are connected together. When this connection is open, the logic circuitry completely shuts down the UPS, thus preventing the power from supplying the load. To use NC REPO, remove the jumper wire and connect an NC external switch. To use NO REPO, connect an NO external switch. For REPO locations, see Connecting REPO port

NOTE: If the UPS was operating on battery power when the remote switch was closed, no power

is available to the load devices until utility power is restored and the UPS has been manually powered up.

To restore power to the load devices after the REPO feature is activated, press the Power On button after the AC source is reconnected to the UPS.

IMPORTANT: Pressing and holding the Power On button without utility present normally initiates

a battery start and the UPS assumes the load. However, if the Power On button is pressed and a REPO is detected, battery start is inhibited and the UPS is not able to assume the load. The electronics module fan spins and the Alarm LED and an audible alarm are active as long as the Power On button is held.

• No power is available at the UPS output receptacles.

• The UPS charges the batteries as necessary.

The UPS can be placed in Standby mode when the UPS is in Normal mode (on page 65). To place the UPS in Standby mode:

1. Power down the UPS.

UPS operations 64

Standalone UPS configuration—See "Powering down the standalone UPS (on page 72)."

o Individual UPS in a parallel configuration—See "Powering down an individual paralleled UPS (on

page 72)."

o Parallel UPS configuration—See "Powering down the parallel system (on page 73)."

2. Power to the load ceases.

IMPORTANT: While in Standby mode, the UPS maintains the charge on the batteries, but no

power is available at the output receptacles. The UPS remains in Standby mode until an alternate mode is selected or until utility power is removed.

Normal mode

In Normal mode:

• Power is available at the UPS receptacles.

• The UPS charges the batteries as necessary.

Depending on input power conditions, the UPS automatically changes modes. The UPS has three types of Normal mode:

• Standard mode (on page 65)

• Full-Time Standard mode (on page 65)

• High Efficiency mode (on page 65)

Standard mode

If the input line exceeds normal operating range, the UPS transfers to Standard mode (Online mode) to produce a regulated output voltage. When the input line returns to normal operating range, the UPS returns to High Efficiency mode (on page 65).

Full-Time Standard mode

Full-Time Standard mode (continuous Online mode) is user selectable for full-time operation.

High Efficiency mode

By default, the UPS operates in a High Efficiency mode that minimizes heat contribution to the rack environment. The system bypass input directly supplies the system output with three-phase AC power, and the UPS automatically transfers to double-conversion (Normal mode (on page 65)) operation as needed. The battery recharges as necessary.

Continuous double-conversion mode

Continuous double-conversion mode is available only for loads less than 10 kW (86%). If the load exceeds the 10 kW limit while in Standard mode, the UPS switches to High Efficiency mode until the load is reduced below 9 kW. After three attempts within one hour to operate in Standard mode, the UPS locks into High Efficiency mode for one hour to prevent continuous cycling.

Running automatic battery tests

Battery tests rely on backfeeding the utility, using the utility as a load. Some sites might choose to disable battery testing if their source is not capable of being backfed. Examples of such sources include generators, other UPSs, and other stiff or soft sources. If a source is not capable of being backfed, the UPS aborts the test (due to utility failure) and maintains the load and log the event. Further consequences depend on the source (for example, another UPS feeding the BladeUPS module might trip off).

NOTE: For automatic and manual battery tests, the UPS determines when it is appropriate to run

To disable battery testing:

1. Press any button on the front panel display to activate the menu options.

Control terminals

The cables should be connected to the control terminal with a mating connector. Input and output terminals have a functional isolation from terminal to terminal. They are connected to the UPS chassis through individual 1 MW resistors.

If using a semiconductor switch type, pay attention to the proper polarity. A relay or other mechanical control is preferred.

Relay output contacts

WARNING: The relay output contacts must not be connected to any utility connected circuits.

Reinforced insulation to the utility is required. The relay output contacts have a maximum rating of 30 VAC/1 A and 60 Vdc/2 A nominal values.

Communication 76

The UPS incorporates a programmable relay output with potential free contacts for remote alarm indications.

These alarms can be activated separately or at the same time with other building

An additional four relay outputs can be obtained with the compatible Relay Interface option card.

Program for all UPSs in a parallel system.

Use the programmable signal inputs to emulate some of the features usually seen on larger 3-phase systems. For example:

• Configure the signal from a smoke detector or water leak detector to power down the system.

• Configure a vibration sensor or air conditioner sensor to power down the system.

• Set actions for alarms from a generator, such a disabling the charger for an undersized generator or

shutdown for a failed generator.

• Configure an ATS sensor to transfer the system to Auto-Bypass mode.

Parallel communication

The Parallel UPS Card in each paralleled UPS provides connectivity for system metering and operational mode control. Powering up, powering down, and auto-calibration commands given at one UPS also command the other UPSs in the parallel system. The UPSs in a parallel system are in constant communication to monitor settings and status information.

Communication 77

Mode transfers

• If one UPS in a parallel system transfers from High Efficiency mode (on page 65) to Normal mode (on

page 65), the other UPSs transfer also.

• If one UPS transfers to Battery mode (on page 66), the remaining UPSs in the parallel system stay online.

The transferred UPS might transfer back to online at any time, and the parallel system resynchronizes.

• When a parallel system is on battery power , the front panels of each UPS display the battery status

information of the UPS with the lowest runtime remaining. When the first UPS shuts down, the other UPSs also shut down.

• In a parallel system configured for redundancy, the UPSs use a distributed bypass, and the following

alarms cause an individual UPS to power down instead of transferring to Auto-Bypass mode (on page

66):

o Failure of the fan, fuse, temperature sensor, or power supply o Inverter AC under voltage o Battery current limit o DC line under voltage o Battery over voltage

Redundant signal wiring

The redundant signal wiring provides redundant backfeed protection in case of Parallel UPS Card failure in the parallel system. If the card fails, the UPSs transfer to Normal mode (on page 65). The system runs unsynchronized, and any UPS can transfer to Battery mode (on page 66) as necessary. If any UPS must transfer to Auto-Bypass mode (on page 66), the redundant signal wiring allows the entire parallel system to transfer to Auto-Bypass mode, without backfeeding.

Auto-identification

The UPS parallel system automatically assigns identities to each UPS in the system. To take advantage of this feature, wire the Parallel UPS Cards together. For more information, see "Installing in a parallel configuration (on page 26)."

Upon powering up the UPS, the UPS with the initializing jumper installed identifies itself as UNIT 1. The next UPS wired identifies itself as UNIT 2, and so forth. The auto-identification sequence takes about 15-20 seconds to complete after all the UPSs in the parallel system have logic power.

If a UPS is powered down or otherwise loses logic power, the UPS re-identifies itself in the proper sequence after logic power is restored.

If a UPS is powered down and removed from the parallel system, the other UPSs in the system do not re-identify themselves to compensate for the missing UPS until logic power to all the UPSs is cycled. For example, if you remove UNIT 2 and rewire UNIT 3's Parallel UPS Card IN port to UNIT 1's Parallel UPS Card OUT port, UNIT 3 does not re-identify itself as UNIT 2 until logic power is cycled. The Parallel UPS Cards for UNIT 1 and UNIT 3 continue to function normally without the need to re-identify.

Communication 78

Metering

The Output and Load Receptacle meter readings differ between a parallel system and a standalone UPS. In a parallel system, one UPS reads the Load Receptacle value for the total system (the others read zero), but each UPS displays its own Output value. For example, in a two-unit parallel system with one Anderson load connection for 12 kVA, the Load Receptacle current would read 12 kVA on one UPS and zero on the other UPS, but the Output measurement would be 6 kVA on each UPS (half the total). In a standalone UPS, the load can be connected from the outlet cord or the Anderson load connector. The Output measurement would be the total load on the UPS, and the Load reading would be the portion supplied by the Anderson load connector.
