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 8
The Power Bus Bar for parallel systems, mounted in the rear of an HP rack, provides the required input and
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 11
CAUTION:
•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-384-
48 S1, “Electrical Installation of the Buildings, Part 4: Protection for Safety, Chapter 46:
Isolation 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 4–0.32 mm2 (12–22 AWG) 0.82 mm2 (18 AWG)
L2 4–0.32 mm2 (12–22 AWG) 0.82 mm2 (18 AWG)
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.

Selecting a site
WARNING: To prevent fire or electric shock, install the unit in a temperature- and
humidity-controlled indoor environment, free of conductive contaminants.
When selecting a site, consider the following factors:
•Elevated operating ambient temperature—If the equipment is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment might be greater than room
ambient temperature. Install the equipment in an environment compatible with the operating
temperature ("Environmental specifications" on page 103).
•Reduced air flow—In the rack, the rate of air flow required for safe operation of the equipment must not
be compromised.
•Circuit overloading—Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing
this concern.
•Reliable earthing—Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit, such
as the use of power strips.
•Electrical requirements—All models require a dedicated (unshared) branch circuit, suitably rated for the
specific UPS as stated in "Input specifications" .
Readying the equipment
