Chapter 1 Introduction

The Eaton®93E 40–60 kVA uninterruptible power supply (UPS) is a true online, continuous-duty,

transformerless, double-conversion, solid-state, three-phase system, providing conditioned and uninterruptible

AC power to protect the customer's load from power failures.

The Eaton 93E 40–60 kVA online power protection system is used to prevent loss of valuable electronic

information, minimize equipment downtime, and minimize the adverse effect on production equipment due to

unexpected power problems.

The Eaton 93E 40–60 kVA UPS continually monitors incoming electrical power and removes the surges, spikes,

sags, and other irregularities that are inherent in commercial utility power. Working with a building's electrical

system, the UPS system supplies clean, consistent power that sensitive electronic equipment requires for

reliable operation. During brownouts, blackouts, and other power interruptions, batteries provide emergency

power to safeguard operation.

The UPS is housed in a single free-standing cabinet, with safety shields behind the door for hazardous voltage

protection. Figure 1-1 shows the Eaton 93E 40–60 kVA UPS.

Figure 1-1. Eaton 93E UPS (40–60 kVA)

NOTE 1 Startup may be performed by the customer’s battery qualified electrical contractor

for single (not parallel) UPS installations without any accessory cabinets such as an

External Battery Cabinet.

NOTE 2 Startup and operational checks for parallel systems or installations with accessory

cabinets must be performed by an authorized Eaton Customer Service Engineer, or

the warranty terms specified on page W-1 become void. This service is offered as

part of the sales contract for the UPS. Contact an Eaton service representative in

advance (usually a two-week notice is required) to reserve a preferred startup date.

Introduction

1-2 Eaton 93E UPS (40–60 kVA, 208/220V) Generation 3 Installation and Operation Manual P-164000302—Rev 3

1.1 UPS Standard Features

The UPS has many standard features that provide cost-effective and consistently reliable power protection. The

descriptions in this section provide a brief overview of the UPS standard features.

1.1.1 Installation Features

Power wiring can be routed to the back of the cabinet with connections made to easily accessible terminals.

Control wiring can be installed using conduit through the bottom of power terminal cover base or by routing

wiring through the power terminal cover base wiring channels and must be installed in accordance with Class 1

wiring methods.

1.1.2 Control Panel

The control panel, located on the front of the UPS, contains a liquid crystal display (LCD) and pushbutton

switches to control the operation of the UPS and to display the status of the UPS system. See Chapter 6, “UPS

Operating Instructions,” for additional information.

1.1.3 Customer Interface

lBuilding Alarm Monitoring – Up to three inputs in the UPS are available to connect the facility's alarm

system contacts. Some system configurations may limit the number of inputs available. The UPS uses

these inputs to monitor the building alarms in addition to the UPS status. See Chapter 7, “Communication,”

for additional information.

lMini-Slot Communication Bays – Two communication bays are standard equipment. One to two optional

Mini-Slot®connectivity cards can be installed in the UPS module at any time. Mini-Slot cards are quickly

installed at the rear of the UPS and are hot-pluggable. See Chapter 7, “Communication,” for additional

information.

1.1.4 High-Efficiency Normal Mode

The 93E Series UPS offers a High-Efficiency (HE) normal mode with double-conversion on demand that allows

the UPS to operate in standby bypass mode. This mode allows the 93E UPS to achieve 98% efficiency while

still protecting the load. High-efficiency mode is the default normal operating mode. See Chapter 6, “UPS

Operating Instructions,” for additional information.

1.1.5 Battery System

The battery system provides emergency short-term backup power to safeguard operation during brownouts,

blackouts, and other power interruptions. The battery system is equipped with lead-acid batteries.

protection breakers sized for a fully rated UPS.

lFor external wiring, use 90°C copper wire. Wire sizes listed in Table 3-5 are for copper wiring only. If wire is

run in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may be

necessary. Wire sizes are based on using the specified breakers.

lWire ampacities are chosen from Table 310-16 of the National Electrical Code® (NEC®). Specification is for

copper wire with a 90°C rating.

lMaterial and labor for external wiring requirements are to be supplied by designated personnel.

lIf installing an external maintenance bypass, all feeds to the UPS including the Rectifier Input Breaker (RIB)

(if installed) must have a service disconnect independent of the maintenance bypass power path. Most

maintenance bypass solutions provide UPS input feeds derived from but isolated from the maintenance

bypass power path. If the maintenance bypass solution being installed does not provide such functionality,

DO NOT use a single feeder breaker to supply both the UPS and the maintenance bypass.

Chapter 5 Understanding UPS Operation

5.1 UPS System Overview

The Eaton 93E UPS is a continuous-duty, solid-state, transformerless, three-phase, true online system that

provides conditioned and uninterruptible AC power to the UPS system's output and critical load.

The basic system consists of a rectifier, battery converter, inverter, monitoring/operation control panel,

integrated communication server, and digital signal processor (DSP) logic. Figure 5-1 shows the main elements

of the UPS system.

If utility power is interrupted or falls outside the parameters specified in Chapter 9, “Product Specifications,”

the UPS uses a backup battery supply to maintain power to the critical load for a specified period of time or

until the utility power returns. For extended power outages, the UPS allows you to either transfer to an

alternative power system (such as a generator) or shut down your critical load in an orderly manner.

Figure 5-1. Main Elements of the UPS System

The emergency bypass consists of a continuous static switch, and a bypass switchgear. The bypass switchgear

is located in series with the static switch. The static switch is armed and ready during normal operation.

5.2 Single UPS

A single UPS operates independently to support an applied load from the inverter, providing conditioned and

uninterruptible AC power to the critical load from the output of the module. During an outage, the inverter

continues to operate, supporting power to the load from the battery supply. If the unit requires service, applied

loads are transferred to the internal bypass either automatically or manually. With the exception of an optional

external battery cabinet, no other cabinets or equipment are required for the single UPS to successfully support

its applied loads.

5.2.1 Modes

The Eaton 93EUPS supports a critical load in four different modes of operation:

lIn High-Efficiency (HE) Normal mode, commercial AC power is supplied directly to the critical load through

the internal bypass and transfers automatically to Standard Normal mode (double-conversion on demand) if

an abnormal condition is detected. HE mode is the default normal operating mode.

lIn Standard Normal mode, the critical load is supplied by the inverter, which derives its power from rectified

utility AC power. In this mode, the battery charger also provides charging current for the battery, if needed.

lIn Bypass mode, the critical load is directly supported by utility power.

lIn Battery mode, the battery provides DC power, which maintains inverter operation. The battery supports

the critical load.

The following paragraphs describe the differences in the UPS operating modes, using block diagrams to show

the power flow during each mode of operation.

5.2.2 High-Efficiency Normal Mode

When the UPS is operating in HE mode, commercial AC power is supplied directly to the critical load through

the internal bypass with the power module in a standby state. If a commercial power brownout, blackout,

overvoltage, undervoltage, or out-of-tolerance frequency condition occurs the system forward transfers to

normal mode (double-conversion on demand) or battery mode. When the input line returns to normal operating

range, the UPS returns to HE operation. For charging batteries in HE mode, the UPS will revert to normal mode

to charge the batteries, then return to HE mode when charge cycle is complete.

HE mode is the default normal operating mode, and not an alarm condition. While the UPS is in this mode, the

NORMAL light on the front display will illuminate.

5.2.3 Standard Normal Mode

During Standard Normal mode, power for the system is derived from a utility input source through the rectifier

switchgear. Three-phase AC input power is converted to DC using IGBT devices to produce a regulated DC

voltage to the inverter. When the battery switchgear is closed the battery is charged directly from the regulated

rectifier output through a buck or boost DC converter, depending on the system voltage and the size of the

battery string attached to the unit.

Figure 5-2 shows the path of electrical power through the UPS system when the UPS is operating in Normal

mode.

The battery converter derives its input from the regulated DC output of the rectifier and provides either a

boosted or bucked regulated DC voltage charge current to the battery. The battery is always connected to the

UPS and ready to support the inverter should the utility input become unavailable.

The inverter produces a three-phase AC output to a customer's load without the use of a transformer. The

inverter derives regulated DC from the rectifier and uses IGBT devices and pulse-width modulation (PWM) to

produce a regulated and filtered AC output. The AC output of the inverter is delivered to the system output

through the inverter switchgear.

If the utility AC power is interrupted or is out of specification, the UPS automatically switches to Battery mode

to support the critical load without interruption. When utility power returns, the UPS returns to Normal mode.

If the UPS becomes overloaded or unavailable, the UPS switches to Bypass mode. The UPS automatically

returns to Normal mode when the overload condition is cleared and system operation is restored within

specified limits.

If the UPS suffers an internal failure, it switches automatically to Bypass mode and remains in that mode until

the failure is corrected and the UPS is back in service.

5.2.4 Bypass Mode

CAUTION

The critical load is not protected from voltage or frequency fluctuations or power outages while

the UPS is in Bypass mode.

The UPS automatically switches to Bypass mode if it detects an overload, load fault, or internal failure. The UPS

can also be transferred from Normal mode to Bypass mode manually. The bypass source supplies the

commercial AC power to the load directly. Figure 5-3 shows the path of electrical power through the UPS

system when operating in Bypass mode.

In Bypass mode, the output of the system is provided with three-phase AC power directly from the system

input. While in this mode, the output of the system is not protected from voltage or frequency fluctuations or

power outages from the source. Some power line filtering and spike protection is provided to the load but no

active power conditioning or battery support is available to the output of the system in the Bypass mode of

operation.

The internal bypass is comprised of a solid-state, silicon-controlled rectifier (SCR) continuous static switch, and

the bypass switchgear. The static switch is used instantaneously anytime the inverter is unable to support the

applied load. The continuous static switch is wired in series with the bypass switchgear, and together they are

wired in parallel with the rectifier and inverter.

The static switch, being an electronically-controlled device, can be turned on immediately to pick up the load

from the inverter while inverter switchgear opens to isolate the inverter. The bypass switchgear is normally

closed, ready to support the static switch unless the bypass input source becomes unavailable.

If the UPS transfers to Bypass mode from Normal mode due to any reason other than operator intervention,

the UPS automatically attempts to transfer back to Normal mode (up to three times within a ten minute period).

The fourth transfer locks the critical load to the bypass source and requires operator intervention to transfer.

5.2.5 Battery Mode

The UPS automatically transfers to Battery mode if a utility power outage occurs, or if the utility power does

not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the

inverter converts to AC power.

Figure 5-4 shows the path of electrical power through the UPS system when operating in Battery mode.

Figure 5-4. Path of Current Through the UPS in Battery Mode

During a utility power failure, the rectifier no longer has an AC utility source from which to supply the DC output

voltage required to support the inverter. The rectifier switchgear opens and the battery instantaneously

supplies energy to the battery converter. The converter boosts the voltage so that the inverter can support the

customer's load without interruption. If bypass is common with the rectifier input, the bypass switchgear also

opens. The opening of the rectifier and the bypass switchgear prevent system voltages from bleeding

backwards through the static switch and rectifier snubber components to the utility source.

If the input power fails to return or is not within the acceptance windows required for normal operation, the

battery continues discharging until a DC voltage level is reached where the inverter output can no longer

support the connected loads. When this event occurs, the UPS issues another set of audible and visual alarms

indicating SHUTDOWN IMMINENT. Unless the rectifier has a valid AC input soon, the output can be supported

for only two minutes before the output of the system shuts down. If the bypass source is available, the UPS

transfers to bypass instead of shutting down.

If at any time during the battery discharge the input power becomes available again, the input and the bypass

switchgear close and the rectifier begins to supply DC current to the converter and inverter. At this point, the

unit returns to Normal mode. Depending on the total load and the duration of the battery discharge, battery

current limit alarms may be seen for a short time due to the current required to recharge the battery.

7.3.1 PredictPulse Service Features

PredictPulse provides proactive monitoring, an online dashboard, mobile app with alarm status information and

a monthly report detailing the ongoing health of your Eaton 93E UPS. Features include:

lProactive monitoring that automatically analyzes the status of the Eaton 93E UPS 96 times every day (every

15 minutes). All health data gathered from the unit, current and historical, is analyzed at the Customer

Reliability Center (CRC). Algorithms and sophisticated analytics software is constantly scanning your UPS's

data for potential failures. Anomalies are escalated to a Software and Monitoring analyst or Technical

Support specialist. Critical events are remotely diagnosed to expedite repairs, including smart dispatch of

field technicians with probable cause and likely parts (avoiding return visits due to lack of required parts).

Through this service, the CRC can take pre-emptive, corrective action to ensure the highest level of

availability of your Eaton 93E UPS.

lEasy self-installation in minutes from a wizard installer or directly from the PXGMS card. PredictPulse uses

standard Eaton connectivity hardware, requiring no special software (devices only need to be connected to

a network).

lAbility to give an unlimited number of coworkers access to the real-time data and reports found in

PredictPulse’s online dashboard and mobile app. This allows you to collaborate and Eaton to notify the most

appropriate person responsible for a specific site or device.

lReal-time access to key performance information, alarms and trended health data about your Eaton 93E UPS

via the PredictPulse online dashboard. Depending on the model, the dashboard aggregates all subscribed

devices and provides detailed information about voltages, loads, energy savings, service levels, external

factors such as temperature and humidity, attached batteries, and system availability. All of these factors

contribute to the Relative Performance Index (RPI) score that allows you to compare your unit's health

relative to Eaton's optimum UPS operating levels.

lReal-time alarm events for all subscribed devices via the PredictPulse mobile app (Apple and Android). You

can track all alarms by device. As critical alarms occur, Eaton will acknowledge them so you know when

Eaton has diagnosed the alarm (and pending notification of resolution).

lA monthly summary report that delivers key performance information, alarms and trended health data about

your Eaton 93E UPS, based on the prior month’s data.

lA foundation based on CA Technologies’ leading Data Center Infrastructure Management (DCIM) software

application. This enables powerful reporting, analytics, security, and compatibility with hundreds of power

infrastructure devices.

7.3.2 Installing PredictPulse

A quick start guide and self-installation wizard tool are available at www.eaton.com/predictpulse. The latest

updates, installation tips and information on connecting PredictPulse are also available at that link. For

installation support or questions about PredictPulse, contact predictpulsesupport@eaton.com.

PredictPulse relies on a PXGMS card installed with the UPS to send one-way outbound SMTP e-mails to Eaton,

as well as an Environmental Monitoring Probe (EMP) for battery temperature/humidity monitoring. PredictPulse

is secure as Eaton never communicates through your firewall—it only listens for health data and alarm data—

and uses industry-standard security protocols. By using a common e-mail transport mechanism, you do not

have to open your network to proprietary or potentially unsecure protocols and transports. The PXGMS

Connectivity Card gathers information directly from the UPS and any external sensors that are attached, and

transmits that data every 15 minutes (or 96 times per day), enabling real-time monitoring and advanced virtual

preventive maintenance.

Chapter 8 UPS Maintenance

The components inside the UPS cabinet are secured to a sturdy metal frame. All repairable parts and

assemblies are located for easy removal, with very little disassembly. This design allows authorized service

personnel to perform routine maintenance and servicing quickly.

You must schedule periodic performance checks of your UPS system to keep it running properly. Regular

routine checks of operation and system parameters enable your system to function efficiently for many

trouble-free years.

8.1 Important Safety Instructions

Remember that your UPS system is designed to supply power EVEN WHEN DISCONNECTED FROM THE

UTILITY POWER. The UPS module interiors are unsafe until the DC power source is disconnected and the

electrolytic capacitors are discharged. After disconnecting the utility power and the DC power, authorized

service personnel should wait at least five minutes for capacitor bleedoff before attempting internal access to

the UPS module.

WARNING

lServicing and maintenance should be performed by qualified service personnel only.

lLETHAL VOLTAGE PRESENT. This unit should not be operated with the cabinet doors open or

protective panels removed. Do not make any assumptions about the electrical state of any

cabinet in the UPS system.

Each battery string is an energy source in itself. DO NOT ATTEMPT TO ACCESS ANY INTERNAL AREA OF

THE BATTERY STRING YOURSELF. VOLTAGES ARE ALWAYS PRESENT IN THE BATTERY STRING. If

you suspect that a battery string needs service, contact an Eaton service representative.

If the string requires service contact an Eaton service representative.

Observe these precautions when working on or around batteries:

lRemove watches, rings, or other metal objects.

lUse tools with insulated handles.

lWear rubber gloves and boots.

lDo not lay tools or metal parts on top of batteries.

lDisconnect the charging source prior to connecting or disconnecting terminals.

lDetermine if the battery is inadvertently grounded. If it is, remove the source of the ground. Contact with

any part of a grounded battery can result in electrical shock. The likelihood of such shock is reduced if such

grounds are removed during installation and maintenance.

lWhen replacing batteries, use the same number of sealed, lead-acid batteries.

lProper disposal of batteries is required. Refer to your local codes for disposal requirements.

lDo not dispose of batteries in a fire. Batteries may explode when exposed to flame.

lDo not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
