Chapter 1 SAFETY INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation and maintenance of the UPS and
batteries. Please read all instructions before operating the equipment and save this manual for future reference. The UPS
operates with mains, battery or bypass power. It contains components that carry high currents and voltages. The properly
installed enclosure is earthed and IP20 rated against electrical shock and foreign objects. However, the UPS is a sophisticated
power system and only qualified personnel is allowed to install and service the UPS.
WARNING
• Operations inside the UPS must be performed by a service engineer from the manufacturer or from an agent authorized by the
manufacturer.
• This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by AUTHORIZED SERVICE PERSONNEL
ONLY.There are NO USER SERVICEABLE PARTS inside the UPS.
WARNING
• The UPS is powered by its own energy source (batteries). The output terminals may be energised even when the UPS is
disconnected from an AC source. To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40 °C (104 °F). Do not
operate near water or excessive humidity (95 % maximum).The system is not intended for outdoor use.
• Ensure all AC and DC power sources are disconnected before performing installation or service. Power may come from multiple
sources.
• In parallel system, output terminals may be energised even when the UPS is turned off.
• Ensure system grounding/PE continuity when undertaking installation or service.
• Batteries can present a risk of electrical shock or burn from high short-circuit current.
• ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors. Attempting to alter wiring can cause
injury.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
• IMPORTANT: the battery may consist of multiple parallel strings, disconnect all strings before installation.

Eaton 93PR 500 kW UPS
User's and Installation Guide 2
CAUTION
• Installation or servicing should be performed by qualified service personnel knowledgeable of batteries and required
precautions. Keep unauthorized personnel away from batteries. Consider all warnings, cautions, and notes before installing or
replacing batteries. DO NOT DISCONNECT the batteries while the UPS is in Battery Mode.
• Replace batteries with the same number and type of batteries as originally installed in the UPS.
• Disconnect the charging source prior to connecting or disconnecting terminals.
• Determine if the battery is inadvertently grounded. If it is, remove the source of the ground. Contacting any part of a grounded
battery can cause a risk of electric shock. An electric shock is less likely if you disconnect the grounding connection before you
work on the batteries.
• Proper disposal of batteries is required. Refer to local codes for disposal requirements.
• Do not dispose of batteries in a fire. Batteries may explode when exposed to flame.
• Keep the UPS door closed and front panels installed to ensure proper cooling airflow and to protect personnel from dangerous
voltages inside the unit.

The user must follow the precautions and only perform the described operations. Any deviation from the instructions
could be dangerous to the user or cause accidental load loss.
WARNING
The user is not permitted to open any screws excluding connectivity plates and the MBS locking plate. Failure to recognise
the electrical hazards could prove fatal.
CAUTION
• The 93PR 500kW models are available as C2 UPS product which can be placed both in a residential and commercial/
industrial environment. When included in a residential environment, this product may cause radio interference, in which
case the user may be required to take additional measures.
• By standard, the 93PR 500kW models are category C3 UPS products, meant for all commercial and industrial
establishments.
1.4. Environment
The UPS must be installed according to the recommendations in this manual. Under no circumstances should the UPS
be installed in an airtight room, in the presence of flammable gases, or in an environment exceeding the specifications.
Excessive amount of dust in the operating environment of the UPS may cause damage or lead to malfunction. The UPS
should always be protected from the outside weather and sunshine. In order to maximize internal battery service life
time, the recommended operating temperature range is from +20 to +25 ºC.
WARNING
Hydrogen and oxygen gases are emitted from batteries into the surrounding atmosphere during charge, float charge, heavy
discharge, and overcharge. Explosive gas mixture may be created if the hydrogen concentration exceeds 4 % by volume in air.
Necessary air flow rate for ventilation of UPS location must be ensured.

Chapter 2 INTRODUCTION
Eaton 93PR 500kW UPS series uninterruptible power supply (UPS) is a true online, continuous-duty, transformerless,
double-conversion, three-phase modular system that supplies conditioned and uninterruptible AC power to critical load and
protects it from power failures.
Eaton 93PR 500kW UPS has flexible power scalability from 50 kVA to 4.0 MV, hot swappable modular and standard design,
high flexibility and applicability, market leading efficiency, availability and performance, very suitable to applications of micro
data center (MDC), small-middle-large data center, automation, medical etc. to protect power and customized power system
solution.
The UPS system is housed in two cabinet on parallel with safety shields behind the door for hazardous voltage protection.
Each UPS cabinet has a centralised system static bypass. The available static bypass rating is 500kW. The static bypass size is
chosen according to UPS system power. For example, if future requirement is to upgrade the UPS capacity, the UPS bypass
rating will have to be selected accordingly. In addition, the bypass ratings of all UPS cabinets in a parallel system need to be
matched.
Eaton 93PR 500kW UPS output power ratings are based on 50kW rated uninterruptible power modules (UPMs). A single UPS
cabinet can house one to ten UPM to get UPS power rating requirement.
A UPM includes a rectifier, inverter, battery converter, and independent controls. The UPM is hot swappable (Hot Swap) Each
UPM is able to operate independently from the other power modules.
NOTE
Startup and operational checks must be performed by an authorized Eaton Customer Service Engineer, or the warranty terms
specified in Chapter 9 Warranty become void. This service is offered as part of the sales contract for the UPS. Contact service in
advance (usually a two-week notice is required) to reserve a preferred startup date.

2.1. Looking Inside the UPS System
The system level static bypass in the 93PR 500kW UPS UPS cabinet determines the attainable output power of the
UPS. The static bypass line consists of static switch and a backfeed protection isolation device connected in series. In
addition, there is a system level control unit that constantly monitors the power delivered through the bypass line or to
the input of the UPS. Transfers to static bypass are seamless and performed automatically by the system as needed,
for example, in case of an extended system overload.
Each UPM power module includes a rectifier, battery converter, inverter and independent controls. The UPM is hot
swappable (Hot Swap) Each UPM is able to operate and share the load independently, despite the status of the other
UPMs.
In addition, the system can have a internal maintenance bypass switch as default.
UPS includes a 600 kW rated static bypass section, maximum ten internal paralleled UPM modules, These units do not
include internal batteries. Figure
