3 Introduction to Eaton UPS
33..11 AAbboouutt tthhee EEaattoonn UUPPSS
Figure 1. Eaton 93PM G2 UPS
The Eaton® 93PM G2 uninterruptible power supply (UPS) is a true online, continuous-duty,
transformerless, double-conversion, solid-state, three-phase system that supplies conditioned and
uninterruptible AC power to critical load and protects it from power failures.
The UPS 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 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 require 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 protection
against hazardous voltage. Each UPS cabinet has a centralized system static bypass.
Eaton 93PM G2 output power ratings are based on 50 kVA and 60 kVA rated uninterruptible power
modules (UPMs) installed in 200/240 kVA or 300/360 kVA UPS frames. A single UPS cabinet can house
from one to four or six UPMs.
See Section 3.9 Basic system configurations for a full list of available configurations.
EATON 93PM G2 UPS USER’S AND INSTALLATION GUIDE P-164000956 -February 2021 www.eaton.eu 1166

A UPM includes a rectifier, inverter, DC/DC converter, and independent controls. Each UPM is able to
operate independently from the other power modules.
NOTE: Startup and operational checks must be done by an authorized Eaton Customer Service Engineer
or by other qualified service personnel authorized by Eaton, or the terms specified in the Warranty (see
10.1 General information about 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.
33..22 LLooookkiinngg iinnssiiddee tthhee UUPPSS ssyysstteemm
The system level static bypass in the Eaton 93PM G2 UPS cabinet determines the attainable output
power of the UPS. The static bypass line consists of static switch, a back feed protection isolation device
and fuses designed to protect the static switch. The back feed protection and bypass fuses are located in
series with the static switch. 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 includes a rectifier, DC/DC converter, inverter and independent controls. Each UPM is able to
operate and share the load independently, despite the status of the other UPMs.
If utility power is interrupted or falls outside the parameters specified in Section 9.1 About technical data,
the UPS uses a DC supply (i.e. battery, super capacitor, etc.) 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.

The UPS operating modes are as follows:
Operating mode Description
Normal operating modes:
Double conversion mode Critical load is supplied by the inverter, which
derives its power from rectified utility AC power. In
this mode, the DC/DC converter also provides
charging current for the DC source, if needed.
Variable Module Management System (VMMS)
mode Critical load is supplied by the inverter. The
inverter derives its power from rectified utility AC
power, identically to double conversion mode. In
the VMMS mode, the 93PM G2 UPS system is
able to optimize the load level per power module:
the operating efficiency is significantly improved
when operating load is below 50 % of UPS
capacity. The UPS system will automatically place
the redundant power modules to suspended mode.
In case of any anomalies in utility or a sudden load
increase, the suspended power modules are able
to transfer to online mode with less than 2 ms
transition time.
Energy Saver System (ESS) mode Critical load is supported securely by utility power
through the static bypass switch with double
conversion available on-demand with typically less
than a 2 ms transition time, should any abnormal
condition be detected in the utility. Operating the
UPS in the ESS mode increases system efficiency
up to 99 %, allowing significant savings in energy
losses without compromising system reliability
Other operating modes:
EATON 93PM G2 UPS USER’S AND INSTALLATION GUIDE P-164000956 -February 2021 www.eaton.eu 1199

Stored energy mode Energy is drawn from a DC backup power source
and converted to AC power by the UPS inverter.
Most commonly VRLA batteries are introduced to
the system for this purpose, and the mode of
operation is called the battery mode
Bypass mode Critical load is supported directly by utility power
through the UPS static switch.
33..33..11 oorrmmaall ooppeerraattiinngg mmooddeess
This is a UPS with several normal operating modes: Double conversion, Double conversion with VMMS,
and ESS with double conversion on-demand. During normal UPS operation, power for the system is
derived from a utility input source. Unit Online, Unit Online VMMS, or Unit Online ESS is
displayed on the front panel, indicating that the incoming power is within voltage and frequency
acceptance windows.
