Instructions for Operation
CAUTION: Always turn off all power to computer prior to making any Ellipse connections.
See Quick Start Guide for connection details.
Set Up
1. Unpack UPS and accessories from shipping carton.
2. Connect input cord to a properly sized AC outlet.
3. Connect critical devices (computer, monitor, modem) on battery-backed up outlets keeping
load within UPS VA indicated rear label limits.
4. Peripherals can be plugged into surge filtered outlets or programmable outlets if you have
the Ellipse 1200. See PowerShare programmable outlets instructions in Solution Pac.
5. Connect the fax modem or network surge suppressor and USB or RS232 cable (supplied).
6. Switch on the UPS and allow to recharge for 8 hours for full battery capacity.
Software
Download Solution Pac software from the internet at: www.mgeups.com, "download
area", or request software through mail by checking the "request software" box on the
warranty card. You may register your new UPS with MGE while on-line or mail in the
warranty card.

replace battery.
Notes:
1. You do not have to switch on the UPS for the batteries to remain charged.
2. If the utility power failure exceeds the battery back-up time, Pulsar Ellipse shuts off to
prevent excessive battery discharge and will re-start as soon as power returns.
3. The overload breaker (see Quick Start Guide) trips off during a severe overload. If this
occurs, unplug excess loads and reset circuit breaker by pressing its reset button.
4. Do not connect non-computer type loads or laser printers to battery backed up
outlets.

Introduction
Thank you for your purchase of the Ellipse
"UPS" from MGE. The Ellipse "UPS" will
provide many years of accurate, trouble-free
power protection for your PC and/or other
device(s). Please read this manual fully, to
familiarize yourself with the safety and many
other features of the Ellipse product.

Why the Need for Uninterruptible Power?
PCs and other electronic devices, due to
their design, are subject to the effects of
power outages or short interruptions. They
do not store sufficient energy to overcome
outages or short interruptions and these
events occur on a daily basis. Any
interruption of the utility power will stop the
operation of a computer and cause loss of
data, potential hardware damage and
inconvenience.
A "UPS" is an uninterruptible power supply.
The UPS has an internal battery to provide
power back-up when the utility power is lost
or a short outage occurs. In addition, the
Ellipse UPS provides surge protection from
indirect lightning strikes, power surges and
short high voltage transients (spikes)
created by machinery or common office
equipment. A fax/modem (with cable) or
network suppressor is provided with every
MGE Ellipse UPS to also protect the
incoming data line to the PC.
Theory of Operation
Ellipse is an off-line or stand-by UPS which
normally operates in the bypass mode.
Surge suppression and filtering are also
provided in this mode.
The UPS transfers the load quickly to the
battery when a power failure occurs. If the
power returns before the battery is
exhausted, the operation returns to normal
and the battery is recharged.
The Ellipse UPS is comprised of three major
systems: the inverter, the battery charger/
battery and the bypass.
All logic and supervision in the UPS are
provided by a state-of-the-art micro-
controller.
Inverter
The inverter is the heart of the UPS and
inverts direct current (DC) from the battery
into alternating current (AC) at 120 volts.
The DC voltage from the batteries is
switched on and off at a high frequency and
transformed to a higher voltage (DC to DC
conversion). After conversion, the high
voltage is converted into a pseudo-sine wave
by a pulse width modulated (PWM) inverter
to 120 volts AC RMS. This unique MGE
technique, eliminates all bulky 60 HZ
components and reduces size, heat, and
greatly enhances reliability.
Battery Charger/Battery
The battery charger maintains the battery
and the battery provides the source of back-
up energy when a power failure occurs. The
battery charger converts 120 volt AC utility
power to filtered and regulated DC specific
for battery charging. The battery is a
recombinant, sealed, lead acid-type which
provides the high current required for UPS
use and long life. It requires no additions of
water during its life.
Bypass
The bypass is the electro-mechanical
hardware providing a transfer to or from the
inverter. This is done rapidly and
synchronized to the utility power sine wave
in order to provide continuity to the PC and
not cause a re-boot.
