Thank you for your purchase of the Esprit rack
"UPS" from MGE. The Esprit "UPS" will provide
many years of, trouble-free power protection for
critical high availability servers and other devices.
Please read this manual fully, to familiarize yourself
with the safety instructions and Esprit features.

MGE UPS Systems

MGE, one of the largest UPS manufacturers in
the world, has a power protection solution for
every power problem. Our product range includes
UPSs from 250 VA to over 4.5 MVA in single and
three phase configurations. Other products
include Power Management Software, DC to AC
inverters, line conditioners and isolation
transformers. Contact your sales representative
today for additional information about MGE’s
other fine products.

Why the Need for Uninterruptible
Power?

Servers and other electronic devices do not store
sufficient energy to overcome the power outages
and short interruptions that occur on a daily basis.
Any interruption of the utility power may 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 if the utility power is lost or a short

outage

occurs. In addition, the Esprit UPS provides

surge
protection from indirect lightning strikes, power
surges and short high voltage transients (spikes)
created by machinery or other common equip­ment.

Theory of Operation

Esprit normally operates in the bypass mode.
Surge suppression and filtering are also provided
in this mode.

The UPS instantly transfers the load to the battery
when a power failure occurs. If the power returns
before the battery is exhausted, the operation
returns to normal and the batter y is recharged.

The Esprit UPS is comprised of three major
systems: the inverter, the battery/battery charger
and the bypass.

All logic and supervision in the UPS is 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 converted into a pseudo-sine
wave by a pulse width modulated (PWM) inverter.
This unique MGE technique, eliminates all bulky
60 HZ components, reduces heat, and greatly
enhances reliability.

Battery

The battery provides the energy source for back-up
when a power failure occurs. The battery is a
recombinant, sealed, lead acid-type battery which
provides the high current required for UPS use
and long life. It requires no addition of water during
its life.

Battery Charger

The battery charger maintains the battery. The
battery charger converts 120 volt AC utility power
to filtered and regulated DC current specific for
battery charging.

Bypass

The bypass is the electro-mechanical hardware
providing a transfer to or from the in verter. This is
done rapidly and synchronized to the utility power
sine wave in order to pro vide contin uity to the critical
device and not cause a re-boot.

3A. Storing the UPS and Recharging the Battery

Always store the equipment in its original packaging.
The battery is of the sealed lead-acid type. Battery recharge requires that the battery module be

plugged into an energized NEMA 5-15 receptacle for 6-8 hours. The battery may be charged in the
box by pulling the AC cord out through the bottom.

Battery storage or prolonged shutdown should never exceed 6 months or 68°F (20°C), for a
battery initially at 100% charge. The battery warranty is void if the 6 month recharge interval
is not adhered to.

3B. Unpacking the UPS

It is recommended that the equipment be unpacked in an area close to its installation location.

Caution:

The UPS and extended batteries weigh up to 75 pounds each.

Two people are required to lift the unit.

Remove the Solution-P ac CD, RS232 cable, and USB cable from the bo x and set aside f or later use .
Fold the box flaps outw ard. Gently rotate the box on its side and slide the unit out of the box. Gently
rotate the unit upright and then remove the packing material. Save packaging for future shipment
of UPS to MGE for recycling.

3C. Placement of the UPS

Choose a location out of direct sunlight with adequate ventilation. The operating ambient temperature
range is 32° to 104°F (0° to 40°C). Temperatures above 77°F (25°C) should be avoided as battery
life is reduced.

Ensure that there is clearance around the intake vents in the front of the UPS and that the rear is unob­structed. Six inches of clearance at the rear of the unit is required. Units may be placed vertically or hor­izontally with zero clearance. Use the supplied stabilizing feet when vertically mounting the UPS and/or
extended battery.

Rack Mounting

Optional rack mounting hardware is available for rack mounting. Instructions for their use are included
in the rack kit. See Figure 2a.

3D. Optional Accessories

The following accessories are available for use with your equipment. Refer to each accessories'
manual for full installation, operation and maintenance instructions.

3E. Connecting the Optional Extended Battery

Plug the DC battery cable into the UPS module as shown in Figure 2a. The cable plug is keyed,
so make sure to align the plug properly to the receptacle. Do not force the cable on, nor attempt to
reverse the connection. To do so, will damage the equipment and void the warranty. Plug the AC
line cord into an AC line receptacle. See Figure 3f.

3F. Disconnecting the UPS & Battery to Take Out of Service

Turn off the UPS module by depressing the “Off” red button if the “inverter on” or "utility power
present" (bottom LED) is lit. Unplug the AC line cord for the battery module. Unplug the DC battery
cord. For extended batteries unplug AC line cord and DC battery cord.

3G. Connecting to the Communication Ports

If you plan to utilize Solution-P ac HID ("human interface de vice" protocol), read the Solution-P ac HID
manual on the Solution-Pac CD for a full description of its features.

To connect to your computer, you will need the RS232 serial por t or a USB (Universal Serial Bus)
port. The connection will be made between your computer’s serial or USB por t and the serial or
USB port on the rear of the UPS module as shown in Figure 3d. Cables are supplied for this purpose.

A slide switch is provided for either RS232 or USB communication. The slide switch (shown in

Figure 3d)

is preset for RS232. Push the switch down for USB communication.

If communication does not operate, check the position of the slide switch.

The RS232 port also contains two low voltage (24 VDC)/low current (5MA) contact closures. See

Figure 3d

below. To use these an optional cable is available. These can be used by AS/400

computers or for special uses.

The transistor resistance is 27 ohms and the maximum current allowed is 140mA AC or DC with
ambient temperature of up to 40°C.

In order to get a "logic low" you have to limit the current to: logic low voltage required divided
by 27, logic low voltage = 0.5V. I max = 0.5/27=0.0185A=18mA.

If you intend to use other forms of communication, an optional Multi-slot Communication is available
that will convert the RS232 serial commands into the following formats:

◗ Ethernet, SNMP ◗ J-Bus/RS422 ◗ High voltage/current relay contacts

Figure 3b. Communication Ports (USB and RS232 serial port)

3H. Connecting the UPS to the Utility

Plug the AC line cord of the UPS module into an AC 2-pole, 3-wire grounded receptacle for models
3 and 4. There should be no other loads on this branch circuit. To do so may result in a circuit
overload. Refer to National Electrical Code (NEC) specifications for requirements in your area or
ask your electrician.

If desired, the UPS can be set up to operate at a known, fixed frequency regardless of the
detected utility frequency. Fixed-frequency operation is often desirable in installations that
make use of cold-start capability. Discussion on this is in the Advanced Configuration Section
(section 6) of this manual.

If utility power is present and within specifications, your UPS will start up in bypass mode. Power
will be supplied to your computer loads and will be protected from a utility loss. The utility power
present, green indicator " ", will be lit.

If utility power is not present, your UPS will start on battery until utility power is restored. No
diagnostics will be performed in this case.

The "Fault Detected" LED turns on and acts as described above for ANY system alar m,
including those that have their own status indicators (e.g. overload, replace batter y).

Button Operation

There are 3 buttons present on the front panel:

◗ The grey, " " top button controls the audible alarm and alarm/fault handling.
◗ The green, " " center button turns the UPS on.

◗ The red " ", bottom button turns the UPS off.

The internal microprocessor can directly read the state of the top (alarm silence) and bottom (power
off) buttons. The UPS is capable of distinguishing between a “short” and “long” depression and can
perform different actions based on how long a button or combination of buttons is depressed. A
“short” button press is defined as pressing and releasing a button within a 2-second time frame. A
“long” button press is recognized if a button is pressed and held for more than 2 seconds.

When a button is pressed, the UPS responds by beeping the horn. If the button is held down longer
than 2 seconds the UPS responds by beeping the horn again. The action assigned to a short button
press is carried out AFTER the button is released. Actions assigned to a long button press are carried
out immediately after the 2-second timeout, even if the button is not released after this time.

The UPS is capable of decoding six distinct “button states”:

1. Short Top button press: Silences the alarm beeper if it is active. If a new alarm/fault is

detected after a silence operation, the beeper will be re-activated to issue the new alert. This
button sequence can be thought of as an "alarm/fault acknowledge" function. By pressing it,
the user acknowledges the presence of the then-active system alarms. After an acknowledge
sequence, any new alarms that occur will be brought to the user's attention by re-activating the
alert beeper.

2. Long Top button press: Clears all active alarms and attempts to re-start the UPS on utility

power. If the UPS is already operating on utility power, or operating on inverter because utility

power is not present or not usable, then the alarms will be cleared but the restart-on-utility
request will be ignored. If the condition(s) that caused an alarm persist after alarm(s) are
cleared, the UPS will re-issue the alarm after a short delay.

3. Short Bottom button press: No UPS activity is associated with this button combination.

4. Long Bottom button press: Powers down the UPS. This is the "off switch". When the UPS

is powered down, neither utility or inver ter power is provided to the load.

5. Short Top + Bottom button press: The UPS will perform a battery testIF the UPS is running

on Utility power, and the batter y is at least 80% charged (charger indicator on). If these two
conditions are not met, the test will be postponed until they are met.

6. Long Top + Bottom button press: The UPS will enter configuration mode. In this mode,

various operational parameters may be changed b y the user. To exit configuration mode, press
the top and bottom buttons again.

Although six button states are detectable, not every button combination has an assigned task. button
states/combinations that have no assigned task will simply be ignored.

The “Utility Power Present” does NOT reflect the state of the UPS output. If, for example,
the UPS has shut down due to an output overload, the Utility Power Present LED may be
solidly ON but the UPS output could be turned off (due to the overload).

6. Advanced Configuration890-=qwertyuio

Esprit Front Panel Configuration Mode Usage and Instructions
For advanced users only!

The Esprit UPS is shipped from the factory with a configuration that is suitable for most applications.
However, there are some circumstances where modification of the UPS operating parameters is
required. A special configuration mode, accessible from the front panel, has been provided for this
purpose. This section of the manual describes how to use the front panel configuration mode and
describes the UPS parameters that can be changed by the user.

Caution: Configuration mode can only be entered when the Esprit is operating on utility
power. Attempts to enter configuration mode when the UPS is operating on battery
power will be ignored.

Caution: When the Esprit is in configuration mode, transfers to battery power are inhibited.
The load connected to the UPS will not be protected while the Esprit is in this mode.
Normal UPS operation will resume upon exit from configuration mode.

6A. Entering/Exiting Configuration Mode

The Esprit front panel configuration mode is entered by simultaneously depressing the top (Alarm
silence) and bottom (Pow er OFF) b uttons for approximately 1-2 seconds. The Esprit will acknowledge
entry into configuration mode by sounding the buzzer and slowly flashing the AC PRESENT indicator.
The AC PRESENT indicator blinks slowly during the time that the Esprit is in configuration mode.

To exit configuration mode, press and hold both top and bottom buttons again. The AC
PRESENT indicator will stop flashing, and the remaining indicators will resume their normal function.
Any changes to the Esprit configuration made by the user will be permanently saved.

The Esprit incorporates a timer that automatically terminates configuration mode if no activity is
detected for 30 seconds. This feature prev ents the unit from remaining in the vulner ab le offline state
for a long period if the configuration mode is accidentally entered.

6B. Using Configuration Mode

When configuration mode is activated, the usage of the front panel status indicators changes. The
top 4 indicators (GENERAL FAULT, BATTERY FAULT, BATTERY CHARGING, and
OVERLOAD) are no w used to indicate the internal feature being vie w ed or modified. The AC PRESENT
indicator blinks slowly to indicate that the Esprit is in configuration mode. The
bottom-most ON BATTERY indicator shows the state (on/enabled or off/disabled) of the currently
active feature.

In configuration mode, the topmost button (Alarm silence) is used to advance to the next
configuration setting. The top 4 indicators, which light in unique patterns to indicate which option is
being viewed/modified, cycle forw ard each time the top b utton is pressed. The bottom button (power off)
is used to toggle the current option ON or OFF. The ON BATTERY indicator toggles on and off each
time the bottom button is pressed.

6—1

6—2

It is possible to cycle backward through the configuration options by pressing and holding the top
button. A given option setting can be forced to its factory default state by pressing and
holding the bottom button.

The middle (Power ON) button is not used in configuration mode.
To leave configuration mode, simultaneously depress and hold in both the top and bottom

buttons until the buzzer sounds and the AC PRESENT indicator stops flashing. Any changes made
to the Esprit configuration will now be permanently saved.

6C. Configuration Options

The table below lists the options that can be changed by the user in configuration mode, and shows

Options 5, 6 – Input Voltage Tolerance

Use these two option switches to select the Esprit’ s sensitivity to low/high input voltage conditions .
The Esprit will switch to battery power when the utility voltage falls outside the range selected.
The percentages shown in the table below are subtracted/added to the nominal voltage setting
as set by options 4, 5. The factory setting is 5=OFF, 6=OFF which selects the –15/+10% range.

) = Option On/illuminated ( — ) = Option Off/dark

Do not select the "Custom" setting (Option 5 & 6 both ON) unless you are instructed to do so
by MGE service.

Option 7 – Test Alarm

The normal state of this option is OFF. Turning it on will instruct the Esprit to issue a "User Test
Fault". This condition does NOT affect the UPS operation in any way, but it does close the Low
Battery contact on the DB9 communication port, and activates the FAULT indicator and audible
alarm (pattern shor t-shor t-long). You can use this option switch to test hardware connected to
the Low Battery contact without actually running the Esprit batter y down.

To clear the User Test Fault, set this option to OFF, or follow the "Alarm Clear" procedure. Press
and hold the top button.

Option 8 – Limit run time on battery power

The normal setting for this option is OFF, which allows the UPS to operate on battery for the
maximum time possible. The Esprit run time on battery is limited only by the capacity of it’s battery
system and the battery state of charge.

If Option 8 is turned on, the Esprit will run a maximum of 15 minutes on battery power before
turning itself off. Actual run time may be less, depending on size of battery system and load.

Option 9 – Cold Start (allow UPS to run on battery power on startup)

When Option 9 is turned ON (factory setting), the UPS is allowed to start up on battery power
if the AC input voltage is not present or not of satisfactor y quality. The ability to run on battery
power immediately upon startup is known as "cold start" capability.

If this option is turned OFF, the UPS will start up with its output OFF if input AC is not present or usable.
The output will not be turned on until input AC is present and usable. Once the UPS turns on it’s
output, a subsequent loss/disturbance of input AC will cause the UPS to run on battery power as usual.

6—5

Option 10 – Automatic UPS restart after Low Battery shutdown

The factory setting for this option is ON, which allows the UPS to automatically turn its
output back on following a Low Batter y shutdown once input AC is present. This setting is the
usual one for applications where the UPS is connected to automated or unattended
equipment that is capable of restarting itself without direct human intervention.

If the load connected to the UPS requires special attention when it is powered up, this option
should be turned OFF. When Auto Restart is turned off, the UPS output will stay turned off until
it is manually restarted by pressing and holding the top silence/restart button on the front panel.

Option 11 – Automatic UPS mode

The default setting for Option 11 is ON, which allows the Esprit to act like a typical UPS. The
UPS will automatically switch from utility to backup power as needed.

If this option is turned off, the Esprit acts like a line conditioner. The battery backup
system is disabled. If the input utility power is acceptable, the Esprit will pass it through to the
load. If the input power is unacceptably low or high, the load power is removed. The Esprit will
NOT operate on battery power if Option 11 is turned off!

Option 12 – Automatic Frequency Detect

When this option is set the factory default ON setting, the Esprit will analyze the input power
when it is turned on, and configure itself to operate at the proper frequency (50 or 60 Hz). If
utility power is not present when the Esprit is turned on, it will configure itself based on the
frequency setting in place when the unit was last turned off (see option 13 setting).

If this option is turned OFF, the Esprit will configure itself to operate using a utility power
frequency set by Option 13. Power-up input AC frequency analysis is not performed.

Option 13 – Operating Frequency selection

This option setting is only effective if Option 12, Automatic Frequency Detect is turned off. If
Option 12 is turned off, this option (13) setting can be used to select the Esprit’s nominal oper­ating frequency. If this option is OFF, 50 Hz operation is selected. If ON, 60 Hz
operation is selected.

The factory setting for this option is ON, selecting 60 Hz operation at startup. Note,
however, that the setting of this option is overwritten by the UPS logic if option 12 (Automatic
Frequency Detect) is enabled. If the Espr it is powered up from a 50 Hz source with option 12
enabled, the setting of this option (13) will be forced to OFF.

Option 14 – Communication Mode Selection

This option should be left in it’s factor y-standard OFF setting unless you are instructed to turn
it ON by MGE Service. If this option is inadvertently turned ON, the Esprit may be
rendered incapable of operating with UPS monitoring and control software, including MGE’s
Solution-Pac software.

6—6

Option 15 – Power-On Inverter Test (POIT)

When this option is set to the factory default ON setting, the Esprit will perform a short
battery/inverter test shortly after it is tur ned on. This test is only performed only if the UPS is
able to power up the load from utility power first.If the POIT is enabled, the UPS will power up
the load from utility power, then briefly switch to battery power approximately
5-7 seconds after it is powered up. The UPS runs on battery for only 3-5 seconds, so no
significant drain on the battery will occur.

The POIT is disabled if this option is turned OFF. The setting of this option has no effect on the
scheduling and execution of the monthly inverter/battery test, which runs less
frequently than the POIT but is considerably more exhaustive.

7. Service & Maintenance

7A. Maintenance

Clean the UPS with a dry cloth after turning off all power to the UPS and switching off the power
switch.

The UPS performs monthly automatic battery tests. Howev er , it is recommended that a 6 month test
be performed on the UPS for battery condition. Perform all tests off peak hours with applications
shut down.

1.Turn off power to the UPS via the branch circuit breaker to the UPS. It is not recommended
to disconnect the plug from the UPS to the utility power due to disconnection of the safety
ground.

2.Allow the UPS to run on batter y power for 1 minute. Monitor the UPS for any fault LEDs and
if none are observed, return power to UPS and log results below in the maintenance log. If
battery fault LED is lit, call for service.
