IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions for Models EX20Rack / EX30Rack / EXB20/30 that should be
followed during installation and maintenance of the UPS batteries.
c This equipment can be operated by any
individual, with no previous training;
c CAUTION: Risk of electric shock, even
with unit disconnected from AC power
source. Hazardous voltage still may be
present through operation from battery.
The battery supply should be disconnected
at the plus and minus terminals using the
quick disconnect connectors of the battery
when maintenance or service work inside
the UPS is necessary.
c The UPS contains voltages which are
potentially hazardous. All repairs should
be performed by qualified service
personnel only;
c do not attempt to power the UPS from
any receptacle other than a 2-pole 3-wire
grounded receptacle;
c the AC power receptacle should be near
the equipment and easily accessible. To
isolate Pulsar from AC input, remove the
input power cord from the AC power
receptacle;
c if Pulsar is to be stored for a long time, it
is recommended to recharge the batteries
(by connecting AC power source to Pulsar,
switch "ON" or "OFF"), once a month for 24
hours to avoid a full battery discharge;
c Pulsar contains batteries that should be
disposed of or recycled in accordance with
local applicable laws;
c CAUTION: do not dispose of battery or
batteries in a fire. The battery may explode;
c CAUTION: do not open or mutilate the
battery or batteries, released electrolyte is
harmful to the skin and eyes. It may be toxic;
c CAUTION: a battery can present a risk of
electric shock and high short circuit current.
The following precautions should be
observed when working with batteries:
v remove watches, rings or other metal
objects,
v use tools with insulated handles,
v wear rubber gloves, boots and safety
glasses;
c prior to installation, store Pulsar in a dry
location;
c please dispose of the packaging in
c storage temperatures must be between
–4°F (-20°C) and +113°F (+45°C);
c servicing of batteries should be performed
or supervised by personnel knowledgeable
of batteries and the required precautions.
Keep unauthorized personnel away from
batteries;
accordance with applicable laws.
c do not place Pulsar near water or in
environment of excessive humidity;
c do not allow liquids or any foreign objects
to get inside Pulsar;
c do not block air vents in front or back of
c when replacing the batteries, use the
same number and the following type of
batteries:
v Pulsar EX20Rack: 8 x 12V - 7.2Ah,
v Pulsar EX30Rack: 8 x 12V - 7.2Ah;
c ~ : alternating current supply symbol;
Pulsar;
c do not plug household appliances such as
hair dryers to Pulsar receptacles;
c do not place Pulsar in direct sunlight or
close to a heat-emitting source;

introduction
In critical situations, count on MGE UPS
SYSTEMS Pulsar EX20Rack and
from atmospheric phenomena, to nearby
devices generating interference such as
elevators, photocopy machines and machine
tools, not to mention human errors, like the
accidental pulling out of power cords or
tripping of circuit breakers. The
consequences of these disturbances on
computer systems range from data losses to
hardware damage (power supplies, hard
disks).
Pulsar EX20Rack and EX30Rack are
specially designed to protect network
servers and all other interconnection devices
that are sensitive to electrical disturbances.
Pulsar EX20Rack and EX30Rack add fault-
tolerance to the utility supplying your
sensitive equipment.
Pulsar EX20Rack and EX30Rack are
designed as compact units and feature very
quiet operation.
Pulsar EX20Rack and EX30Rack provide a
stable supply of clean power, long back-up
time during a utility outage (see table) and
vast information and control possibilities
according to the configuration selected.
Pulsar EX20Rack and EX30Rack On-Line
technology provides maximum protection
and availability of workstations, servers, and
network communication devices.
Pulsar EX20Rack and EX30Rack offer
many functions and characteristics designed
to simplify power management:
c automatic battery test carried out
periodically. In the event of a fault, a LED
provides advance warning for battery
replacement;
EX30Rack uninterruptible power supplies
(UPS). Their protection keeps your data
intact and accessible.
Pulsar EX20Rack and EX30Rack UPSs
ensure top quality power around the clock,
and continue operations during power
failures. An intelligent microprocessor
detects any operating anomalies of the UPS
and triggers an alarm if corrective action is
necessary.
In addition to the high-technology aspect of
these UPSs, you can count on backup from
our staff, a team of specialists, around the
corner from you, throughout the world. It’s
no accident that MGE UPS SYSTEMS is the
world leader in UPS protection. The UPS
provides power factor correction to reduce
harmonic distortion and current created by
non-linear critical loads from polluting the
incoming AC line.

mode of operation in which the critical load
is continuously supplied by the inverter and
protected from all forms of power line
disturbances:
uses of Pulsar EX20Rack and
EX30Rack:
Network servers and interconnection
devices are very sensitive to electrical
disturbances of all types, including outages,
voltage sags, brownouts, spikes, etc. The
origins of the disturbances also vary, ranging

c Bar graph continuously indicates the
battery charge level or the critical load power

c UM Sensor environment measurement
unit: compatible with SNMP or Solution
PacTM, this unit measures the temperature
and the relative humidity in the room where
the Pulsar is installed. Eight relay contacts
are provided to transmit signals to an
administration platform, in the form of
voltage-free contacts to enable monitoring of

etc.);
additional communications
options:
c SNMP administration: MGE has the
most complete offering for the administration
of a group of UPSs using the SNMP protocol
with different network-connection modules
(SNMP card or proxy software), supervision
modules (application for NMS platforms
such as HP OpenView or C.A. UNICENTER
TNG) and a file-closing module (UM Client).
c SNMP card: this card, inserted into your
unit, can establish a direct Ethernet network
connection for your UPS. It can then be
temporarily managed using SNMP or the
various software modules of Solution-Pac.
The MGE UPS SYSTEMS offering complies
with RFC 1628 specifications (IETF) and
was certified by the InterWorking Labs
during the Test Summit in June 1994;
c status information card: this option
provides you with 5 voltage-free contacts: on
battery, on by-pass, low battery, load on
UPS. This card can be used with the UPS
driver of IBM AS/400.
c Pulsar EX20Rack and EX30Rack are
environment friendly: all components are
recyclable and an electronic power-saver
device reduces power consumption if the
UPS is not active for a period exceeding 5
minutes while on battery back-up;
