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;

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 front panel LEDs signal all types of faults  
and alarms;

c Bar graph continuously indicates the  
battery charge level or the critical load power  
level;  
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  
(fire alarm, climate control fault, intrusion,  
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;  
c EX Driver software provides rapid startup  
of Pulsar EX20Rack and EX30Rack using  
the EX Tuner configuration module. This  
module adapts Pulsar EX20Rack and  
EX30Rack to user preferences (battery test
