IMPORTANT SAFETY INSTRUCTIONS  
SAVE THESE INSTRUCTIONS  
This manual contains important instructions for Models EX7/EX10/EX15/EXB10/EXB15 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 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 batteries discharge;  
c Pulsar contains batteries that should be  
disposed of or recycled in accordance with  
local applicable laws;  
cc ~CA:UaTlteIOrnNa:tidnog ncoutrrdeinstpsouspepolyf bsaytmtebroyl;or

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,  
c The UPS contains voltages which are  
potentially hazardous. All repairs should  
be performed by qualified service  
personnel only;  
v use tools with insulated handles,  
v wear rubber gloves, boots and safety  
glasses;

introduction  
other interconnection devices that are  
sensitive to electrical disturbances.  
Pulsar EX7, EX10 and EX15 add fault-  
tolerance to the utility supplying your  
sensitive equipment.  
Pulsar EX7, EX10 and EX15 are designed  
as compact units and feature very silent  
operation. They can be installed under a  
desk, and can also be installed in a rack  
(see "options").  
Pulsar EX7, EX10 and EX15 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 EX7, EX10 and EX15 On-Line  
technology provides maximum protection  
and availability of your workstations, server,  
and network communication devices.  
Pulsar EX7, EX10 and EX15 offer many  
functions and characteristics designed to  
simplify power management:  
In critical situations, count on MGE UPS  
SYSTEMS Pulsar EX7, EX10 and EX15  
uninterruptible power supplies (UPS). Their  
protection keeps your data intact and  
accessible.  
of Pulsar EX7, EX10 and EX15 using the  
EX Tuner configuration module. This module  
adapts Pulsar EX7, EX10 and EX15 to user  
preferences (battery test frequency, startup  
and shutdown sequences, setting of battery  
thresholds, etc.). Operation and monitoring  
are ensured by the UPS Manager 3.1  
module operating under Windows 3.1.  
EX Driver connects to the RS 232 port on  
the Pulsar EX7, EX10 and EX15 (see  
"communication" section for further details);  
c Solution-PacTM is a CD-ROM which  
contains all the tools needed to supervise  
your UPS.  
Pulsar EX7, EX10 and EX15 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.  
application of Pulsar EX7, EX10  
and EX15:  
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  
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  
c automatic battery test carried out  
periodically. In the event of a fault, a LED  
provides advance warning for battery  
replacement;  
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 Pulsar EX7, EX10 and EX15 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  
consequences of these disturbances on  
computer systems range from data losses to  
hardware damage (power supplies, hard  
disks).  
Pulsar EX7, EX10 and EX15 are specially  
designed to protect network servers and all

alarms to any SNMP supervisor.  
communication with the UPS from a simple  
Windows workstation. EX-Driver is  
compatible with Windows 3.1x and Windows  
95, for communication with the UPS via a  
serial connection for various needs:  
c personalization of the UPS operating  
mode: the EX-Tuner utility, can be used to  
change certain UPS operating parameters if  
the standard factory settings are not ideal for  
the operating conditions.  
It is possible to modify the output voltage,  
battery-test frequency, startup and shutdown  
sequences, operation of automatic by-pass,  
etc.;  
c UPS monitoring from a Windows  
workstation and system safety:  
EX-Driver, UPS Manager 3 software, can  
display the UPS status, warn the user if a  
problem arises, and provide automatic  
shutdown.  
Protection by UPS is only complete and  
effective if combined with powerful software  
functions which warn users and the operator  
of any power supply problem, automate  
system shutdown, supervise and remotely  
control the UPSs. MGE UPS SYSTEMS  
created Solution-PacTM for this purpose.  
Solution-PacTM combines all these functions  
in a single CD-ROM, usable in local or  
remote mode (SNMP), and covering the  
main network environments.  
Solution-PacTM is the ideal solution for  
protecting networks and multistation  
systems.  
Solution-PacTM on a single CD-ROM  
contains everything needed to safeguard  
one or more systems and to supervise one  
or more UPSs from a local or remote station.  
Solution-PacTM includes SNMP UM-Agent,  
UM-Client system shutdown software, and  
UM-Console supervision software.  
Solution-PacTM is a powerful and upgradable  
software tool which provides all the  
supervision, control and safety functions  
The many possibilities available include:  
v supervision of operating parameters  
through a graphic interface (display of  
battery charge level, remaining battery time  
and UPS load level). These values can be  
recorded periodically in a log file,  
v messages to the user in case of power
