Operating conditions

This product is an Uninterruptible
Power Supply (UPS) for computers
and their peripherals. It must not be
used to supply other electrical
equipment (lighting, heating,
household appliances, etc.).
Equipment such as television sets,
stereo systems and video recorders
may be connected to the filtered
outlets 8 only.

UPS connections

Connect the UPS 1 to the AC-
power system via a wall outlet with an
earth connector, using the supplied
cord 2 (see figure A).
Plug critical equipment (computer,
monitor, modem, etc.) into the outlets
9 providing battery backup power
and surge protection (see figure B),
taking care not to exceed the rated
current indicated in amperes.
Other devices (printer, scanner, fax,
etc.) can be connect to the filtered
outlets 8 that provide surge
protection (see figure B). The filtered
outlets are not backed up by battery
power in the event of a power outage.
Optional fax/modem connection:
A telephone, fax, modem or Ethernet
data line can be protected against
surges by connecting it to the
telephone outlet via the UPS. The
device cable is used between the
telephone outlet and the UPS, and
the supplied cable 3 is used
between the UPS and the device, as
indicated in figure C.
Optional COM connection:
The 500 and 675 VA devices can be
connected to the computer using the
special USB cable 6 supplied.
The software available on the CD-
ROM 7 (or downloadable from the
mgeups.com site) can be configured
to monitor the UPS and the supply of
power to the computer (see figures D
and F).
Follow the indicated procedure.
At the same time, register for the

Battery charge: The UPS charges
the battery as soon as it is connected
to the AC outlet, whether button 13
is pressed or not. When using the
UPS for the first time, it is advisable
to wait eight hours to fully-charge the
battery before connecting the
equipment to be protected.
The UPS can remain connected at
all times for continuous operation.
Filtered outlets 8 without
battery backup: Equipment
connected to these outlets is supplied
as soon as the AC cord 2 is
plugged in. They are not affected by
button 13 .
Battery backup outlets 9 :
Equipment connected to these outlets
is supplied as soon as button 13 is
pressed and turns green (see figure
E). These outlets can be turned on
even if the UPS is not connected to
AC power (button 13 flashes).
AC-power disturbance: If AC
power is disturbed or fails, the UPS
continues to operate on battery
power. Button 13 flashes green. In
normal mode, the audio alarm beeps
every ten seconds, then every three
seconds when the end of battery
backup time is near. In silent mode
(see the section on settings), the
audio alarm simply beeps once when
the UPS transfers to battery power.
If the power outage lasts longer than
the battery backup time, the UPS
shuts down and automatically restarts
when power is restored. Following a
complete discharge, a few hours are
required to recharge the battery back
to full backup time.
To save battery power, it is possible
to press button 13 to cut the supply
of power to the devices connected to
the battery backup outlets.
Surge protection: All outlets,
whether backed up or simply filtered,
include surge protection, whatever
the position of button 13 .
Shutdown of the battery backup
outlets 9 : Press button 13 for
more than two seconds.
