Operating conditions
This product is an Uninterruptible
Power Supply (UPS) for computers
and their peripherals, television sets,
stereo systems and video recorders...
It must not be used to supply other
electrical equipment (lighting, heating,
household appliances, etc.).
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
6 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 connected to the filtered
outlets 7 that provides surge
protection (see figure B). The filtered
outlets are not backed up by battery
power in the event of a power outage.
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.
Operation

7 : Three filtered outlets.
8 : ON/OFF button for the battery
backup outlets.
9 : LED ON indicate that surge
protection is active on all six
outlets.
10 : Protection circuit breaker.

Battery charge: The UPS charges
the battery as soon as it is connected
to the AC outlet, whether button 8 is
pressed or not. When used for the
first time, the battery will only provide
its maximum autonomy after it has
been charged for 8 hours. It is
recommended that the UPS be
permanently connected to the AC
power supply to ensure the best
possible autonomy.
Filtered outlets 7 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
4 - MAU-00044/AB
button 8 .
Battery backup outlets 6 :
Equipment connected to these outlets
is supplied as soon as button 8 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 8 flashes).
AC-power disturbance: If AC
power is disturbed or fails, the UPS
continues to operate on battery
power. Button 8 flashes green.The
audio alarm beeps every five
seconds, then every two seconds
when the end of battery backup time
is near.
If the power outage lasts longer than
the battery backup time, the UPS
shuts down and must be restarted by
pressing button 8 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 8 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 8 .
Shutdown of the battery backup
outlets 6 : Press button 8 for more
than two seconds.
