Setup and Start-up
Inspect the UPS for any signs of
obvious damage. If damage is visible,
do not proceed with the setup and call
our warranty support line for assitance
1-800-222-5877 menu option 3, email
[e-mail].
1. The UPS has 3 battery-
backed and surge-protected
receptacles and 3 surge-
protected-only receptacles.
Plug your critical equipment (such
as computer, monitors, etc.) into
the battery-backed receptacles
and your less-critical equipment
(such as printers and other less-
often used peripherals) into the
surge-only receptacles.
2. To protect your computer
network connection or
telephone,
use the network/telephone surge-
protection ports on the side. Use
the “IN” port to connect the line
from the wall jack and the “OUT”
port to connect to your device
port. Use of this feature is not
required for proper operation of
the UPS.
3. To use the USB communication,
plug the provided cable into the
port on the UPS and the other end
into an open USB port on your
computer. This allows unattended
shutdown of your computer
using either the built-in feature
within the Microsoft® Windows®
operating system or the Multilink®
Shutdown software located on the
CD that shipped with the UPS. Use
of this feature is not required for
proper operation of the UPS.
4. Start the UPS.
Plug the UPS input cord into the
wall outlet. To turn on the UPS,
press and hold the ON/OFF button
until you hear the UPS beep, then
release the button. The connected
equipment immediately receives
power and the UPS starts a short,
self system test (electronics and
battery check). When the unit
passes all self checks, only the
green LED should be lit indicating
normal operation.
While every precaution has been taken
to ensure that the battery is in good
condition, we recommend allowing the
UPS to charge the battery for at least
4 hours prior to providing full back-up
time protection for any utility-power
abnormality.
