Connecting your equipment and first usage
Step 1. Connect the UPS to a grounded AC power outlet.
Step 2. UPS Output Connection: simply connect
devices to the outlets.
Step 3. Turn on the UPS: Press the ON/Mute button
on the front panel for two seconds to power
on the UPS. The battery charges fully during
the first 5 hours of normal operation. Do not
expect full battery run capability during this
initial charge period.
Step 4. Plug your PC or peripheral equipment (monitor,
tv, scanner, fax, speakers etc.) into the power
outlets of the UPS
(these will provide emergency
battery backup power during power blackouts as
well as surge protection from surges and spikes).
Step 5. Communication connection: To allow for
unattended UPS shutdown/start-up and
status monitoring,
communication cable on one end to the USB
port and the other to the communication port
of your PC. With the monitoring software
installed, you can schedule UPS shutdown/
start-up and monitor UPS status through PC.
