Step 2 - UPS output connection
For socket-type outputs, there are two kinds of outputs: programmable outlets and general
outlets. Please connect non-critical devices to the programmable outlets and critical devices
to the general outlets. During power failure, you may extend the backup time to critical
devices by setting shorter backup time for non-critical devices.

Step 3 - Communication connection
Communication ports:
USB port
To allow unattended UPS shutdown/start-up and status monitoring, connect the
communication cable one end to the USB/RS-232 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.
The UPS is equipped with intelligent slot perfect for either SNMP or AS400 card. When
installing either SNMP or AS400 card in the UPS, it will provide advanced communication
and monitoring options.
PS: USB port and RS-232 port can't work at the same time.
