Step 3: UPS output connection
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 4: Communication connection
Communication port:
USB port
RS-232 port
Intelligent slot
To allow for 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.

either SNMP or AS400 card in the UPS, it will provide advanced communication and monitoring
options.
