2-4. Setup The UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension
cords.
Step 2: UPS output connection
There 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 RS-232 port Intelligent slot
To allow for unattended UPS shutdown/start-up and status monitoring, connect one end of
communication cable 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.
Step 4: Network connection
Network/Fax/Phone surge port
Connect a single modem/phone/fax line into surge-
protected “IN” outlet on t
he back panel of
the UPS unit. Connect from “OUT” outlet to the
equipment with another modem/fax/phone line
cable.
Step 5: Disable and enable EPO function
This UPS is equipped with EPO function. By default, the UPS is delivered from factory with Pin
1 and pin 2 closed (a metal plate is connected to Pin 1 and Pin2) for UPS normal operation. To
activate EPO function, remove two screws on EPO port and green connector will be removed.
Note:
The EPO function logic can be set up via LCD setting. Please refer to program 16 in UPS
