2-2. Setup the UPS

Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
 For 208/220/230/240VAC models: The power cord is supplied in the UPS package.
 For 110/115/120/127VAC models: The power cord is attached to the UPS. The input plug is a
NEMA 5-15P for 1000 and 1000L models, NEMA 5-20P for 2000 and 2000L models.
Note: For Low voltage models: Check if the site wiring fault indicator lights up in LCD panel. It will
be illuminated when the UPS is plugged into an improperly wired utility power outlet (Refer to
Troubleshooting section).
Step 2: UPS output connection

For socket-type outputs, 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.

For terminal-type input or outputs, please follow below steps for the wiring configuration:
a) Remove the small cover of the terminal block
b) Suggest using AWG14 or 2.1mm

Step 3: Communication connection
Communication port:
USB port
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.
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.
