sides of the UPS for heat dissipation and easy-maintenance.
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
⚫
For 100/110/115/120/127VAC models: The power cord is attached to the UPS. The input plug
is a NEMA 5-15P for 1K and 1.5K models, NEMA 5-20P for 2K model and NEMA L5-30P for 3K
model.
Note:
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).
Please also check if there is a circuit breaker against overcurrent and short circuit between the
mains and AC input of the UPS for safety operation. The recommended protection value as
following:
⚫
For 100/110/115/120/127VAC models: 15A for the 1K and 1.5K models, 20A for 2K model and
30A for 3K model.
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 port:
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.
Step 4: Network connection
Network/Fax/Phone surge port
Connect a single modem/phone/fax line into surge-
protected “IN” outlet on the 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 7 in UPS
setting for the details.
