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.
CAUTION:
For 1 and 2 kVA models, to reduce the risk of fire, connect only to a circuit provided with 20
amperes maximum branch circuit overcurrent protection in accordance with the National Electric Code,
ANSI/NFPA 70.
CAUTION:
For 3 kVA models, to reduce the risk of fire, connect only to a circuit provided with 30 amperes
maximum branch circuit overcurrent protection in accordance with the National Electric Code, ANSI/NFPA
70.
Step 2: UPS output connection
There two kinds of outputs: programmable outlets and general outlets. 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 the
communication cable to the USB/RS-232 port and the other end to the communication port of your PC.
With the monitoring software installed, you can perform these operations:
•
Remote Shutdown of UPS
•
Send shutdown commands to remote computers
•
Remotely set parameters of the UPS
•
Set-up the number of battery strings connected
•
Set-up voltage and frequency ranges
See manual for monitoring software for details.
The UPS is equipped with an intelligent slot perfect for either a SNMP or an AS400 card. Installing either a
SNMP or AS400 card in the UPS will provide advanced communication and monitoring options.
NOTE: 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 the back panel of the UPS unit.
Connect from “OUT” outlet to the equipment with another modem/fax/phone line cable.
