Step 4: Communication connection
To allow shutdown/ start-up and status monitoring for unattended UPS,
connect one end of the 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
via your PC.
The UPS is equipped with Mini slot perfect for Delta Mini SNMP, Relay I/
O, or MODBUS cards (optional). After the Mini SNMP is installed in the UPS,
advanced communication and monitoring functions will be available.
NOTE :
1. The USB port and the RS-232 port cannot work at the same time.
2. If you choose to use the USB port instead of the RS-232 port, please
install the USB driver software in your computer after connecting
your computer to the UPS's USB port. The software can be
downloaded from

Step 5: Disabling/ enabling of REPO function
NOTE :
Only applicable to models with P/N ending with 0BA.
Keep pin 1 and pin 2 closed for UPS normal operation. To activate REPO func-
tion, cut the wire between pin 1 and pin 2.
The REPO port can be connected to an external switch. After the external
switch is turned to the "OPEN" position, the UPS will switch off the inverter im-
mediately and cut off the UPS output without transferring to the bypass mode.
