3. UPS output connection
   • For output sockets, simply connect devices to the outlets.
   • For output terminals, please follow the steps below for the wiring configuration:
     1. Remove the small cover of the terminal block.
     2. We suggest using AWG 12 ~ 10 or 3.3mm² ~ 5.3mm² power cords for 3kVA. Please install a circuit breaker (40A) between the mains and the AC input of the 3kVA UPS for safe operation.
     3. Upon the completion of the wiring configuration, please check whether the wires are securely affixed.
     4. Install the small cover back to the rear panel.
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 a Mini slot perfect for Delta Mini SNMP IPv6, Mini Relay I/O, or Mini Modbus card (optional). After the Mini card 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 http://datacenter-softwarecenter.deltaww.com
