Connecting The Power Cord - Epson EL 486UC User Manual

Using the serial ports
If you have a printer, a modem, or a mouse with a serial
interface, you can connect it to one of the serial (Rs232C) ports
on the back of the computer. Make sure you have a cable
compatible with a DB-9P connector.
To connect a serial device, insert the connector into one of the
ports marked COM1 and COM2. If you are connecting only one
serial device, use the COM1 port.

Connecting the Power Cord

Follow these steps to connect the power cord:
1. Plug the power cord into the power inlet on the back panel.
Warning
To avoid an electric shock, be sure to plug the cord into
the computer before plugging it into the wall outlet.
2. Plug the other end of the power cord into an appropriate
grounded electrical outlet.
