To connect a UPS (Uninterruptible Power Supply), follow these steps:

1. Place the UPS: Choose a suitable location for the UPS, preferably close to the device you want to protect. Ensure there is sufficient space around the UPS for ventilation.

2. Connect the equipment: Connect the equipment you want to protect to the UPS. These can be your computer, modem, router, or other electronic devices. Use the power cables of the equipment and connect them to the appropriate outlets on the back of the UPS.

3. Plug the UPS into the socket: Connect the power cable of the UPS to a suitable wall socket nearby. Ensure the socket is functioning properly and supplies the correct voltage. It is advisable not to use extension cords or power strips between the UPS and the socket, as this can affect the reliability of the power supply.

4. Turn on the UPS: Once everything is correctly connected, you can turn on the UPS. Locate the on/off button on the UPS and switch it on. The UPS will now manage the power supply to the connected equipment.

5. Test the UPS: It is wise to test the UPS to ensure it works properly. Refer to the UPS's manual for specific instructions on performing a self-test. This may involve temporarily cutting off the power supply to the UPS to verify if the connected equipment seamlessly switches to battery power.

Note: Always read the manual of the UPS you are using, as specific instructions and features may vary depending on the brand and model.
