APC Back ES-550VA UPS - Setting it Up
(Page 3 of 5 )
The registration papers can be found inside the package, along with a letter listing the address and the taxes in your location/country. Happily, online registration is also permitted, so you can just log on the PAC official site and finish this quickly. The benefits of doing so are that you’ll be able to download firmware/software packages from the site.
In the box near the CD (picture on the previous page) is also packed the User’s Guide in several languages. Reading it, you’ll find out that the UPS came with one wire disconnected, and you need to plug it. Okay, flip the device over, slide the back down, and you’ll discover the battery. It sits quite solidly in there and looks like this:

This can turn out to be tougher than it sounds, but it's nothing that can’t be resolved with a screwdriver. Slide the battery back, close the compartment, and plug the USB cable into the computer while the other end goes into the UPS; then plug in the power cord and you’re ready to go. Push the power button and the device will signal with a beep if it is correctly set up. Now all you need to do is to enjoy the Schuko output connections: four with battery back-up and surge protection, and four with only surge protection.
Additionally, there is a place to plug in the printer/router, also with some Ethernet cable. A circuit breaker button is also implemented, just to make the device complete. The device can also work without a computer connection, but in that case it won’t shut down the computer in case of a blackout. As for each problem you might have, troubleshooting by using a combination of the Power/Replace Battery indicator and sound signals is described clearly the User guide.
The UPS can be also mounted on the wall vertically or horizontally. All in all, it looks good and it’s very practical -- a definite thumbs-up for a job well done by APC! The power cord is somewhat short in my opinion (6 feet), but this is compensated for by the many excellent Schuko output connections in it.
