User Manual Back-UPS BC500-RS, BC650-RS6

For Mac operating systems, we recommend using the native shutdown

application (within System Preferences) which recognizes your battery backup

and allows you to configure shutdown of your system during power outages.

To access this application, connect a USB cable from the Back-UPS DATA

PORT (POWERCHUTE PORT) to a USB port on your computer, and see the

documentation provided with your computer.

Installation

Connect the Back-UPS to a computer using a USB cable. Plug one end into the

PowerChute Port on the rear panel of the Back-UPS and the other into a USB

port on your computer.

Insert the PowerChute CD into your computer and follow the on-screen

instructions.

If your Back-UPS did not come with a PowerChute CD, a free download is

available on the APC Web site. On the computer, go to www.apc.com/tools/

download. Select “Software Upgrades - PowerChute Personal Edition” in the

“Filter by Software/Firmware” drop down menu. Select the appropriate

operating system. Follow directions to download the software.

Transfer Voltage and Sensitivity Settings

Voltage regulation

The Back-UPS will switch to battery power if the AC input voltage level

becomes too low or too high, or if the AC power is experiencing voltage

fluctuations.

No-load shutdown

The UPS will shut down to conserve energy if while operating on battery

power the UPS detects that connected equipment is using less than 15 W of

energy for more than 15 minutes.

Disable this feature if low power consuming equipment like ADSL-modem or

wi-fi router is connected to the Back-UPS.

No-load shutdown can be enabled or disabled through Program mode

described below.

Voltage sensitivity adjustment

If the Back-UPS switches to battery power too frequently or too infrequently,

adjust the transfer voltage and sensitivity settings:

1 2 3 4 5 6 7 8 9 10 11 12 13 14
