Specifications

Back-UPS Pro 500 BG500 120 Vac 35
• No-Load Shutdown: The UPS will shutdown to conserve energy if while operating on battery power the
UPS detects that connected equipment is using less than 15W of energy for more than 5 minutes.
• Electrical noise is unwanted electromagnetic energy which lowers the quality of signals and data. When
there is too much noise, your UPS intervenes by supplying battery power. You can specify the response to
noise through Sensitivity. Use the High, Medium, and Low options in the Sensitivity drop-down box when
there is a lot of noise.
Daylight Saving Time
Path: UPS > Advanced Settings > Daylight Saving Time
Enable traditional United States
Daylight Saving Time (DST), or enable
and configure a customized daylight
saving time to match how Daylight
Saving Time is implemented in your
local area. DST is disabled by default.
When customizing Daylight Saving
Time (DST):
• If the local DST always starts or
ends on the fourth occurrence of
a specific weekday of a month
(e.g, the fourth Sunday), choose
Fourth/Last. If a fifth Sunday
occurs in that month in a
subsequent year, the time setting still changes on the fourth Sunday.
• If the local DST always starts or ends on the last occurrence of a specific weekday of a month, whether it is
the fourth or the fifth occurrence, choose Fifth/Last.
Firmware Update
To use this option the firmware update file must have been previously sent using FTP and stored in the
/upsfw/ directory.
This update refers to the firmware on the UPS. Don’t confuse this with a UPS card firmware upgrade!
