Smart-UPS C 1000/1500/2000/3000 VA 120/230 Vac Rack-Mount 2U6
Sensitivity adjustment settings
The UPS detects and reacts to line voltage distortions by transferring to battery backup power to protect
connected equipment. In situations where the connected equipment is too sensitive for the input voltage
level it is necessary to adjust the transfer voltage.
1. Connect the UPS to a AC power source. Be sure the UPS is turned off.
2. Place the unit in Configuration Mode, as described in page 9.
3. Use the Sensitivity Setting option to set the transfer voltage range.
When the UPS is in Configuration Mode, the Sensitivity bar graph icons display the sensitivity level
setting. Refer to the examples here as a reference.
