System Configuration and Setup
Once the UTS has been installed and connected to utility power by a qualified electrician, the UTS is ready for
configuration and setup.
System setup
Press the System Setup button located on the front of the UTS to enter system setup mode and to navigate through the
system setup options.
Use the down/up arrow buttons to navigate through the configuration options and to change values displayed on the LCD.
Note: The settings and values selected will change immediately after an arrow button is pressed.
The LCD will revert back to the starting display message after 30 seconds with no activity.
Bypass Mode
Use the up arrow key to select NO, indicating that bypass mode is disabled or YES,
enabling bypass mode on the UTS.
In bypass mode, all circuits are powered by the utility power source. Backup power
sources are not used to power loads regardless of the status or quality of the primary
utility power source.
Warning: Changing bypass mode settings while connected to utility power will cause all connected
loads to be momentarily disconnected.
When bypass mode is enabled, overload protection is provided. High and low voltage protection is not
available when bypass mode is enabled.
Load Shedding
Use the down/up arrow keys to select ON, indicating that load shedding is enabled or
OFF, to disable load shedding.
The UTS provides intelligent load management, defined by APC as adaptive load
management (ALM).
When a backup power source is nearing an overload condition, ALM intelligence sheds (drops) select loads and then
reconnects the loads when adequate power becomes available. ALM selects the most suitable loads to drop and reconnect
at any given time minimizing overall load disruption, and maximizing backup power capability.
When load shedding is enabled (ALM is on), the average energy output of a backup power source can increase by 20% or
more. This allows more loads to be connected without overloading or stalling a backup power source.
When load shedding is disabled (ALM is off), overload conditions can occur causing a generator to stall, a circuit breaker
to trip, or loads may experience severe low voltage conditions.
Load Shedding must be enabled for each circuit to be set individually for specific maximum time off and minimum time
on. Refer to Circuit Maximum Time Off and Minimum Time On section in this manual.
Voltage Sensitivity
Use the down/up arrow keys to select High, Medium, or Low voltage sensitivity.
The voltage sensitivity level determines how the UTS reacts to voltage fluctuations.
Medium voltage sensitivity setting is a suitable setting for most situations.
High voltage sensitivity setting is recommended only for loads that are very sensitive to voltage fluctuations.
Low voltage sensitivity setting is recommended for loads that can tolerate most power fluctuations.
