 Utility Failure: The utility power fails and the UPS is using the battery power.

 Low Battery: The battery capacity is low and cannot support the connected computers if they require a

shutdown.

 Alarm: The UPS is issuing an audible alarm due to a warning event, such as Overload

 Bypass: The UPS has switched to bypass mode due to an overload or UPS fault.

 UPS Fault: The UPS may be malfunctioning due to an internal problem, such as an inverter fault, bus fault or

overheating.

 Redundant Quantity: Sets the quantity of UPS modules to be power redundancy. This power redundancy can

provide the fault-tolerant protection against failures of equivalent UPS modules. UPS should avoid exceeding

output load from whom deducted the power redundancy; otherwise UPS cannot afford the equivalent fault-tolerant

protection as user’s desire.

NCL Outlet

NCL stands for Non-Critical Load. Under the following conditions, the UPS will turn off the NCL outlet to conserve

battery power and maximize battery runtime for the remaining outlets:

 Turn Off Threshold: When supplying battery power, the UPS will power off this NCL outlet if the remaining

battery capacity is lower than this threshold.

 Turn Off Delay: When supplying battery power, the UPS will power off this NCL outlet after this delay time is met.

 Turn On Delay: When the utility power is restored, the UPS will restore the output of this NCL outlet after the

delay time is met. This prevents excessive power consumption caused by all the connected equipment starting at

the same time.

Note: Not all models provide the same configurations. These configurations will vary by model.

Diagnostics

The UPS/Diagnostics page provides the ability to verify that the UPS can supply adequate battery runtime for the

connected computers to shutdown properly. Perform a complete runtime calibration to ensure an accurate estimate of

the runtime for the connected load. The buzzer can be tested to ensure that the UPS can issue an alarm and that the

indicator lights will display properly if requested by the UPS.
