LCD Back-light Saving: When no UPS button is pressed or no power event occurs during this delay, the LCD
screen will be turned off.
Wiring Fault Detecting: If this option is enabled, the UPS will detect if the UPS wiring is not grounded or reversed.
It is recommended to assure the UPS wiring has ground connection first. This option should be enabled if the UPS
wiring has ground connection.
Dry Relay Function: This configures the power condition for the UPS dry relay to function when the selected
condition occurs. Refer to UPS manual for further information about advanced UPS dry relay utilization. The Dry
Relay Function provides the following power conditions:
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.
