NOTE: Multiple phases are shown in multiple columns. For example, a unit with 3-phase input will display 3 columns of
status data.
Input Status Options
L-N voltage (V)
Line-neutral voltage of input power.
L-N current (A)
Line-neutral current of input power.
Frequency (Hz)
Frequency of input of input power.
L-L voltage(V)
Line-line voltage of input power.
Power Factor
Power factor of the input power.
Energy (kWh)
Input power.
Input black count
The number times that the input voltage was lost or dropped below 60 VAC (black out). Resets to 0 when UPS is
powered down.
Input brown count
The number of times that the input voltage was too low to support the load and the UPS was forced to switch to
battery power (brown out). Resets to 0 when the UPS is powered down.
Bypass Status Options
L-N voltage (V)
Line-neutral voltage of bypass power.
Frequency (Hz)
Frequency of bypass power.
L-L voltage(V)
Line-line voltage of bypass power.
Battery Status Options
Battery status
Current battery state: charging, discharging, or fully charged.
Battery voltage (V)
Voltage of battery power.
