Operational Indicators
There are eight LED indicators on the inverter’s top chassis which display the unit’s operating
condition. The table below details their meaning:
LEDs Meaning
LOW
VOLTAGE
Blinks red when the input voltage nears the minimum limit for operation.
Glows red when the input voltage is too low for operation. The Bypass LED will
also glow red and the Invert LED will turn off.
The shutdown and start-up thresholds for the low voltage alarm can be
adjusted using InverterWizard. See InverterWizard for more information.
HIGH
VOLTAGE
Blinks red when the input voltage nears the maximum threshold for operation.
Glows red when the input voltage is too high for operation. The Bypass LED
will also glow red and the Invert LED will turn off.
OVER TEMP Blinks red when the unit’s internal temperature nears the safe limit. The
inverter will automatically derate its maximum power rating to try to
maintain a safe operating temperature.
Glows red when the inverter is too hot to operate. The Bypass LED will
also glow red and the Invert LED will turn off.
OVER LOAD Blinks red when the current being drawn reaches the unit’s continuous rating.
Glows red when the current being drawn reaches the unit’s peak rating.
50 HZ Glows green if the inverter’s output frequency is set to 50.00 Hz. This
setting can be changed using InverterWizard.
If the alarm sounds and both the 50 Hz and 60 Hz LEDs glow red. The unit
is experiencing a ground fault and the Ground Fault Interruptor has shut
down the unit.
60 HZ Glows green if the inverter’s output frequency is set to 60.00 Hz. This set-
ting can be changed using InverterWizard.
If the alarm sounds and both the 50 Hz and 60 Hz LEDs glow red. The unit
is experiencing a ground fault and the Ground Fault Interruptor has shut
down the unit.
BYPASS Glows green if the inverter is in Bypass mode and functioning as an Off-line
Uninterruptible Power Supply. For more information, see Off-line UPS.
Glows red when the inverter is experiencing a malfunction.
INVERT Glows green when the inverter operating normally.
