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.
