Low Voltage: This LED blinks red when the input
voltage nears the minimum limit for proper operation. It
glows red when the input voltage is too low for proper
operation. The Bypass LED will also glow red and the
Invert LED and AC Power LED will turn off.
High Voltage: The LED blinks red when the input
voltage nears the maximum limit for proper operation. It
glows red when the input voltage is too high for proper
operation. The Bypass LED will also glow red and the
Invert LED and AC Power LED will turn off.
Over Temp: This LED blinks red if the unit’s internal
temperature nears the safe limit. The Inverter will
automatically derate its maximum power rating to maintain a safe operating temperature. This
LED glows red if the Inverter is too hot to operate. The Bypass LED will also glow red and the
Invert LED and AC Power LED will turn off.
Over Load: This LED blinks red if the current drawn by the load reaches the unit’s continuous
rating. It glows red if the current drawn reaches the peak rating.
50 Hz: This LED glows green if the Inverter is set to output frequency of 50.00 Hz. This setting
can be changed using InverterWizard.
60 Hz: This LED glows green if the Inverter is set to output frequency of 60.00 Hz. This setting
can be changed using InverterWizard.
Bypass: This LED glows green if the Inverter is in Bypass mode. This feature is only available
on units with the Off-Line UPS option. For more information, see Off-line UPS section. This LED
glows red if the Inverter is experiencing an alarm condition.
Invert: This LED glows green when the Inverter operating normally.
Operation
Controls and Indicators
Before operating, the Inverter must be properly installed and the load(s) and batteries must be
properly connected. See Installation, DC Connections, and AC connections for more information.
Move the power switch to ON to energize the circuitry. The AC Power LED, Invert LED, and either
the 50 Hz or 60 Hz LED will glow green indicating the presence of AC power at the output. The
inverter will begin supplying the load with voltage and current printed on its label.
The Inverter’s front panel features 8 LED indicators to display the unit’s operating condition.
Their functions are detailed below.
