Symbol
Indication
Description
1
Overload
The total load of the equipment connected to the Inverter exceeds the
rating of Inverter.
2
Load level
The higher the load, the more bars illuminate.
3
Inverter is
loaded
When the “Green Mode” is enabled, this symbol is displayed when the
load is over a preset level (adjustable, default is 0% = disabled), and
disappears when the load is under a preset level. Please refer to the
paragraph 4.9.5. When the “Green Mode” is disabled, the symbol is
always displayed.
4
Normal
mode
1) The sine wave symbol will display steadily without battery symbol
when the Inverter is in the normal mode.
Battery
mode
2) The sine wave symbol and battery symbol will blink when the Inverter
is in on-battery (inverter) mode.
Test mode
3) The sine wave symbol will display steadily with blinking battery
symbol when the Inverter is in the test mode.
5
Buck mode
The AVR (Auto Voltage Regulator) is reducing the output voltage of the
Inverter (when the input voltage is too high), and the sine wave symbol,
as mentioned in item 4, is also displayed steadily to indicate that the
Inverter is in the normal mode.
6
Boost mode
The AVR is increasing the output voltage of the Inverter (when the input
voltage is too low), and the sine wave symbol, as mentioned in item 4, is
displayed to indicate that the Inverter is in the normal mode.
7
Timer is
enabled
This symbol will show up in the following situations:
1) A Turn-ON / Turn-OFF schedule has been set using the monitoring
software. Refer to paragraph 5.5 and the “Readme” file or “Help”
function of the monitoring software.
2) The Green Mode is enabled and the load is under a preset level. The
Inverter will turn OFF automatically in 60 seconds. Refer to the
paragraph 4.9.5 of this User’s Manual.
8
HIGH
Thermal
alarm
The temperature inside the transformer is over 90˚C. If the user does
not reduce the load, the temperature will continue to rise and the
inverter will shut down automatically after reaching 95˚C.
9
Fan is at
“High speed”
The symbol will display whenever the cooling fan is running at high
speed, and will disappear when it is off (or running at low speed).
10
Silence mode
The audible alarm has been silenced. To reset the alarm while in on-
battery mode, push the control button (not available when the battery
is low or if Inverter abnormal condition is detected).
11
Inverter fault
The Inverter has failed and must be repaired. Contact a qualified service
person.
12
Battery
normal
1) In normal operation, this symbol indicates a charged battery.
Battery low
2) When the battery charge level is low, the word “LOW” will be added
to the symbol.
13
Battery re-
placement
required
The battery has failed and must be replaced. The battery is checked
each time the Test Function is executed.
14
Battery
charge level
1) The higher the battery voltage, the more bars will illuminate.
2) When the Inverter is charging the battery, the battery symbol and the
level indicator blink together.
LOW
