detects a valid input voltage but ON button has
not been pressed.
B- Flow chart indicates AC input is used to
recharge batteries only.
ONLINE
A
–
In online mode, Input voltage indicates a
valid AC input close to (232VAC).
B
–
Output voltage is displayed in upper left
corner (B)
C
–
Flowchart indicates AC input is used to
recharge batteries but also feeds rectifier input.
Inverter output is generated by inverter.
BATTERY MODE
A- Input indicator at bottom left corner (A)
shows Battery voltage since there is no valid AC
input detected.
B- Output indicator displays AC output
generated by internal inverter.
C- AC input symbol must be turned off
representing there is no valid AC input detected
by Inverter.
D- Clock symbol lights and backup time is
displayed on the screen.
BYPASS MODE
A- Input and output indicators must show a
similar value since output has been feed by
input through static internal bypass line.
B- Flowchart shows static bypass line is active.
Converters icon is turned off representing
inverter is OFF.
ECO MODE
A- ECO symbol is active on LCD
B- Flowchart indicates output is powered from
input.
FREQUENCY CONVERTER
