E. Bypass LED: This LED will light when the maintenance bypass breaker is
closed. When the maintenance bypass breaker is closed, the inverter cannot
be switched on and will stop immediately even when inverter is already
running.
F. Reserve LED: This LED will light when the reserve breaker is closed, and
there is AC power supply present at the reserve terminal.
G. Rectifier LED: This LED will light when the rectifier is operating normally,
meaning the rectifier Mains are within the range specified, the rotation
sequence of three phases is correct, the rectifier breaker is closed, and no
high DC voltage is on the bus.
H. Back-up LED: This LED will light when the ELI is in back-up mode. This
is also as the indicator for battery test result. If the battery test does not pass,
this LED will flash even if the ELI is not in back-up mode, to prompt the
user to change the batteries.
I. Inverter LED: This LED will light when the inverter is switched on,
indicating whether the inverter is running or not.
J. Inverter SS LED: This LED will light when the inverter static switch is
turned on and the reserve static switch is turned off, i.e., the load is supplied
from the inverter. Usually this LED will light 7 seconds after the inverter is
switched on.
K. Reserve SS LED: This LED will light when the reserve static switch is
turned on and the inverter static switch is turned off, i.e., the load is supplied
from the reserve. Since the reserve static switch and inverter static switch
will never both turn on simultaneously, the Inverter SS LED and the Reserve
SS LED should never both be lit simultaneously.
L. Output LED: This LED will light when there is AC power present at the
output terminal. This is an important indication to the user at to whether AC
is available at the output or not.
