Output Charge displayed Description
on top
The load of the
connected devices
exceeds the rated
capacity. If the
operation of UPS is
ON ON
continued, it is
or or Fault-E9
switched to bypass
OFF OFF
operation in the case
of normal operation,
and output stops in
the case of backup
operation.
There is a fault
due to overload,
OFF Fault-EO
so output has
stopped.
Output has
stopped due to a
short circuit on the
connected device
ON Fault-ES
side or a major
connection
capacity overload.
The output voltage is
high, and thus if the
operation of UPS is
ON
continued, it is
ON
or switched to bypass
or Fault-E1
operation in the case
Disch
OFF
of normal operation,
arging
and output stops in
the case of backup
operation.
The output voltage is
low, so if continued in
ON
ON
normal operation, it
or
or Fault-E2 will change to bypass
Disch
operation, and if in
OFF
arging
backup operation
output will stop.
The battery charging
voltage is high, and
thus if the operation of
ON
UPS is continued, it is
ON
or
switched to bypass
or Fault-E3
operation in the case
Disch
OFF
of normal operation,
arging
and output stops in
the case of backup
operation.
The battery charging
voltage is low, so if
ON
continued in normal
ON
or operation, it will
or Fault-E4
change to bypass
Disch
OFF
operation, and if in
arging
backup operation
output will stop.
○: ON, ●: OFF
Solution
Turn off the power
switches of all the
devices connected to
the UPS, and after
reducing the
connected devices,
turn on the "Power"
switches of the UPS
and the connected
devices.
Note: The load
amount can be
checked from
the LCD Menu
by "1.
Measurements"-
"Load Meter"
Check whether a short
circuit is occurring on the
AC input of the
connected device, or the
connected capacity is
exceeding the rated
capacity.
Turn off the power
switches of all the
devices connected to
the UPS, and turn on
the power switch of
the UPS only. If the
displayed content
does not change, the
UPS is faulty. Contact
the shop of purchase.
Note: The output
voltage can be
checked from
the LCD Menu
by "1.
Measurements"-
"Input/Output
Meter". The
battery voltage
can be checked
by "1.
Measurements"
- "Battery
Meter".
