ON/
OFF
Output stopped due to the
detection of a short-circuit
on connected device side
or due to connections sig-
nificantly exceeding capac-
ity limit. Check that the DC input of
connected devices is not
short-circuited, or that the
connection capacity does not
exceed the rated capacity.

Blink 4
(*1)
(*2) OFF --- ON Output cannot be started
because the DC input volt-
age is outside the specified
range.
Note:
If this display occurs
when the unit has been
stopped by input of the
backup stop signal (BS)
(Page 7-2) or by using
the UPS monitoring soft-
ware (Page 6-2), the rem-
edy to the right is not
required because the
input voltage is within the
specification range.
Use in the DC input voltage
range described in the speci-
fication.
