Operating Procedures
32
After “Green DOUBLE CONVERSION”
lights, it might go off depending on the
input power condition or the load device
condition.
You can operate the UPS even when the state of the AC input power supply is not
good.
You can follow the procedure below to operate the UPS when the AC input power supply is in an
abnormal state (power outage, voltage drop, etc.).
Since power is supplied to the load devices from the battery in the UPS when this procedure is used,
use the devices for a period of time less than the possible backup time of the UPS.
①
Check that
MAIN MCCB
is set to “OFF”.
②
Press
and hold until the buzzer sounds. Release it when the buzzer sounds.
* The default setting of the output frequency at UPS startup by this
procedure is shown in the right table. Change the setting
according to the using load devices if needed. See §3.4 “Setting
Battery Power Startup Frequency” in the
User Settings Guide
for
details. However, the setting cannot be changed if
MAIN MCCB
is not set to “ON”, so preset this setting when there is a normal AC
input power supply during UPS operation.
At this step, turn the load device power on.
“Green LOAD LEVEL 25 - 100%” will light depending on the connected load capacities.
If the “Red O.L” lights and the buzzer sound is emitted (four short beeps followed by another four
short beeps), the load devices connected to the UPS exceed the rated capacity of the UPS. Reduce the
number of load devices connected.
