Operation for
Planned Power Outages
IMPORTANT
When using a generator temporarily during a planned power outage, use a
generator that meets the following specifications.
Connecting a generator that does not meet the following specifications to the input
section of the UPS may cause the UPS to malfunction or be damaged.
Voltage variation: from 160 to 288Vac
Frequency variation: within rated frequency ± 5% (1Hz/sec.)
Voltage waveform distortion: within 5%
Voltage zero-cross condition: Zero-cross should not occur twice or more
in 1 cycle.
Operation before planned power outage
Turn off the connection device and the UPS before performing the planned
power outage.
1.
Turn off the power to the connected device.
2.
Press the RUN/STOP switch on the front of the UPS for 1
second.
A buzzer will sound when the switch is on.
3.
The output will stop.
The RUN LED (green) on the front of the UPS will flash slowly
(1.6 second cycle).
If the planned power outage is implemented without turning off the UPS, the
UPS will be in the same state as a normal power outage. Until the planned
power outage is completed, power is supplied to the connected equipment
from the UPS's internal battery. After the discharge is completed, power will
not be supplied to the connected equipment until the input power is restored.
Invalid zero-cross
50 Hz or 60 Hz
