Note 1: In wide range, if the input frequency suddenly changes from 50 Hz to 60 Hz, for example,
the UPS switches to battery mode to maintain the output frequency at 50 Hz. If the input
continues at the frequency of 60 Hz for 100 cycles or more, the UPS provisionally
increases the frequency of the output from the battery from 50 Hz to 60 Hz, and once the
output wave form and input wave form are synchronized, the output mode is switched to
line output. On the other hand, in normal range, if the input frequency suddenly changes,
the UPS switches to battery mode and the battery output continues with an output
frequency of 50 Hz.
Note 2: Eco mode is a mode in which during normal operation, the input voltage is output as it is
in order to directly output the commercial power. (The commercial power is directly output
so power consumption is low).
Because during normal operation the commercial power is directly output, the output
frequency is the same as the input frequency.
* During Eco mode operation, when the “AC input” voltage is within ±10% of the set output
voltage, the commercial power is directly output.
* This mode is not compatible with 100 V output mode.
Note 3: Only 1 item can be set.
Note 4: The reboot mode has the following 2 modes.
Mode A: After the UPS has stopped, when the AC input is detected as ON, the UPS is immediately
started up.
Mode B:
After the UPS has stopped, when the AC input is detected as “OFF”→”ON”, the UPS is
automatically started up.
(Definition of AC input OFF: When the AC input is OFF for 1 second or more).
* These modes are enabled when automatic restart is enabled in the boot settings.
* This setting mode is enabled only after the UPS has been stopped by the backup stop
signal (BS) of the contact signal.
* When the shutdown software is used with the RS-232C connector connected to the cable,
mode A operates regardless of the settings.
(1) When the UPS is stopped by BS signal after occurrence of a power outage
