2-1 Settable items and explanations
There are 5 items to select.
1) Cold start ON/OFF setting
2) Input power sensitivity setting
3) Output voltage setting
4) Power output stop delay time setting *
5) Signal input/output test *
* Can be used when the SC07 (option) is added.
The settings available for this operation are shown below.
1) Cold start ON/OFF setting
• Cold start OFF mode
The unit can start up only when there is AC input.
• Cold start ON mode
It is possible to start up the unit even when there is no AC input plug.
(It is not possible, however, to start up the unit by the remote signals.)
Normal operation occurs when AC input is ON. The output frequency is the same as the fre-
quency the last time there was AC input.
• When using the cold start function
When performing operation with cold start a second time, turn OFF the power switch and wait
at least 20 seconds before turning it back ON.
If the time is too short, UPS may not start up.
2) Input power sensitivity setting
Three types of input sensitivity can be set.
• Standard voltage sensitivity mode (100V AC mode and 115V AC mode)
The power failure detection voltage is set to the standard setting.
• Low voltage sensitivity mode (100V AC mode and 115V AC mode)
The power failure detection voltage is 5V lower than the standard setting.
• High voltage sensitivity (100V AC mode)
The power failure detection voltage is 5V higher than the standard setting.
● The allowable voltage ranges for each setting are shown below.
