*1
Input voltage range that can start the UPS by turning the power switch ON.
*2
The value is changed as follows depending on the load capacity.
100V+1.0857x(load capacity%-40%)V to 288 V±3 V (with 40% or more connection load)
100V to 288 V±3 V (with smaller than 40% connection load)
*3
Input voltage range in which normal operation is enabled.
*4
The value is changed as follows depending on the start-up voltage.
(Minimum start-up v10V to 278 V±3 V
*5
When the rated load is connected.
*6
When the UPS is used with the standard AC input plug as a conforming product of UL
standards, use in 4660 VA/4200 W or less.
*7
When the ambient temperature is 25°C.
*8
When the ambient temperature is 25°C and the battery is in its initial state.
*9
At the rated input voltage. To convert into heat value (kJ/h), calculate using the following
formula: Internal power consumption (W) x 3.6.
