*1: Make sure that both the VA value and the W value of the load capacity connected to the UPS are within the
range specifi ed here.
*2: Check the operation beforehand if the unit is used in any mode other than “100V AC mode”. In some cases,
the maximum voltage of output in Battery Mode may be lower than the maximum voltage in usual operation
(commercial power supply).
*3: The backup times shown here are for when rated load is connected, at 20
°
C, and for initial characteristics.
*4: When an additional battery unit is connected, the charging time is 24 hours.
*5: The height includes the 13-mm height of the rubber feet.
