● With some types of devices, the effect of inrush current may cause this unit to stop operating properly.

● An inductive device is one that has transformers, coils, motors, etc. built into the input.

Do not fail to confirm the system operation beforehand if the unit is used combined with devices which power supply frequency fluctuate widely, such as private electric generator.

● This unit automatically recognizes the input power frequency when input power is supplied.

● If the unit is connected when the input power frequency is not stable at the rated level, the unit may misidentify

the power supply frequency and may fail to operate normally. (If the unit is in operation, changing from commercial power supply to another power supply source, such as generating equipment, will cause no problem.)

Do not install or store the unit in a place exposed to direct sunlight.

● The rise of temperature may cause the built-in battery to deteriorate rapidly and become unusable.

Do not perform a withstand voltage test.

● The input circuit has a built-in surge absorption device. A withstand voltage test may break it.

● When performing an insulation resistance test, use the 250 VDC range.

Before stopping commercial power to the unit, turn OFF the power switch of the unit.

● The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery Mode, the battery life may be significantly shortened.

Do not fail to confirm the system operation beforehand if the unit is used other than "Output 100V mode".
