Caution (for installation and connection)
For AC input terminal block models, connect the grounded phase of the
AC input power supply to the G terminal ( ) of the unit.
If either of the others are grounded apart from the grounded phase,
connect the grounded phase to the L2 terminal of the unit.
⚫ If connected differently, it may cause a breakdown of the connected device.
Do not connect devices with rated voltage other than
200/208/220/230/240/100 VAC.
⚫ The rated output voltage of the unit is 200/208/220/230/240/100 VAC.
⚫ There is a possibility of a breakdown of the connected device due to excess
voltage.
Do not connect devices that cannot be used with the commercial power
supply.
⚫ When the unit is set to “Eco mode” and a fault occurs on the device, operation is
switched to direct commercial power, and the commercial power supply is provided
to the connected device as it is.
Do not connect 4 or more expansion battery units to this unit.
⚫ Up to 3 expansion battery units can be connected to the unit.
⚫ There is a risk of smoke generation and ignition if 4 or more are connected.
Do not place objects onto this unit, or drop heavy objects onto it.
⚫ There is a risk of not only a unit breakdown, but also personal injury in cases such
as the unit tipples over.
If the input plug is pulled out while the unit is operating, do not touch the
metal parts of the input plug under any circumstances.
⚫ There is a risk of an electric shock.
⚫ The leakage current of the unit on its own is equal to or less than the safety rating
(leakage current: 3.5 mA), but the leakage current may increase depending on the
connected devices, so do not touch the metal parts of the input plug.
⚫ When the unit is operating, a voltage is generated on the metal parts of the input
plug through the capacitor of the internal circuit, regardless of the elapsed time.
