Danger
•When using switchgear for the inverter, it must be installed in a cabinet.
Failure to do so can lead to risk of electric shock and can result in death or serious injury.
Danger
Mandatory
•Connect earth cables securely. Failure to do so can lead to risk of electric shock or fire in case of a failure,

Note 1: Sizes of the wires connected to the input terminals R, S and T and the output terminals U, V and W when the length of each wire does not exceed 30m.
Note 2: For the control circuit, use shielded wires 0.75 mm2 or more in diameter.
Note 3: For grounding, use a cable with a size equal to or larger than the above.
