Danger
Mandatory
• When using wiring materials and their optional devices for the inverter, they 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.
Be Grounded
• Connect earth cables securely. Failure to do so can lead to risk of electric shock
or fire in case of a failure, short-circuit or leak current.

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 mm
2
or more in diameter.
Note 3:For grounding, use a cable with a size equal to or larger than the above.
Note 4:When using a crimp terminal, cover its caulked part with a tube or use an insulated terminal.
