Warning
Mandatory
action
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.
Be Grounded
Connect grounding cables securely.
Failure to do so can lead to risk of electric shock or fire in case of a failure or short-circuit or electric
leak.

Note 1: Sizes of the wires connected to the input terminals R/L1, S/L2 and T/L3 and the output terminals U/T1,
V/T2 and W/T3 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: The cable sizes specified in the above table apply to HIV cables (copper cables shielded with an insulator
with a maximum allowable temperature of 75°C) used at an ambient temperature of 50°C or less.
