10. Peripheral devices
• 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.
Mandatory
• Connect earth 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, 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
Note 3: For grounding, use a cable with a size equal to or larger than the above.
Note 4: The wire sizes specified in the above table apply to HIV wires (cupper wires shielded with an insulator
with a maximum allowable temperature of 75°C) used at an ambient temperature of 50°C or less.
