・The recommended cable size is that of the cable (e.g. 600V class, HIV cable) with continuous
maximum permissible temperature of 75°C.
・For the control circuit, use shielded wires whose size is 0.75mm
operation power supply, use the electric wires whose size is 2.0mm
・When using a Harmonic Suppression Unit SB3 as a DC power supply, the optional initial
charger may not be required or the inverter may need to be remodeled. Please contact your
Toshiba distributor if you like detailed information.
