Mandatory
• When using the inverter without the front cover, be sure to place the inverter unit inside a cabinet. If
they are used outside the cabinet, it may cause electric shock.
Be Grounded
• Be sure to ground every unit. If not, it may cause electric shock or fire on the occasion of failure,
short-circuit or electric leak.

(*1): Indicates wire sizes of input terminals R, S, T and output terminals U,V,W.
(*2): The recommended cable size is that of the cable (e.g. 600V class,HIV cable) with continuous maximum permissible
temperature of 75°C. Ambient temperature is 50°C or less and the wiring distance is 30m or less.
(*3): For the control circuit, use shielded wires whose size (cross-section) is 0.75 mm
2
or more.
(*4): For the earth cable, use wires larger than the specified ones in size (cross-section).
(*5): Recommended wire size for an optional braking resistor. Refer to 5.19 for use of external braking resistor.
(*6): Recommended wire size for internal DC reactor.
