Danger

When using the inverter without the front cover, be sure to place the inverter unit inside a

Mandatory

cabinet. If they are used outside the cabinet, it may cause electric shock.

Be sure to ground every unit. If not, it may cause electric shock or fire on the occasion of

Be grounded

failure, short-circuit or electric leak.

(*1): Indicates

wire sizes

of input terminals R, S, T and output terminals U, V, W. Wiring distance is supposed to

be 30 m at maximum.

(*2): The recommended cable size is that of the cable (e.g. 600V class,HIV cable) with continuous maximum permissible temperature of 75°C.

(*3): For the control circuit, use shielded wires whose size (cross-section) is 0.75 mm2 or more. The size (cross- section) of wires supplying control power is 2.0 mm2 or more.

(*4): For the earth cable, use wires larger than the specified ones in size (cross-section). (UL standard)

(*5): Recommended wire size for external braking resistor. Refer to 6.13.4 for use of external braking resistor.

(*6): Do not connect more than two wires to a terminal block (except for terminal blocks of 2900, 4160K to 4280K and PA terminals of models that have only one PA terminal). If wiring with more than two wires is needed, set a external relay terminal.
