*1: Main circuit power supply

3ph-240V class: three-phase 200-240V-50/60Hz

1ph-240V class: single-phase 200-240V-50/60Hz

1ph-120V class: single-phase 100-120V-50/60Hz

*2: The inverter is supplied with the PO and the PA/+ terminals shorted by means of a shorting bar.

Before installing the DC reactor (DCL), remove the bar.

*3: When using the OUT output terminal in sink logic mode, short the NO and CC terminals.

When using the NO output terminal in source logic mode,short the P24 and OUT terminals.

*4: 1ph-240V models have noise filter inside.

*5: 1ph-120V models cannot be used with DC reactors.

*6: When external potentiometer is connected by using P5 terminal, set the parameter f109=3

*7: When using VI terminal as a logic input terminal, set the

parameter f109=2 and connect as following

schematics. Be sure to connect a resistor between

P24 and VI terminals in case of sink logic, between

VI and CC terminals in case of source logic.

(Recommended resistance: 4.7k -1/2W)

The T/L3 terminal is not provided for

single-phase models.

Use the R/L1 and S/L2/N terminals as input terminals.

Note 1. Be sure to attach a surge killer to the exciting coil of the relay and the magnetic contactor.



Note 2. When using the auxiliary contacts 2a of the magnetic contactor MC for the control circuit, connect the contacts 2a in parallel to increase reliability.

Note 3. When a motor is driven by commercial power supply using commercial power supply / inverter switching circuit, use a magnetic contactor appropriated AC-3 class the motor rated current.



Note 4. Select an MCCB with a rataed interrupting current appropriate to the capacity of the power supply, because short-circuit currents vary greatly depending on the capacity of the power supply

and the condition of the wiring system. The MCCB, MC and ELCB in this table were selected, on the assumption that a power supply with a normal capacity would be used.



Note 5. 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.

The numeric values in parentheses refer to the sizes of wires to be used when a DC reactor is connected.



Note 6. For the control circuit, use shielded wires 0.75 mm2 or more in diameter.

Note 7. For grounding, use a cable with a size equal to or larger than the above.



Note 8. 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.

(Explanation in case of sink logic)

Multifunction programmable analog input.

Factory default setting: 0-10Vdc(10 bits resolution) and 0-60Hz (0-50Hz) frequency input.

The function can be changed to 4-20mAdc (0-20mA) current input by parameter =

setting and 0-5Vdc (10 bits

resolution) voltage input by parameter =

setting.

By changing parameter =

setting, this terminal can also be used as a multifunction programmable logic

input terminal. Be sure to insert a resistor between P24-VI (4.7 k



-1/2 W) in case of sink logic, between VI-CC in

case of source logic.
