2.3.3 Recommended wire sizes
Table 2.6 lists the recommended wire sizes. The recommended wire sizes for the main circuit terminals for an ambient temperature of 50
C are indicated for two types of wire: HIV single wire (for the
maximum allowable temperature 75°C) (before a sla sh (/)) and IV single wire (for 6 0°C) (after a slash
(/))

DCR: DC reactor
*1 Use crimp termina ls covered with an insulated shea th or insulating tube. Recom mended wire sizes are
for HIV
/IV (PVC in the EU).
*2 Wire sizes are calcul ated on the basis of inp ut RMS current under the c ondition that the po wer suppl
y
capacity and impedance are 500 kVA and 5%, respectively.
*3 Insert the DC reactor (DCR) in either of the primary power input lines. Refer to C hapter 10 for more
details.
2.3.5 Wiring for main circuit terminals and grounding terminals
Inverter output terminals, U, V, W and grounding terminal ( G)
1) Connect the three wires of the three-phase motor to terminals U, V, and W, aligning phases each other.
2) Connect the grounding wire of terminals U, V, and W to the grounding terminal (
G).
3) If the cable from the inverter to the motor is very long, a high-frequency current may be generated by stray
capacitance between the cables and resul t in an over current trip o f the inverter, an increase in leakage
current, or a reduction in current indication precision.
When a motor is driven b y a PWM-type inverter, the motor terminals may be subject to surge voltage gen erated by inverter element switching. If the motor cable (with 460 V series motors, in particular) is particularly
long, surge voltage will deteriorate motor insulation. To prevent this, use the following guidelines:
Inverters of 7.5 HP or above
Motor Insulation Level 1000 V 1300 V 1600 V
460 VAC Input Voltage 66 ft (20 m) 328 ft (100 m) 1312 ft (400 m)*
230 VAC Input Voltage 1312 ft (400 m)* 1312 ft (400 m)* 1312 ft (400 m)*
Inverters of 5 HP or below
Motor Insulation Level 1000 V 1300 V 1600 V
460 VAC Input Voltage 66 ft (20 m) 165 ft (50 m) 165 ft (50 m)*
230 VAC Input Voltage 328 ft (400 m)* 328 ft (100 m)* 328 ft (100 m)*
* For this case the cable length is determined by secondary effects and not voltage spiking.
When a motor protective thermal O/L relay is inserted between the inverter and the motor, the
thermal O/L relay may malfunction (particularly in the 460 V series), even when the cabl e
length is 165 ft (50 m) or less. T o correc t, insert a fil ter or red uce the carri er frequenc y. (Use
function code F26 (Motor sound).)
