2. Installation and Wiring
2-5
Note 1) Inverter Input / Output terminals
The inverter input terminals are L1, L2 and L3. The output terminals to the motor are U, V and W.
Do not connect the power supply to the U, V, W terminals. incorrect wiring will cause to inverter
damage or fires.
Note 2) Wire size
For the main circuit wiring shown in Fig. 2-4, use wires recommended in Table 2-1, including wire
size range, ring terminal and tightening torque. The applicable wire given in Table 2-1 is for using
in constant torque ratings; for variable torque, select the wire given for one higher rating, shifting
one column to the right.
Example:
For the X45K0 drive variable torque, use the column of N30K0 drive (for the N37K0
variable torque, use the N37K0 column however)

Note 3) Circuit Breaker for wiring
Install an MCCB or Fuse and MC on the power supply side of the inverter. Refer to Table 7.2 and
select the MCCB or fuses. UL is meet using right fuse only
Note 4) Rated voltage for auxiliary equipment supply
For the 400 Series(X45K0), wire the link in power supply terminal (TBA) according to the rated
voltage of the power supply being used.
For 380 to 400V, link across 2-3 (factory setting state)
For 415 to 480V, link across 1-2
