2.7 Wiring of main circuit

(FR-HC2-7.5K to 75K, FR-HC2-H7.5K to H220K)

 Perform wiring securely to conform with the harmonic suppression guideline of the former Ministry of International

Trade and Industry (currently the Japanese Ministry of Economy, Trade and Industry). Incorrect wiring causes the converter to display an alarm or causes an fault or damage.

 Refer to the Instruction Manual of each inverter for the wiring of the inverter. Special attention must be paid to the wiring length and wire gauge.

Connection diagram (when using with the FR-A700 series)

Connection method differs by the inverter series. Perform connection by referring to the Instruction Manual of the inverter.

 Do not connect anything to the inverter power input terminals R/L1, S/L2 and T/L3. Incorrect connection will damage the inverter. Connecting opposite polarity of terminals P and N will damage the converter and the inverter.

 Use input terminal function selection to assign the terminal used for X10 signal. (Refer to the Instruction Manual of the inverter.)

 The power phases of the terminals R4/L14, S4/L24, and T4/L34 and the terminals R/L1, S/L2, and T/L3 must be matched.

 Do not insert MCCB between terminals P and N (P and P, N and N).

 Always connect the terminal R/L1, S/L2, T/L3 of the converter to the power supply. If the inverter is operated without connecting the terminals to the power supply, the converter will be damaged.



Do not insert MCCB or MC between (1) (terminal R/L1, S/L2, and T/L3 input of the Reactor 1) and (4) (terminal R4/L14, S4/L24, and T4/L34 input of the

converter) of the above diagram. It will not operate properly.

 Securely perform grounding (earthing) by using the grounding (earthing) terminal.

 Installation of a fuse is recommended.

(Refer to page 11)

 The MC power supply stepdown transformer is only equipped in the 400V class models.
