Wiring of main circuit (FR-HC2-H280K)

1) Filter capacitor

Install three filter capacitors in parallel to the output side of the reactor 1 or to the input side of the inrush current limit

MC as shown in the above diagram.

Use the cable shown in the table below for the connection of filter capacitor.

2) Limit resistor, inrush current limit MC

Install a pair of a limit resistor and a inrush current limit MC to the output side of the reactor 1, and install another pair of those to the input side of the reactor 2.

Install the limit resistor to the appended terminal block. Short a terminal block with a terminal block shorting conductor, and use them as a pair in each phase. Connect the appended terminal blocks to the appended inrush current limit MCs.

 Installation of a fuse is recommended to avoid the damage to spread in case of an inverter failure. Select a fuse according to the motor capacity. When using a motor, of which the capacity is smaller than the inverter capacity by two ranks or more, select the fuse capacity according to the inverter capacity.

Refer to the fuse selection table on page 11

.

When connecting several inverters, the wire gauge of terminal P/+ and N/should be same as the wire gauge of the inverter's power supply side. (Refer to the Instruction Manual of the inverter.)

 The function of the inverter terminal, which is connected to the terminal RDY of the converter, needs to be set at the inverter side.

 Refer to the Instruction Manual of the inverter.

Do not insert MCCB between terminals P/+ and N/- (P and P, N and N).

NOTE

 The converter operates as a common converter. Use terminals P/+ and N/- to connect it with the inverter. Do not connect anything to the inverter power input terminals R/L1, S/L2, and T/L3. Incorrect connection to the inverter power input will damage the inverter. Connecting opposite polarity of terminals P/+ and N/- will damage the inverter and the converter.

 Do not connect the DC reactor to the inverter when using a high power factor converter.

(5) Wiring reactor 1 and converter

Supply power to the power detecting terminals (R/L1, S/L2, T/L3) separately from the main circuit wiring.

Switch the tap (V1, V2, V3) of the MC power supply stepdown transformer according to the input power supply voltage as shown in the below table.

NOTE

 The terminal R/L1, S/L2, and T/L3 of the converter are control terminals to detect power supply phases of the power supply. The voltage phases of the terminals R4/L14, S4/L24 and T4/L34 and the terminals R/L1, S/L2 and T/L3 must be matched. If these terminals are not connected correctly, the converter does not operate properly.

 If the inverter is operated without connecting the terminals R/L1, S/L2 and T/L3 of the converter to the power supply, the converter will be damaged.
