INSTALLATION AND WIRING
Wiring of main circuit (FR-HC2-7.5K to 75K, FR-HC2-H7.5K to H220K)
(6) Wiring reactor 1 and converter
Supply power to the power detecting terminals (R/L1, S/L2, T/L3) separately from the main circuit wiring.
(7) Wiring of the power supply and inverter
For the inverters equipped with the control circuit power supply terminals (R1/L11 and S1/L21), connect the control circuit
power supply terminals (R1/L11 and S1/L21) directly to the power supply. Do not connect through the converter.
<Wiring example of 7.5K>
The terminal arrangement differs by capacity. Check the terminal arrangement on 2.6.2
Terminal arrangement of the main circuit terminal (refer to page 28) and 6.3 Outline dimensions
(refer to page 150).
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, S, T of the converter to the power supply, the converter
will be damaged.
NOTE
Refer to the Instruction Manual of the inverter, and remove the jumpers across terminals R/L1and R1/L11 and across
terminals S/L2 and S1/L21 on the inverter main circuit.
For the inverters equipped with the control circuit power supply terminals (R1/L11 and S1/L21), always connect the
power supply to the terminals. Inverter control power is provided. If not connected, the inverter may trip or be
damaged.
Power supply and the inverter are not connected for the inverters not equipped with control circuit power supply
terminals (R1/L11 and S1/L21).
