Wiring of main circuit (FR-HC2-H400K, H560K)
(6) Wiring the power supply and inverter
Connect the inverter control power supply directly to the power supply without connecting a converter in between.

Cable gauge
0.75 to 2mm
NOTE
Refer to the Instruction Manual of the inverter, and remove the jumpers across terminals R/L1 and R1/L11 and across
terminals S/L2 and S1/L21 in the inverter main circuit.
Always connect the power supply to the inverter. It supplies power to the inverter's control power and large-capacity
cooling fan. If not connected, the inverter may come to a trip or be damaged.
(7) Wiring filter capacitor alarm detector and converter
Use the cable shown in the below table for the connection.
Cable gauge
Before wiring, read the Instruction Manual appended to the filter capacitor alarm detector carefully.

Connect the wiring to the terminals R5/L15 and S5/L25 of the MC power supply stepdown transformer by placing parallel with the wiring of (5) Wiring reactor
1 and converter (Refer to page 51).
Install the mini relay using the provided mini relay terminal block (PYF14T) and the mini relay clip (PYC-A1).
