Wiring of main circuit (FR-HC2-H280K)
(6) Wiring the power supply and inverter
Connect the inverter control power supply directly to the power supply without connecting a converter in between.
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.
