INSTALLATION AND WIRING
Wiring of main circuit (FR-HC2-H280K)
2.8.2 Wiring of main circuit
(1) Wiring power supply and reactor 1
Use the cable shown in the below table for the connection.
Use the moulded case circuit breaker (MCCB), the earth leakage circuit breaker (ELB) or the magnetic contactor (MC)
shown in the below table.
(2) Wiring reactor 1, filter capacitor, limit resistor, inrush current limit MC, and reactor 2
