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.
Use the cable shown in the below table for the connection of each phase between the reactor 1 and reactor 2.
3) Connecting limit resistor thermostats to the converter
Connect a limit resistor thermostat across the converter terminals ROH and SD.
