Wiring of main circuit (FR-HC2-7.5K to 75K, FR-HC2-H7.5K to H220K)
(5) Wiring of high power factor converter and inverter
• These units should be connected to transmit commands from the high power factor converter to the inverter securely.
Connection method differs depending on the inverter series. Refer to the Instruction Manual of the inverter when
connecting.
Refer to the below table for the wiring length.
For the wire gauge of the main circuit terminals P/+ and N/- (across P and P, across N and N), refer to 2.6.3 Cable sizes of the
main control circuit terminals and earth (ground) terminals (refer to page 31).
<Wiring example of 7.5K>
The terminal arrangement in the main circuit differs by capacity. Check the terminal arrangement on 2.6.2 Terminal arrangement of the main circuit terminal
(refer to page 28).

Other control signal lines 30m or less
NOTE
The converter operates as a common converter. Use terminals P/+ and N/- to connect it with the inverter. Do not
connect anything to the inverter power input terminals R/L1, S/L2, and T/L3. Incorrect connection to the inverter
power input will damage the inverter. Connecting opposite polarity of terminals P/+ and N/- will damage the inverter
and the converter.
Do not connect the DC reactor to the inverter when using a high power factor converter.

Installation of a fuse is recommended to avoid the damage to spread in case of an
inverter failure. Select a fuse according to the motor capacity. When using a motor, of
which the capacity is smaller than the inverter capacity by two ranks or more, select the
fuse with the capacity that is one rank lower than the inverter capacity. Refer to the fuse
selection table on page 11, 13.
When connecting several inverters, the wire gauge of terminal P/+ and N/- should be
same as the wire gauge of the inverter's power supply side. (Refer to the Instruction
Manual of the inverter.)
The function of the inverter terminal, which is connected to the terminal RDY of the
converter, needs to be set at the inverter side.
Refer to the Instruction Manual of the inverter.
Do not insert MCCB between terminals P/+ and N/- (P and P, N and N).
