Wiring (power regeneration mode)
Wiring between the power supply and the reactor
• Cable gauge differs by the capacity. Select an appropriate cable by referring to
to perform wiring.

For selection of MCCB for the converter, refer to
Wiring between the reactor and the converter
• Cable gauge differs by the capacity. Select an appropriate cable by referring to
to perform wiring.
Wiring between the converter and the inverter
• For the cable gauge of the cable for the main circuit terminals P/+ and N/- (P to P and N to N), refer to
NOTE
• Connecting opposite polarity of terminals P4 and N/- will damage the converter.

Installation of a fuse on each cable is recommended to prevent the damage from
spreading in case of an inverter failure. Select the fuse according to the motor capacity.
To use a motor whose 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
.

Do not install any MCCB between the inverter and the converter (P to P and N to N).
