Power regeneration mode
∗1
Connect between the inverter terminal P/+ and the converter terminal P4 and between the inverter terminal N/- and the converter terminal
N/- for polarity consistency.
Connecting the opposite polarity of terminals P/+ and N/- will damage the converter and the inverter.
∗2
Confirm the correct phase sequence of three-phase current to connect between the reactor and the converter, and between the power supply
and the reactor.
Incorrect connection will damage the converter.
∗3
Always connect between the power supply and terminals R/L1, S/L2, and T/L3 of the converter. Operating the inverter without connecting them will
damage the converter. A branch point to each of these terminals must be placed between the power supply and the FR-HAL reactor.
∗4
Install the FR-HAL reactor between the node points joined to the converter terminals R/L1, S/L2, and T/L3 and the node points joined to the FR-
XCL reactor. For information to select an appropriate model, refer to
∗5
To connect a DC reactor, remove a jumper installed across terminals P1 and P/+ before installing the DC reactor.
∗6
To use separate power supply for the control circuit, remove each jumper at terminal R1/L11 and terminal S1/L21.
∗7
For selection of an MCCB for the converter, refer to
.
∗8
Install the UL listed fuse (refer to
) on the input side of the FR-XCL reactor to meet the UL/cUL standards.
∗9
Do not install an MCCB or MC between the reactors and the converter. Doing so disrupts proper operation.
