Connection of stand-alone option unit
2.4.3 Connection of the high power factor converter (FR-HC)
When connecting the high power factor converter (FR-HC) to suppress power harmonics, perform wiring securely as shown
below. Incorrect connection will damage the high power factor converter and drive unit.
∗1 Keep input terminals (R/L1, S/L2, T/L3) open. Incorrect connection will damage the drive unit.
∗2 Do not insert an MCCB between the terminals P/+ and N/- (between P and P/+, between N and N/-). Opposite polarity of terminals N/- and P/+ will
damage the drive unit.
∗3 Use Pr. 178 to Pr. 182 (input terminal function selection) to assign the terminals used for the X10, RES signal. (Refer to page 100)
∗4 Be sure to connect terminal RDY of the FR-HC to the X10 signal or MRS signal assigned terminal of the drive unit, and connect terminal SE of the
FR-HC to terminal SD of the drive unit. Without proper connecting, FR-HC will be damaged.
NOTE
The voltage phases of terminals R/L1, S/L2, T/L3 and terminals R4, S4, T4 must be matched.
Use sink logic (factory setting) when the FR-HC is connected. The FR-HC cannot be connected when source logic is
selected.
Do not remove the jumper across terminals P/+ and P1.
