Connection of stand-alone option unit
2.4.3
Connection of the high power factor converter (FR-HC2)
When connecting the high power factor converter (FR-HC2) to suppress power harmonics, perform wiring securely as shown
below. Incorrect connection will damage the FR-HC2 and the inverter.
After making sure that the FR-HC2 is properly connected, set the following parameters.
Pr. 19 Base frequency voltage
Pr. 30 Regenerative function selection (Refer to page 131)
MC
MCCB
AC power
supply
Do not connect anything to the input terminals (R/L1, S/L2, T/L3). Incorrect connection will damage the inverter.
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 inverter.
Use Pr. 178 to Pr. 182 (input terminal function selection) to assign the terminals used for the X10 and RES signals. (Refer to page 134)
Be sure to connect terminal RDY of the FR-HC2 to the X10 signal or MRS signal assigned terminal of the inverter, and connect terminal SE of the
FR-HC2 to terminal SD of the inverter. Without proper connecting, FR-HC2 will be damaged.
Always connect the R/L1, S/L2, and T/L3 terminals of FR-HC2 to the power supply. Operating the inverter without connecting them will
damage FR-HC2.
Do not install an MCCB or MC between the reactor 1 terminals (R/L1, S/L2, T/L3) and FR-HC2 terminals (R4/L14, S4/L24, T4/L34). It will
not operate properly.
Securely perform grounding (earthing) by using the ground (earth) terminal.
Installation of a fuse is recommended. (Refer to the Instruction Manual of FR-HC2.)
NOTE
The voltage phases of terminals R/L1, S/L2, and T/L3 and terminals R4/L14, S4/L24, and T4/L34 must be matched.
Match the control logic (sink logic/source logic) of the FR-HC2 and the inverter. (Refer to page 27 )
Do not connect a DC reactor (FR-HEL) to the inverter when FR-HC2 is connected.
Filterpack connection is not available when FR-HC2 is connected.
