Connection Of The High Power Factor Converter (Fr-Hc2) - Mitsubishi Electric FR-E700EX Instruction Manual

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 high power factor converter and the drive unit.
Perform the wiring securely, and set the following parameter:
Pr.30 Regenerative function selection = "0" (Initial value).
MCCB
Three-phase
AC power
supply

Do not connect anything to power input terminals (R/L1, S/L2, T/L3). Incorrect connection will damage the drive unit.

Do not install an MCCB for the terminals P/+ and N/- (between terminals P and P/+ or between N and N/-). Connecting the opposite polarity of terminals
N/- and P/+ will damage the drive unit.

Assign the X10, RES signal to a terminal using any of Pr.178 to Pr.189 (input terminal function selection). (Refer to page 138)

Always connect the FR-HC2 terminal RDY to a terminal where the X10 or MRS signal is assigned in the drive unit. Always connect the FR-HC2 terminal
SE to the drive unit terminal SD. Not connecting these terminals may damage the FR-HC2.

Always connect the R/L1, S/L2, and T/L3 terminals of FR-HC2 to the power supply. Operating the drive unit 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 the voltage phases of 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 drive unit. (Refer to page 21)
 Do not connect a DC reactor (FR-HEL) to the drive unit when FR-HC2 is connected.
 A Filterpack cannot be connected when FR-HC2 is connected.
