Connection Of The Multifunction Regeneration Converter (Fr-Xc) (Standard Model / Ethernet Model) - Mitsubishi Electric 800 Series Instruction Manual

*6 Do not install an MCCB or MC across terminals (R/L1, S/L2, T/L3) on the reactor 1 and terminals (R4/L14, S4/L24, T4/L34) on the FR-HC2. Doing
so disrupts proper operation.
*7 Securely perform grounding (earthing) by using the grounding (earthing) terminal.
*8 Installation of a fuse is recommended. (Refer to the Instruction Manual of the FR-HC2.)
NOTE
• The safety communication model (FR-E800-SCE) is not intended for the use with the high power factor converter (FR-HC2).
• 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.
• The control logic (sink logic/source logic) of the high power factor converter and the inverter must be matched. (Refer to
60.)
• Do not connect a DC reactor (FR-HEL) to the inverter when the FR-HC2 is connected.
CAUTION
• Always connect terminal RDY on the FR-HC2 to a terminal where the X10 signal or MRS signal is assigned on the
inverter. Always connect terminal SE on the FR-HC2 to terminal SD on the inverter. Not connecting these terminals may
damage the FR-HC2.
2.9.4 Connection of the multifunction regeneration
converter (FR-XC) (Standard model / Ethernet
model)
When connecting the multifunction regeneration converter (FR-XC) to improve the braking capability, perform wiring securely
as follows. Failure to do so will damage the converter and the inverter.
Turn ON switch 1 in the function selection switch assembly (SW2). If the switch setting does not match the actual wiring, the
connection mode fault "E.T" occurs. Set "0" in Pr.416 of the FR-XC converter.
After making sure that the wiring is correct and secure,
set "0" or "2" (when the automatic restart after instantaneous power failure is selected) in Pr.30 Regenerative function
selection, and set "0" in Pr.70 Special regenerative brake duty. (Refer to the FR-E800 Instruction Manual (Function).)
 Common bus regeneration mode with harmonic suppression disabled
(Pr.416 = "0")

Power
supply
*1 Never connect the power supply to terminals R/L1, S/L2, and T/L3 on the inverter. Doing so will damage the inverter and the converter.
*2 When the FR-XC is connected, the jumper across terminals P/+ and P1 does not affect the function. (The FR-XC can be connected with the
jumper connected.)
*3 Connect between the inverter terminal P/+ and the converter terminal P/+ and between the inverter terminal N/- and the converter terminal N/-
for polarity consistency. Failure to do so will damage the converter and the inverter.
*4 Confirm the correct phase sequence of three-phase current to connect between the reactor and the converter, and between the power supply
and terminals R/L1, S/L2, and T/L3. Failure to do so will damage the converter.
