2.10.6 Connection of the multifunction regeneration converter (FR-XC) Common bus regeneration mode with harmonic suppression disabled (Pr.416 = "0") 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 (connection mode setting switch) in the function selection switch assembly (SW2). If the switch setting does not match the actual wiring, the connection mode fault "E.T" occurs. After making sure that the wiring is correct and secure, set "2 or 102" in Pr.30 Regenerative function selection .

Doing so will damage the inverter and the converter.
*2 Instead of connecting the terminals to the AC power supply, the control circuit can be powered by connecting terminal R1/L11 to terminal P/+ and terminal S1/L21 to terminal N/-. In this case, do not connect the terminals to the AC power supply. Doing so will damage the inverter. *3 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. Refer to page 56 for the jumper connection status in the initial setting.) 106 2. INSTALLATION AND WIRING 2.10 Connection of stand-alone option units Fuse*9 Fuse*9 *8 Fuse
