Connection of stand-alone option units
2.4.6 Connection of the power regeneration converter (MT-RC)
(01800 or more)
When connecting a power regeneration converter (MT-RC), perform wiring securely as shown below. Incorrect
connection will damage the regeneration converter and inverter. After connecting securely, set "1" in
Pr. 30 Regenerative function selection and "0" in Pr. 70 Special regenerative brake duty.
2.4.7 Connection of the power factor improving DC reactor (FR-HEL)
(1) Keep the surrounding air temperature within the permissible range (-10C to +50C). Keep enough clearance
around the reactor because it heats up. (Take 10cm or more clearance on top and bottom and 5cm or more on left
and right regardless of the installation direction.)
(2) When using the DC reactor (FR-HEL), connect it between terminals P1 and P/+.
For the 01160 or less, the jumper connected across terminals P1 and P/+ must be removed. Otherwise, the
reactor will not exhibit its performance. For the 01800 or more, a DC reactor is supplied. Always install the reactor.
CAUTION
 When using the FR-F700 series together with the MT-RC, install a magnetic contactor
(MC) at the input side of the inverter so that power is supplied to the inverter after 1s
or more has elapsed after powering ON the MT-RC. When power is supplied to the
inverter prior to the MT-RC, the inverter and the MT-RC may be damaged or the
MCCB may trip or be damaged.
 Refer to the MT-RC manual for precautions for connecting the power coordination
reactor and others.
Parameters referred to
Pr. 30 Regenerative function selection, Pr. 70 Special regenerative brake duty Refer to page 108
CAUTION
 The wiring distance should be within 5m.

The size of the cables used should be equal to or larger than that of the power supply cables (R/L1, S/L2, T/L3). (Refer to page 17)
