Connection Of The Power Regeneration Converter (Mt-Rc) - Mitsubishi Electric A800 Plus Instruction Manual

Connection of stand-alone option units
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.
• The control logic (sink logic/source logic) of the high power factor converter and the inverter must be matched. (Refer to
46.)
• When using a sine wave filter with FR-HC2, select MT-BSL-HC as a reactor for the sine wave filter.
• For the parameter details, refer to the FR-A800 Instruction Manual (Detailed).

Connection of the power regeneration converter
(MT-RC)
When connecting the power regeneration converter (MT-RC), perform wiring securely as shown below. Incorrect connection
will damage the power regeneration converter and the inverter. After making sure that the wiring is correct, set "1 or 101" in
Pr.30 Regenerative function selection.

For wiring to terminals P/+ and N/- of the FR-A842-08660(355K) or lower inverters, up to two cables can be connected. For wiring to the
terminals of the FR-A842-09620(400K) or higher inverters, up to four cables can be connected. To use more cables, use a bus bar.
NOTE
• When using the inverter 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 1 s 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.
• When connecting the power coordination reactor and others, refer to
Instruction Manual of the MT-RC for precautions.
