Mitsubishi Electric A800-GF Instruction Manual page 66

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
41.)
• 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).
2.10.3
Connection of the power regeneration converter
(MT-RC)
When connecting the power regeneration converter (MT-RC), perform wiring securely as follows. Incorrect connection will
damage the power regeneration converter and the inverter. After making sure that the wiring is correct and secure, set "1 or
101" in Pr.30 Regenerative function selection.

supply

For the FR-A842-08660(355K) or lower, up to two cables can be connected to terminals P/+ and N/-. For the FR-A842-09620(400K) or higher,
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 one second 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 be shut off or damaged.
• When connecting the power coordination reactor and others, refer to Instruction Manual of the MT-RC for precautions.
