For wiring to terminals P/+ and N/- of the FR-F842-08660(400K) or lower inverters, up to two cables can be connected. For wiring to the
terminals of the FR-F842-09620(450K) 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.
