a fuse other than in the table.
(b) Installation of Ground Fault Interrupter
When connecting a ground fault interrupter to input terminals L1, L2 and L3, select one
that is not affected by high frequency.
(c) Installation of Magnetic Contactor
When the main circuit power supply is shut OFF in the sequence, a magnetic contactor (MC)
can be used instead of a molded−case circuit breaker (MCCB). However, when a magnetic
contactor is switched OFF at the primary side, regenerative braking does not function and
the motor coasts to a stop.
S The load can be operated/stopped by opening/closing the magnetic contactor at the
primary side. However, frequent switching may cause the inverter to malfunction.
S When using a braking resistor unit, use a sequencer to break power supply side on
overload relay trip contact. If the inverter malfunctions, the braking resistor unit may
be burned out.
(d) Terminal Block Connection Sequence
Input power supply phases can be connected to any terminal regardless of the order of L1,
L2 and L3 on the terminal block.
(e) Installation of Line Filter
Install an input line filter to reduce EMC noise. For specifications of the line filter, refer
to Par. 3.4.
