Installing a Magnetic Contactor (MC)
•If the power supply of the main circuit is shut off due to sequencing, a magnetic contactor (MC) can
be used. (When forcibly stopping the load with an MC on the primary side of the main circuit,
however, the regenerative braking does not work and the load coasts to a stop (free run).)
•Frequently opening and closing the magnetic contactor (MC) to start and stop a load may cause
damage to the Inverter. To extend the life of the Inverter's internal electrolytic capacitor, limit the
frequency to no more than once every 30 minutes.
Connection Sequence to the Terminal Block
•Input power supply can be connected to any terminal because the phase sequence of the input
power supply is irrelevant to that of the terminal block (R/L1, S/L2, and T/L3).
Installing an AC Reactor
•If the Inverter is connected to a large-capacity power transformer (660 kVA or more) or the phase
advance capacitor is in use, a large peak current may flow through the input power circuit, causing
damage to the converter unit.
•Install an optional AC reactor on the input side of the Inverter. An AC reactor will also improve the
power factor of the power input side.
Installing a Surge Absorber
•Always use a surge absorber or diode when magnetic contactors (MC), electromagnetic relays,
solenoid valves, solenoid, and magnetic brakes are used.
Installing a EMC Filter on the Input Side
•The Inverter's output uses high-speed switching, so noise may be transmitted from the Inverter to
the power line, affecting peripheral devices.
•It is recommended that a noise filter be installed on the input side to minimize noise transmission.
(Installing a noise filter on the input side can also reduce the noise from the power line to the
Inverter.)
Recommended Input Filters for the Inverter
* Use the recommended noise filter for each inverter. A general-purpose noise filter will be less ef-
fective and may not reduce noise.
