• If the MCCB is to be used in common among multiple Inverters, or other devices, set up a sequence such that the power supply will be turned off by an fault output, as shown in the following diagram. 200-V class: 3-phase, 200 to 230 VAC, 50/60 Hz 400-V class: 3-phase, 380 to 460 VAC, 50/60 Hz Power supply Note: For 400-V class, connect a 400/200-V transformer. (See note) Inverter L1 (R) L2 (S) L3 (T) Fault output (NC) Installing a Ground Fault Interrupter Inverter outputs use high-speed switching, so high-frequency leakage current is generated. In general, a leakage current of approximately 100 mA will occur for each Inverter (when the power cable is 1 m), and approximately 5 mA for each additional meter of power cable. Therefore, at the power supply input area, use a special-purpose breaker for Inverters, which detects only the leakage current in the frequency range that is hazardous to humans and excludes high-frequency leakage current. • For the special-purpose breaker for Inverters, choose a ground fault interrupter with a sensitivity amperage of at least10 mA per Inverter. • When using a general leakage breaker, choose a ground fault interrupter with a sensitivity amperage of 200 mA or more per Inverter and with an operating time of 0.1 s or more. Installing a Magnetic Contactor If the power supply for the main circuit is to be shut off because of the sequence, a magnetic contactor can be used instead of a molded-case circuit breaker. When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop a load, however, the regenerative braking does not work and the load coasts to a stop. • A load can be started and stopped by opening and closing the magnetic contactor on the primary side. Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down. • When the Inverter is operated with the Digital Operator, automatic operation cannot be performed after recovery from a power interruption. • If the Braking Resistor Unit is to be used, program the sequence so that the magnetic contactor is turned off by the contact of the Unit’s thermal relay. Connecting Input Power Supply to the Terminal Block Input power supply can be connected to any terminal on the terminal block because the phase sequence of input power supply is irrelevant to the phase sequence (L1, L2, and L3). Installing an AC Reactor If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advance capacitor is switched, an excessive
peak current may flow through the input power circuit, causing the converter unit to break down. To prevent this, install an optional AC reactor on the input side of the Inverter. This also improves the power factor on the power supply side. Installing a Surge Absorber Always use a surge absorber or diode for the inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes. Wiring the Power Terminal of the Inverter with 18.5- to 160-kW Output Refer to the following to wire terminals L1 (R), L2 (S), L3 (T), L11 (R1), L21 (S1), and L31 (T1). • Three-phase Power Input Make sure that terminals L1 (R) and L11 (R1), L2 (S) and L21 (S1), and L3 (T) and L31 (T1) are short-circuited before supplying power to the Inverter. These terminals are short-circuited with short bars before shipping. The Inverter may break down if only terminals L1 (R), L2 (S), and L3 (T) or terminals L11 (R1), L21 (S1), and L31 (T1) are supplied with power. • 12-pulse Rectification Terminals L1 (R) and L11 (R1), L2 (S) and L21 (S1), and L3 (T) and L31 (T1) are short-circuited with short bars before shipping. Be sure to remove the short bars when using 12-pulse rectification, otherwise the Inverter will break down. Installing a Noise Filter on Power Supply Side Install a noise filter to eliminate noise transmitted between the power line and the Inverter.
