Do not connect anything to the inverter power input terminals R/L1, S/L2, and T/L3. Incorrect connection will damage the inverter. Connecting opposite
polarity of terminals P and N will damage the converter and the inverter.
Use input terminal function selection to assign the terminal used for X10 signal. (Refer to the Inverter Instruction Manual.)
The power phases of the terminals R4/L14, S4/L24, and T4/L34 and the terminals R/L1, S/L2, and T/L3 must be matched.
Do not insert MCCB between terminals P/+ and N/- (P and P, N and N).
Always connect the terminal R, S, and T of the converter to the power supply. If the inverter is operated without connecting the terminals to the power supply,
the converter will be damaged.
Do not insert MCCB or MC between (1) (terminal R/L1, S/L2, T/L3 input of the converter) and (2) (terminal R4/L14, S4/L24, T4/L34 input of the converter) of
the above diagram. It will not operate properly (except for the inrush current limit MC).
Securely perform grounding (earthing) by using the grounding (earthing) terminal.
Installation of a fuse is recommended. (Refer to page 28)
The number of filter capacitors and filter capacitor alarm detectors differs by the capacity. Connect two sets of filter capacitors and filter capacitor alarm
detectors for H400K, and connect three sets for H560K.
NOTE
• When connecting the converter to the inverter, match the control logic (sink logic (initial setting)/source logic). The
converter does not operate properly if the control logic is different.
(Refer to the Instruction Manual for the switching of the control logic. Refer to the Inverter Instruction Manual for the
switching of the control logic of the inverter.)
• Keep the wiring length between terminals as short as possible.
• When sudden large distortion or depression of power supply occurs, reactor may generate abnormal acoustic noise.
This acoustic noise is caused by the power supply fault and not by the damage of the converter.
• Do not connect the DC reactor to the inverter when using a high power factor converter.
• When using a sine wave filter with FR-HC2 (75K or higher), select MT-BSL-HC as a reactor for the sine wave filter.
