Precaution on selection and operation
SAFETY INSTRUCTIONS
To use the product safely and correctly, make sure to read the Instruction Manual before using the product.
This product has not been designed or manufactured for use with any equipment or system operated under life-threatening
conditions.
Please contact our sales office when you are considering using this product in special applications such as passenger
mobile, medical, aerospace, nuclear, power or undersea relay equipment or system.
Although this product was manufactured under conditions of strict quality control, you are strongly advised to install safety
devices to prevent serious accidents when it is used in facilities where breakdowns of the product or other failures are likely
to cause a serious accident.
Do not use this product for a load other than dedicated inverters.
Wiring distance
For the wiring distance between the high power factor converter (FR-HC2) and inverter, refer to the following table.
Across terminals P and P / terminals N and N
Other control signal lines
The total wiring distance between the high power factor converter (FR-HC2) and standard accessories must be 30m or
shorter. (For 280K or higher, refer to the Instruction Manual.)
Reactor installation at power supply side
The terminals R/L1, S/L2, and T/L3 of the high power factor converter are control terminals to detect power phases of the
power supply. When wiring, the voltage phases of terminals R4/L14, S4/L24, and T4/L34 and the voltage phases of
terminals R/L1, S/L2, and T/L3 must be matched. Failure to connect these terminals correctly will lead to an improper
operation of the high power factor converter.
If the inverter is operated without connecting the terminals R/L1, S/L2, and T/L3 of the high power factor converter to the
power supply, the high power factor converter will be damaged.
The Guideline treats the converter as a no-harmonic-emitting device (K5 = 0), but the harmonic component is not
completely 0.
Connectable inverter
Connect to the inverter that can accept DC inputs.
For the MELTRAC, FR-A500L, and FR-F500L series inverters, make sure the connecting inverter is compatible with the
high power factor converter. Connection with an incompatible inverter will damage the inverter and the converter.
Sine wave filter selection precautions
When using a sine wave filter with FR-HC2 (75K or higher), use MT-BSL-HC for the sine wave filter.
