High-function General-purpose Inverter RX2 Series User’s Manual
In general, a leakage current of approximately 100 mA will flow for the power cable length of 1 m per
inverter. Moreover, an additional leakage current of approximately 5 mA will flow with the increasing
length by 1 m.
Therefore, earth leakage breaker that will be used at the power supply input shall be the followings:
• It must remove a leakage current with high frequency.
• It must detect only leakage current in a frequency band that is hazardous to human beings.
• It shall be for an inverter.
• Use an earth leakage breaker that is dedicated for an inverter. Pay an attention that the breaker
with a sensitive current of 10 mA or more shall be selected per an inverter.
• When the general earth leakage breaker (to detect a high frequency leakage current) is used, it
must be selected with the sensitive current 200 mA or more and the operation time of 0.1 sec. or
more per an inverter. However, since even a low frequency sensitive current has a high value, the
effect to prevent an electric shock may reduce. Select it at a location that a human being unlikely
touch to protect other devices.
Leakage current of EMC noise filter
EMC noise filter is designed in conformity with CE standard in Europe.
When the noise filter designed according to neutral ground based on Europe power supply specifi-
cation is used with S-phase ground in-house, a leakage current increase.
• With the condition of the noise filter installation in which a leakage current is strictly regulated on
the use in-house, when the installation site is not applicable to EMC regulation, disable built-in
EMC noise filter and consider use of 3G3AX-ZCL and a ferrite core as a measure against a noise.
• EMC noise filter for 3G3RX2 is enabled at factory default setting. If unnecessary, change from
enable to disable. As for the changing method, refer to
2-3-2 Arrangement and Function of Main
• Confirm the following: while the use of the noise filter (3G3AX-NFI) at input side of an external
option leads to a noise reduction, it does to a generation of a leakage current.
External Filter
Refer to the following table.
It is efficient to improve the status on whether it conforms to EMC or not.
When setting the light duty mode, select a maximum applicable motor capacity of the light duty
mode.
