Indicated below is an example of selecting an earth-leakage current breaker under the following
conditions.

Use an ear
th-leakage current breaker designed for suppressing harmonics/surges.
Find the terms of equation (11.1) from the diagram.
Ig1 = 20 •

Ig2 = 20 •

1000
= 0.1 [mA]
Ign = 0 (not used)
Iga = 0.1 [mA]
Igm = 0.1 [mA]
Insert these values in equation (11.1).
Ig ≥ 10 • {0.1 + 0 + 0.1 + 1 • (0.1 + 0.1)}
≥ 4 [mA]
According to the result of calculation, use an earth-leakage current breaker having the rated sensitivity
current (Ig) of 4.0 mA or more.
An earth-leakage current breaker having Ig of 15 mA is used with the NV-SP/SW/CP/CW/HW series.

POINT
For when multiple servo amplifiers are connected to one EMC filter, refer to
section 6.4 of "EMC Installation Guidelines".
It is rec
ommended that one of the following filters be used to comply with EN EMC directive. Some EMC
filters have large in leakage current.
