13.3.3 Leakage current from the EMC filter built-in type
The EMC filter built-in type includes a grounded capacitor to suppress noise. Since the grounded capacitor
increases leakage current, make sure that no problem occurs in the power supply line and other systems.
Leakage current from the EMC filter built-in type is relatively high, thus establish protective grounding properly.
(Table 13.3-1 shows current values.) The critical value: ≥ 3.5 mA AC or ≥ 10 mA DC (IEC 61800-5-1)
The minimum cross sectional areas of protective grounding wires are shown below:
• 10 mm
2
(copper wire)
• 16 mm
2
(aluminium wire)
Electric shock may occur.

Note 1: The leakage currents for 200 V class
series are calculated based on 240 V/60
Hz (one-phase grounding) and 2%
(interphase voltage unbalance).
Note 2: The leakage currents for 400V class
series are calculated based on 480 V/60
Hz (neutral grounding) and 2%
(interphase voltage unbalance).
