NOTE
Leakage Current
The earth leakage current from the frequency converter
exceeds 3.5 mA. To ensure that the earth cable has a good
mechanical connection to the earth connection, the cable
3 3
2
cross section must be at least 10 mm or 2 rated earth
wires terminated separately.
Residual Current Device
This product can cause a DC current in the protective
conductor. Where a residual current device (RCD) is used
for protection in case of direct or indirect contact, only an
RCD of Type B is allowed on the supply side of this
product. Otherwise, another protective measure shall be
applied, such as separation from the environment by
double or reinforced insulation, or isolation from the
supply system by a transformer. See also Application Note
Protection against Electrical Hazards MN90G202.
Protective earthing of the frequency converter and the use
of RCDs must always follow national and local regulations.
