This product can cause a d.c. 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 transformator.
