5.2.2.2.1 When the casing of the appliance is entirely of metal, no metal foil is needed, but the terminal M of the RC element shall be connected directly to the body of the appliance.
5.2.2.2.2 When the casing of the appliance is of insulating material, metal foil shall be wrapped round the handles, e.g. in Figure 8b, around handle B, and also round the second handle D, if present. Also metal foil 60 mm wide shall be wrapped round the body C at that
point where the iron core of the motor stator is located, or around the gearbox if this gives a higher disturbance level. All these pieces of metal foil, and the ring or bushing A, if present, shall be connected together and to the terminal M of the RC element.
5.2.2.2.3 When the casing of the appliance is partly metal and partly insulating material, and has insulating handles, metal foil shall be wrapped round the handles, as handles B and D in Figure 8b. If the case is non-metallic at the location of the motor, a metal foil 60 mm wide shall be wrapped round the body C at that point where the iron core of the motor stator is located, or alternatively around the gearbox, if this is of insulating material and a higher disturbance level is obtained. The metal part of the body, the point A, the metal foil round the handles B and D and the metal foil on the body C shall be connected together and to the terminal M of the RC element.
5.2.2.2.4 When a class II appliance has two handles of insulating material A and B and a case of metal C, for example an electric saw (Figure 8c), metal foil shall be wrapped round the handles A and B. The metal foil at A and B and the metal body C shall be connected
together and to the terminal M of the RC element.
