When using figure 6 or figure 7, only the switches in the phases other than the phase for the
7 F6 h! R" w0 c2 H- \motor are disconnected, if the construction of the appliance permits so. Otherwise all 3

currents are measured separately and the values for the motor and the relevant phase for the& r; F1 R. ~& n0 S+ C4 V- u
heating element are added.
