In accordance with the requirement of the IEC standard, the maximum permissible system impedance (Zmax) at the interface
point of the power supply to be connected with this icemaker must be 0.23+j0.23 ohm. Determine in consultation with the
supply authority, if necessary, that the icemaker is connected only to a supply of 0.23+j0.23 ohm or less.
