Electric wiring and the application
General check
• Make sure that the following conditions related to power supply installation are satisfied:The power capacity of
the electrical installation is large enough to support the power demand of the HAIER system.
The power supply voltage is within ±10% of the rated voltage.
The impedance of the power supply line is low enough to avoid any voltage drop of more than 15% of the rated
voltage.
• Following the Council Directive 2004/108/EC, relating to electromagnetic compatibility, the table below indicates
the Maximum permitted system impedance Zmax at the interface point of the user's supply, in accordance with
