7 ELECTRICAL AND CONTROL SETTINGS
7.1 GENERAL CHECK
• Make sure that the following conditions related to power supply installation are satised:
- The power capacity of the electrical installation is large enough to support the power demand of the YUTAKI system (outdoor
unit + indoor unit + DHW tank (if apply)).
- 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 Z
max
at the interface point of the user’s supply, in accordance with EN61000-3-11.
