6.1 General check
• Make sure that the following condions related to power supply installaon are sased:
✓ The power capacity of the electrical installaon 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 Direcve 2004/108/EC, relang to electromagnec compability, the
table below indicates the Maximum permied system impedance Z
max
at the interface point of
the user’s supply, in accordance with EN61000‑3‑11.
