8.1 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 YUTAKI system (outdoor 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 at the interface point of the user's supply, in
max
accordance with EN61000-3-11.

NOTE
(*)Only for RASM-(4-7)(V)R1E: The data corresponding to DHW tank
heater is calculated in combination with the domestic hot water
tank accessory "DHWT-(200/300)S-3.0H2E".
• The status of Harmonics for each model, regarding
compliance with IEC 61000-3-2 and IEC 61000-3-12,
is as follows:
