6.1 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 2014/30/EU, relating to electromagnetic compatibility, the table
below indicates the Maximum permitted system impedance Z
user's supply, in accordance with EN 61000‑3‑11.

NOTE
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 EN 61000‑3‑2 and EN
61000‑3‑12, is as follows:
Equipment complying with EN 61000‑3‑2 (Professional use)
Equipment complying with EN 61000‑3‑12
• Check to ensure that existing installation (mains power switches, circuit breakers, wires,
connectors and wire terminals) already complies with the national and local regulations.
• The use of the DHW tank heater is disabled as factory setting. If it is desired to enable the DHW
tank heater operation during normal unit operation, adjust the DSW4 pin 3 of the PCB1 to the
ON position and use the adequate protections.
