7.6.5 To connect the backup heater power supply
The backup heater capacity can vary, depending on the indoor unit
model. Make sure that the power supply is in accordance with the
backup heater capacity, as listed in the table below.
1 Connect the backup heater power supply.
For *3V models, use a single pole fuse for F1B. For *9W models,
use a double pole fuse for F1B.
Special remark for fuses:
CAUTION
If the indoor unit has a tank with a built-in electrical booster
heater (EKHW*), use a dedicated power circuit for the
backup heater and booster heater. NEVER use a power
circuit shared by another appliance. This power circuit must
be protected with the required safety devices according to
the applicable legislation.

(a) Equipment complying with EN/IEC 61000-3-12
(European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public low-
voltage systems with input current >16 A and ≤ 75 A per phase.).
(b) This equipment complies with EN/IEC 61000-3-11
(European/International Technical Standard setting the limits for
voltage changes, voltage fluctuations and flicker in public low-
voltage supply systems for equipment with rated current ≤ 75 A)
provided that the system impedance Z

equipment to ensure, by consultation with the distribution network
operator if necessary, that the equipment is connected only to a
supply with a system impedance Z
