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.

(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
is less than or equal to Z
sys
between the user's supply and the public system. It is the
responsibility of the installer or user of the 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
less than or equal to Z

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.

(a) For configuration of the backup heater, see "8.2.2 Quick wizard:
Standard" on page 35.
Special remark for fuses:
Special remark for terminals:
As mentioned on the table above, the connections on the terminals
X6M and X7M need to be changed to configure a backup heater.
Refer to the illustration below as a caution about handling the
terminals.
2 Fix the cable with cable ties to the cable tie mountings.
3 Configure the user interface for the respective power supply.
See "8.2.2 Quick wizard: Standard" on page 35.
During connection of the backup heater, miswiring is possible. To
detect possible miswiring, it is highly recommended to measure the
resistance value of the heater elements. Depending on the different
backup heater types, following resistance values (see table below)
should be measured. ALWAYS measure the resistance on the
contactor clamps K1M, K2M, and K5M.
