(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
less than or equal to Z
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
Z .

1 Connect the backup heater power supply. For *3V models, a
double‑pole fuse is used for F1B. For *9W models, a 4‑pole
fuse is used for F1B.
2 If required, modify the connection on terminal X14M.

Special remark for terminals:
As mentioned on the table above, the connections on the terminals
is
X6M and X7M need to be changed to configure a backup heater.
Refer to the illustration below as a caution about handling the
terminals.
3 Fix the cable with cable ties to the cable tie mountings.
INFORMATION
For more information on the backup heater types, and for
how to configure the backup heater, refer to the
"Configuration" chapter of the installation manual of the
outdoor unit.
During connection of the backup heater, miswiring is possible. To
detect possible miswiring on the *9W model, 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.
K1M/1 K5M/13
K1M/3
K1M/5
K1M/3 K1M/5
K2M/1 K5M/13

K2M/3 K2M/5
K1M/5 K2M/1
Example measure resistance between K1M/1 and K5M/13:
