7.6.2 About electrical compliance
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.).
Only for the backup heater of the indoor unit
See "7.6.9 To connect the backup heater power supply" on
page37.
7.6.3 Precautions when connecting the
electrical wiring
INFORMATION
Also read the precautions and requirements in the
following chapters:
▪ General safety precautions
▪ Preparation
DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
7.6.4 Guidelines when connecting the electrical
wiring
Keep the following in mind:
▪ If stranded conductor wires are used, install a round crimp-style
terminal on the end of the wire. Place the round crimp-style
terminal on the wire up to the covered part and fasten the terminal
with the appropriate tool.

maximum values (see electrical data of combination with
indoor units for exact values).
(b) The minimum allowed field fuse is 20 A.
NOTICE
It is possible to install a field fuse with lower than
recommended rating over the heat pump. For this you
must modify field setting [2‑0E] according to the maximum
allowed current over the heat pump.
Note that field setting [2‑0E] overrules all power
consumption control settings. Power limiting the heat pump
will reduce performance.
7.6.6 To connect the electrical wiring on the
outdoor unit
1 Remove the switch box cover. See "7.2.2To open the outdoor
unit"on page28.
2 Strip insulation (20mm) from the wires.
