▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
sc
is
greater than or equal to the minimum S
sc
value at the interface
point between the user's supply and the public system.
▪ 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.
▪ 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 short-circuit power S
sc
greater than or equal to the
minimum S
sc
value.

5.4.2 Safety device requirements
The power supply must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage protector in accordance with the applicable legislation.
Selection and sizing of the wiring should be done in accordance with
the applicable legislation based on the information mentioned in the

For all models:
▪ Phase and frequency: 3N~ 50 Hz
▪ Voltage: 380-415 V
▪ Transmission line section:
Transmission wiring Vinyl cords with 0.75 to
1.25 mm² sheath or cables
(2‑core wires)
Maximum wiring length

If the total transmission wiring exceeds these limits, it may
result in communication error.
6 Installation
6.1 Overview: Installation
This chapter describes what you have to do and know on-site to
install the system.
Typical workflow
Installation typically consists of the following stages:
▪ Mounting the outdoor unit.

▪ Connecting the refrigerant piping.
▪ Checking the refrigerant piping.
▪ Charging refrigerant.
▪ Connecting the electrical wiring.
▪ Finishing the outdoor installation.
▪ Finishing the indoor installation.
INFORMATION
For installation of the indoor unit (mounting the indoor unit,
connecting the refrigerant piping to the indoor unit,
connecting the electrical wiring to the indoor unit …), see
the installation manual of the indoor unit.
6.2 Opening the units
6.2.1 About opening the units
At certain times, you have to open the unit. Example:
▪ When connecting the refrigerant piping
▪ When connecting the electrical wiring
▪ When maintaining or servicing the unit
DANGER: RISK OF ELECTROCUTION
Do NOT leave the unit unattended when the service cover
is removed.
