General notes

WARNING
Risk to life from electric shock!
Touching live electrical parts can cause an electric shock.
▶ Before working on electrical parts, disconnect all phases of the
power supply (fuse/circuit breaker) and lock the isolator switch to
prevent unintentional reconnection.
▶ Work on the electrical system must only be carried out by a qualified
electrician.
▶ Observe safety measures according to national and international
regulations.
▶ If there is a safety issue with the power supply or if there is a short
circuit during installation, inform the customer in written form and do
not install the unit until the issue is resolved.
▶ All electrical connections must be made in accordance with the
electrical connection diagram.
▶ Only strip cable insulation with the correct tools.
▶ Do not connect any additional loads to the mains power supply of the
device.
▶ Do not mix up live and neutral wires. This can lead to malfunctions.
▶ If the mains power supply is fixed, install an overvoltage protector
and isolator which is designed for 1.5 times the maximum power
consumption of the device.

Connecting the indoor unit

The indoor units are connected to the outdoor unit using a 4-wire
communication cable of the type H07RN-F. The conductor cross-section
of the communication cable should be at least 1.5 mm
Every connection pair of the pipes has a corresponding electrical
connection.
▶ Connect every indoor unit to the corresponding terminals ( Fig. 6).
NOTICE
Material damage can be caused by connecting the indoor unit
incorrectly
Voltage is supplied to every indoor unit via the outdoor unit.
▶ Only connect the indoor unit to the outdoor unit.
Wall-mounted indoor unit
To connect the communication cable:
▶ Fold up the top cover ( Fig. 26).
▶ Undo screw and remove cover of the interface panel.
▶ Remove screw and cover [1] of the terminal ( Fig. 27).
▶ Knock out an opening for the cable feed [3] on the rear of the indoor
unit and feed the cable through.
▶ Secure cable to the strain relief [2] and connect to the terminals L, N,
S and .
▶ Note assignment of wires to the terminals.
▶ Reattach the covers.
▶ Route the cable to the outdoor unit.
Built-in ducted indoor unit
To connect the communication cable:
▶ Remove the cover of the electronics.
▶ Secure cable to the strain relief and connect to the terminals L, N, S
and .
▶ Note assignment of wires to the terminals.
▶ Reattach the covers.
▶ Route the cable to the outdoor unit.

Cassette indoor unit
▶ Remove the cover of the electronics.
▶ Connect the cable of the cover and the communication cable to the
indoor unit ( Fig. 37) and secure to the strain relief.
– Insert the cable of the cover into the 5-pin and 10-pin terminal.
– Connect the communication cable to the terminals L, N, S and
▶ Note assignment of communication cable wires to the terminals.
▶ Hook in air inlet grille on one side ( Fig. 36).
▶ Reattach the cover of the electronics and close the air inlet grille
( Fig. 38).
▶ Route the cable to the outdoor unit.
3.6.3
A power supply cable (3-wire) and the communication cable of the
indoor units (4-wire) are connected to the outdoor unit. Use cables of
the type H07RN-F with sufficient conductor cross-section and protect
the mains power supply with a fuse ( Tab. 15).
