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 an
authorised electrician.
▶ An authorised electrician must determine the correct conductor
cross-section and circuit breaker. The maximum current
consumption of the technical data ( see chapter 8, page 56) is
decisive for this purpose.
▶ Observe safety measures according to national and international
regulations.
▶ If you identify a safety risk in the mains voltage, or if a short circuit
occurs during installation, inform the operator in writing and do not
install the appliances , until the problem has been resolved.
▶ All electrical connections must be made in accordance with the
electrical connection diagram.
▶ Only use a special tool to cut cable insulation.
▶ Connect the cable to the existing mounting clips / cable glands using
suitable cable ties (scope of delivery).
▶ Do not connect any additional consumers to the mains power supply
of the device.
▶ Do not mix up live and PEN conductor. 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
input of the appliance.

Connecting the indoor unit
The indoor unit is connected to the outdoor unit using a 5-core
communication cable of the type H07RN-F. The conductor cross-section
of the communication cable should be at least 1.5 mm
NOTICE
Material damage due to incorrectly connected indoor unit
Voltage is supplied to the indoor unit via the outdoor unit.
▶ Only connect the indoor unit to the outdoor unit.
To connect the communication cable:
▶ Fold up the top cover ( Fig. 19).
▶ Undo screw and remove cover of the interface panel.
▶ Remove screw and cover [1] of the terminal ( Fig. 20).
▶ 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 W,
1(L), 2(N), S and
.
▶ Note assignment of wires to the terminals.
▶ Reattach the covers.
▶ Route the cable to the outdoor unit.

3.5.3
A power cable (3-core) is connected to the outdoor unit and the
communication cable is connected to the indoor unit (5-core). Use
cables of the type H07RN-F with sufficient conductor cross-section and
protect the mains power supply with a fuse ( Table 68).

▶ Undo the screw and remove the cover of the electrical connection
( Fig. 21).
▶ Secure the communication cable to the strain relief and connect to
the terminals W, 1(L), 2(N), S and
terminals same as indoor unit) ( Fig. 22).
▶ Secure power cable to the strain relief and connect to the terminals
L, N and
▶ Reattach cover.
