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 unit.
▶ 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 unit.
3.5.2
Connecting the indoor unit
The indoor unit is 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
2
.
NOTICE
Material damage can be caused by connecting the indoor unit
incorrectly
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:
▶ Open the top cover and front cover.
– Release the locks on the top cover.
– Hold the top cover against your own body and lift.

▶ Connect protective conductor [2] to
.
▶ Note assignment of wires to the terminals.
▶ Reattach the cover of the switch on terminal.
▶ Fasten front and top cover again.
▶ Route the cable to the outdoor unit.
3.5.3
Connecting the outdoor unit
A power cable (3-wire) is connected to the outdoor unit and the
communication cable is connected to the indoor unit (4-wire).
Use cables of the type H07RN-F with sufficient conductor cross-section
and protect the mains power supply with a fuse (
Table 7).
Table 7
▶ Prepare the end of the power cable (
Fig. 18).
▶ Prepare the end of the communication cable (
Fig. 19).
▶ Remove the covers [3+6] of the electrical connection (
Fig. 20).
Model CLC6001i... only has the cover [3].
▶ Secure power cable [2] and communication cable [1] to the strain
relief [4]. If necessary, insert the supplied inlay [5] in-between.
▶ Secure power cable to terminals N, 1, and
.
▶ Secure the communication cable to terminals N, 1, 2 and
(assignment of wires to terminals same as indoor unit).
▶ Reattach the covers.
