3.5 Electrical connection
3.5.1 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.
The outdoor and indoor units must only be connected to a mains power
supply with limited network impedance ( Table 7). If necessary, ask
your utility company what the network impedance is.
Table 7 Maximum network impedances
3.5.2 CLL2000-Set 23/26/35/53 W: connecting the cables
A power cable is available at the indoor unit. The indoor unit and outdoor
unit are connected via a 5-wire communication cable. Use cables of the
type H07RN-F with sufficient conductor cross-section and protect the
mains power supply with a line fuse ( Table 8).
Table 8
Connecting the indoor unit
▶ 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 communication cable through.
▶ Secure communication cable to the strain relief [2] and connect to
the terminals 1(L), 2(N), 3, 4 and .
▶ Note assignment of wires to the terminals.
▶ Reattach the covers.
▶ Route the cable to the outdoor unit.
Connecting the outdoor unit
NOTICE
Material damage can be caused by connecting the outdoor unit
incorrectly
Voltage is supplied to the outdoor unit via the indoor unit.
▶ Only connect the outdoor unit to the indoor unit.
▶ Undo the screw and remove the cover of the electrical connection
( Fig. 22).
▶ Secure the communication cable to the strain relief and connect to
the terminals 1(L), 2(N), 3, 4 and (assignment of wires to
terminals same as indoor unit) ( Fig. 23).
▶ Reattach cover.
3.5.3 CLL2000-Set 70 W: connecting the cables
A power cable (3-wire) is connected to the outdoor unit. The indoor unit
and outdoor unit are connected via a 4-wire communication cable. Use
cables of the type H07RN-F with sufficient conductor cross-section and
protect the mains power supply with a line fuse ( Table 9).
Table 9
Connecting the indoor unit
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.
▶ Fold up the top cover ( Fig. 9).
▶ Undo screw and remove cover of the interface panel.
▶ Remove screw and cover [1] of the terminal ( Fig. 21).
▶ Knock out an opening for the cable feed [3] on the rear of the indoor
unit and feed the communication cable through.
▶ Secure communication cable to the strain relief [2] and connect to
the terminals 1(L), 2(N), S and .
▶ Note assignment of wires to the terminals.
▶ Reattach the covers.
▶ Route the cable to the outdoor unit.
