3.7 Electrical connection
3.7.1 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 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 10, page 66) 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 withthe
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 liveand 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.
▶ For devices with a fixed mains power supply in which the leakage
current is potentially higher than 10 mA, we recommend installing a
residual current device (RCD) with a maximum rated residual
operating current of 30 mA.
3.7.2 Connecting the indoor unit
The indoor unit is connected via a 4-wire communication cable. Use
cables of the type H07RN-F with sufficient conductor cross-section.
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.
Connecting the communication cable
▶ Remove the cover of the indoor unit 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.
3.7.3 Installation of display unit
▶ Put the buckles of the display board Fig. 22 into the grooves of
electric control box and push the display board down.
▶ Route the wire of the display unit through the cable clamp on the
electronic control unit and connect to the control board.
3.7.4 Connect the the wired room controller
NOTICE
Damage to the wired room controller or wiring
▶ Do not jam wires during installation.
▶ To avoid water entering the wired roomcontrollerwhen attachingthe
cabling (Fig. 25), use trap [2] and putty [1] to seal the plug-in
connector.
▶ Cables must be securely attached and must not be under tension.
NOTICE
Damage due to overvoltage
The wired room controller is designed for low voltage.
▶ Neverbringthecommunicationcable intocontact with high voltages.
Use the cable provided.
▶ If necessary, route an extension cable between the indoor unit and
installation location of the wired room controller.
▶ Connect the communication cable to the indoor unit.
▶ Where applicable, connect the communication cable with the wired
room controller via an extension cable. In doing so, insulate each
push fit connection with plastic hose and cable ties (Fig. 27).
▶ Fit the magnet ring.
▶ Connect the earthing terminal lug.
▶ Insert the button battery into the holder [1].
3.7.5 Connecting the outdoor unit
A power supply cable (3-wire) and the communication cable of the
indoor unit (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.
▶ Secure the communication cable to the strain relief and connect to
theterminals1(L), 2(N), Sand (assignment of wires to terminals
same as indoor unit) (Fig. 17 und 18).
▶ Attach 1 magnetic ring to the communication cable, as close as
possible to the outdoor unit.
▶ Secure power cable to the strain relief and connect.
– CL5000L ... E: terminals L, N and
– CL5000L ... E-3: terminals L1, L2, L3, N and
▶ Fasten cover for connections.
