incorrectly
Voltage is supplied to every indoor unit via the outdoor unit.
▶ Only connect the indoor unit to the outdoor unit.
▶ Remove the cover of the indoor unit electronics.
▶ Connect the cable of the cover and the communication cable to the
indoor unit ( Fig. 26) and secure to the strain relief.
– Plug the cables of the cover into the connections provided.
– With several product types, connect the communication cable to
the terminals L, N, S and
1)
.
– If necessary, connect other accessories.
▶ Note assignment of communication cable wires to the terminals.

3.6.3 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
the terminals 1(L), 2(N), S and (assignment of wires to terminals
same as indoor unit) ( Fig. 18 and 19).
▶ 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.
3.6.4 Connection as twin combination
With the twin combination, two indoor units are connected in series.
With the slave unit, terminal S is omitted. Instead of that, communication
takes place between he indoor units via terminals X, Y and E.
Key to Fig. 31 and 32:
IDU-M Master unit (indoor unit 1)
IDU-S Slave unit (indoor unit 2)
▶ Connect master unit as described in chapter 3.6.2.
▶ Connect save unit to the master unit via terminals L, N and
2)
.
▶ Connect master unit and slave unit additionally to terminals X, Y and
E via a communication cable. In doing so, earth the shield.
The central controller and twin combination both use the X/Y/E terminal.
For this reason, a decision must be made in advance if a twin
combination or central controller is installed.
