Installation of Indoor Unit
In case of 1~230 V; 50 Hz connection it is not allowed to connect a secondary bridge between L2
to L3 or L1 to L3 in order to have 3x2 kW electrical heating capacity. Failure to comply may cause
internal overheating and fire hazard.
b) 3N ~ 400 V / 50 Hz on the connecting clips L1, L2, L3, N and PE (
).
Connecting clips of the supply cable
Connecting the communication cable
The communication cable is intended for the communication between the indoor and outdoor. For
the dimensions of the communication cable, see technical data.
It is important to correctly connect the cable to terminal block X5.
The communication cable connects the external device to the terminal terminals
X5
on the indoor
unit. It is necessary to connect the terminals
BUS–A, BUS–B
and
GND
and
10 V
.
The communication connection is considered as a low-voltage connection. The type of the
communication cable must be H05VV-F 4 x 0.75 mm
2
(IEC 60227-53) or similar.
Terminals L1, L2, L3 (3 x black or black, grey, brown cable)
