In terms of safe installation, the AWO BUS
connection (43 V / 12 V) is not low voltage and
must be routed together with the 230 V/400 V
cable.
Do not interchange wires L and N on the mains
connection. If wires L and N of the mains
connection are interchanged, the AWO BUS may
carry mains voltage, leading to appliance damage.
Only one BUS connection may be connected.
The wires of the AWO BUS connection between
the indoor and outdoor module must not be
interchanged.
