5.3.2 Precautions when connecting the
electrical wiring
INFORMATION
Also read the precautions and requirements in the
following chapters:
▪ General safety precautions
▪ Preparation
DANGER: RISK OF ELECTROCUTION
Do NOT turn on the power supply (both the power supplied
by the indoor unit to X3A and the detection voltage
supplied to X1A) before you have connected all the wiring
and closed the adapter.
NOTICE
To prevent damage to the PCB, it is NOT allowed to
connect the electrical wiring with the connectors already
connected to the PCB. First connect the wiring to the
connectors, then connect the connectors to the PCB.
WARNING
To prevent damage and/or injury, do NOT make any
connections to X1A and X2A on LAN adapter BRP069A62.
5.3.3

To connect the indoor unit

INFORMATION
▪ In the indoor unit switch box, the cable is connected to
the same terminals the user interface is connected to
(P1/P2). For more information, see the installation
manual of the indoor unit.
▪ The 2 wires from the cable are NOT polarised. When
connecting them to the terminals, their polarity does
NOT matter.
1 When entering the wiring from the bottom: inside the LAN
adapter casing, ensure strain relief by routing the cable along
the indicated cable path.
2 Connect indoor unit terminals P1/P2 to LAN adapter terminals
X3A/1+2.
