Use cables H03VV-F 4x0.75 mm 2 to connect the control to wire NUI and H03VV-F 6x0.75 mm
Also check the supply voltage and frequency of the indoor unit.
Remove the front panel, the electric parts appear at the
front side.
The power supply cables can be inserted into the pipe
holes. Be sure to fix the power cable with bundling band
sold in the market so that they do not make contact with
the compressor and the hot pipes.
To ensure good tensile strength, the electric cables must be
fastened using the cable-holder on the plate.
(Only for sizes 12 and 15 use the strain relief supplied with
the unit). See fig 16 for power supply cabling.
Wired control For installation of wired remote controller please refer to the control installation manual.
Power supply Size the cable, the cables must be H07 RN-F type.
According to the installation instructions, all devices for disconnection from the power supply mains must have a contact opening (4 mm) to allow
total disconnection according to the conditions provided for the overvoltage class III.
To prevent any risk, the power cable must only be replaced by the technicians of the after-sales service.
WARNING For the 3Ph units be sure to attach the provided clamp filter (11) to the power supply wire in order to conform to EMC standard. (See fig 17).
