Or electric shock may occur.
2.
Power cable used is to be selected according to
national regulations.
3.
An all-pole disconnection device which has at least
3 mm separation distance in all pole and a residual
current device (RCD) with the rating of above 10 mA
shall be incorporated in the fixed cable shall be
installed in accordance to national wiring regulations.
4.
Outdoor unit power cable should be selected and
connected according to the outdoor unit installation
manual.
5.
Cabling should be away from high temperature
components, or the insulation layer of the cable may
be damaged.
6.
Use wire clamp to fix the cables and terminal block
after connection.
7.
Communication cables should be wrapped together
