device of the building by the professional.
The electric installation should be carried out by the professional as instructed by the local laws,
regulations and also this manual.
The air switch coupled with the leakage current protection switch must be equipped in the circuits, which
is of enough capacity and of both magnetic and thermal tripping functions in case of the short circuit and
overload.
The power supply of the outdoor unit and all the DB modules should be separately.
The electrical work should use a cable length enough to cover the entire distance with no connection. If it
is unavoidable, please make sure the connection should be reliable, the external forces will not act on the
wires and the joint is not bared. Otherwise it will cause electrical shock or fire etc.
The power cable with the rated voltage and exclusive circuit for the air conditioning should be used.
Do not pull the power cable by force after it is installed.
The diameter of the power cable should be large enough and once it is damaged, it must be replaced by
the dedicated one.
The multi-wire copper cable should be used for the power cable and the transmission line.

Caution
!
The transmission line and the power cable must be separated and separated with an interval of at least
2cm; otherwise it may be
result in communication problem.
