ELECTRICAL WIRING
●
Where power supply cable is connected through junction box in series, be sure to determine the total current and choose wires based
on the table below.
Selection according to EN 60335-1.
●
As a minimum, the chosen wires shall not be lighter than the polychloroprene sheathed flexible cord (code designation 60245 IEC 57).
●
The wiring specifications for weak-current communication circuit shall not be lower than that for RVV(S)P shielded wires or equivalent,
and the shielding layer shall be grounded.
●
A switch that can ensure all-pole disconnection shall be installed between power supply and air conditioning unit in such a manner that
the contact spacing shall not be less than 3 mm.
●
Once the power cord is damaged, the dealer or the professionals from designated maintenance department must be contacted in a
timely manner for repair and replacement.
●
For the installation of power cord, the ground wire must be longer than the current-carrying conductor.
