Example of wiring:
Note: The wire length from indoor unit to the external interface must be within 1.9 meters. The wire must be double
insulation type and a ferrite core to be added to reduce noise. Proposed core spec is J0KE00000147 with Heat
Shrinkage Tube.
The signal between indoor unit and the external interface must be isolated by photo-coupler of approval type (e.g:
Semko, VDE etc).
