   Caution:

After using the isolator, be sure to turn off and on the main power supply to reset the system. Otherwise, the outdoor unit may not be able to detect the 

branch box(es) or indoor units.

 Warning:

In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between power 

line and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power 

is energized. If isolator should be used between outdoor unit and branch box/indoor unit and branch box, please use 3-pole type.

8. Electrical work

  Power supply wiring (Supply power separately to branch box 

and outdoor unit)

•  Install an earth line longer than other cables.

•  Power supply cords of appliance shall not be lighter than design 

45IEC57 or 

7IEC57, 45 IEC 53 or 7 IEC 53.

•  A switch with at least 3 mm, 1/8 inch contact separation in each pole shall be 

provided by the air conditioner installation.
