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-poles type.
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.

10. Test run
• Refer to the “Test run” section of the installation manual of the indoor units and outdoor unit.
• When installation of the indoor unit, branch box, and outdoor unit is complete, begin test run to check for water leaks in the branch box.
• After power is supplied or after an operation stop for a while, a small clicking noise may be heard from the inside of the branch box. The electronic expan-
sion valve is opening and closing. The unit is not faulty.
• Be sure to perform the test run for each indoor unit. Make sure each indoor unit operates properly following the installation manual attached to the unit.
•
If you perform the test run for all indoor units at once, you cannot detect any erroneous connection, if any, of the refrigerant pipes and the indoor/outdoor unit connecting
wires.
*1 :Power supply cords of appliances shall not be lighter than design 60245 IEC or
60227 IEC.
*2 : In case that cable with stripe of yellow and green is available.
*3 : In case of regular polarity connection (S1-S2-S3), wire size is 1.5 mm².
*4 : In case of regular polarity connection (S1-S2-S3).
*5 : In the flat cables are connected as this picture, they can be used up to 55 m.
*6 : Mentioned cable length is just a reference value.
It may be different depending on the condition of installation, Humidity or
materials, etc.
Be sure to connect the outdoor-branch box/indoor-branch box connecting cables directly to the units (no intermediate connections).
Intermediate connections can lead to communication errors if water enters the cables and causes insufficient insulation to ground or a poor electrical contact at the in-
termediate connection point.
