WIRING WORK

Power supply cable arrangement

Connect the ring terminal of 3phase cable (CV)

•   Do not let the power supply cable come into contact with the pipes inside the 

outdoor unit.  
If the power supply cable touches the pipes, the vibration of the compressor is 
transferred to the pipes and can damage the power supply cables or pipes, creating 
the danger of fire or explosion.

•   Make sure that the place where the sheath of power supply cable is removed is 

inside the power supply box. If it is impossible, you should connect the protective 
tube of power supply cable to the power supply box. 

•  After positioning the power supply cable into the power supply box, tighten the cover.

CAUTION

Earth

1. 

Tailor the power cable according to its length and connect it with the solderless terminal.

2. 

After connecting the power cable to the terminal as seen in the picture, fix it with cable tie.   

3. 

Fix the housing which has an insulator to the terminal board.
