It is recommended to use the 20 AMG (0.52mm

) cable as the control condenser start / stop
signal cable.
•
Outdoor cable between indoor unit and the condenser need to be shielded by protected pipes.
•
The cables should not be in contact with any hot object. Over-current protective device or simi-
lar device should be provided in the installation circulation (select as shown in Table 2-4).
2. Connect the Cables
External power cable and compressor signal cable are connected from No.1 system and No.2 system
respectively, for specific wiring details refer Figure 2-12 and Appendix-I Circuit Diagram for the connections
of external power cables. To protect against
the thunderstorm conditions, grounding line must be connected
with the bolt of condenser lighting protection connection in the electrical control box of No.1 system and No.2 system
respectively.
