• The Power cable and the communication wire should be fixed firmly.
• Each connection kit must be earthed well.
• When the power cable exceeds the dimension range, ensure that you correct it appropriately.
• Shielded layer of communication wires should be connected together and be earthed at a single point.
• Communication wire's total length cannot exceed 1000 m.
Graphical representation for wiring
You need to connect the communication terminal block P and Q of the main unit of the outdoor units with the
communication terminal block P and Q of the first connection kit.

Notes:
(1) The above shown wiring example is only for reference. The number of connection kits and indoor units
shall determine the field installation.
(2) Two-core non-polar communication lines with shield shall be used for communication lines between the
connection kit and the indoor/outdoor unit.
(3) All connection kits within one system can share one over-current breaker for power supply. It is however
necessary to compute the total current capacity specification.
(4) In case of the wiring harness connected to the power terminal block, the terminal is to be pressed using a
round (refer to the following figure).
