• The electrical power line and signal lines must be fastened tightly.
• Every indoor unit must have the ground connection.
• The power line should be enlarged if it exceeds the permissible length.
• Shielded lays of all the indoor and outdoor units should be connected together, with the shielded lay at the side of signal
lines of outdoor units grounded at one point.
• It is not permissible if the whole length of signal line exceeds 1000m.

• The shielding lay of the signal line must be grounded at one end.
• The total length of the signal line shall not be more than 250m.

Definition principles of code switches:
SWO1 is used to set capabilities of master and slave indoor units as well as indoor unit; SW03 is used to set indoor unit
address (combine original communication address and address of centralized controller).
