• The electrical power line and signal lines must be fastened tightly.
• Every indoor unit must have a 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 the
signal lines of the outdoor units grounded at one point.
• The whole length of the signal line should not exceed 1000m.

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

Definition principles of code switches:
SW01 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).
