• 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 per miss ible 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 onepoint.
• The whole length of the signal line should not exceed 1000m.

• The shielding lay of the signal line must be grounded at oneend.
• The total length of the signal line should not be more than250m.

Indoor Units PCB
In the following table, 1 represents ON and 0 represents OFF. Definition principles of code switches:
SWO1 is used to set the capabilities of the master and slave indoor units as well as the indoor unit; SW03 is used to set
the address of the indoor unit (combine original communication address and address of centralized controller).
