Electrical Wiring
When the indoor units are controlled by the remote control, one can switch over the modes by
Switching Mode of Line-Controlled Main Unit/ Line-Controlled Sub Units/ Remote-Controlled Types.
The signal terminals need not be equipped with wires and connected to the line control.
Note: For DC motor low ESP duct, the PCB comes with the terminal Blocks. Pay attention to do
the wiring as per the specification. The Power lines and Signal lines go through the metal wire hole
separately with the protective sleeve of the connecting line.
The wiring for the power line of the indoor unit, the wiring between indoor and outdoor units, and the
wiring between indoor units:

• 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.
