Wiring connection

NOTE
• When performing transition wiring for the remote controllers, polarity is not needed to be considered when connecting
wires to the terminal A and B on the indoor unit terminal block.
• Leave an extra length of 100 mm for each wiring so that servicing can be performed more easily.
• Low voltage circuit is applied for the remote controller.
Perform wiring so that each wire corresponds with the proper terminal number; otherwise, an electrical fault may
occur.
Wiring in the electrical control box of the indoor unit
Fix the wires using a cord clamp. Do not stretch them tight for wiring.
