2. Use feed wiring to connect terminals M1 and M2 on transmission cable terminal block (TB3) for the outdoor unit (OC) to terminals M1 and M2 on the transmission cable

terminal block (TB5) of each CITY MULTI series indoor unit (M-IC). Use nonpolarized 2-core wire.

3. Connect terminals 1 and 2 on transmission cable terminal block (TB15) for each CITY MULTI series indoor unit with the terminal block for the MA remote controller

(MA-RC).

I Permissible Lengths

1. Maximum transmission cable length between indoor and outdoor unit:

L1 + L2 ≤ 200 m [656 ft] (1.25 mm² [AWG16] or more)

2. MA remote controller cable length:

1, 2 ≤ 200 m [656 ft] (0.3 to 1.25 mm² [AWG22 to AWG16])

Note:

Combinations of standard operation, operation using 2 M-NET remote controllers, and group operation are possible.

I Wiring Method and Address Settings

1. Always use shielded wire when making connections between the outdoor unit (OC) and the indoor unit (M-IC).

2. Use feed wiring to connect terminals M1 and M2 on transmission cable terminal block (TB3) for the outdoor unit (OC) to terminals M1 and M2 on the transmission cable

terminal block (TB5) of each CITY MULTI series indoor unit (M-IC). Use nonpolarized 2-core wire.

3. Connect terminals 1 and 2 on transmission cable terminal block (TB15) for each CITY MULTI series indoor unit with the terminal block for the MA remote controller (MA-

RC).

4. In the case of using 2 remote controllers, connect terminals 1 and 2 on transmission cable terminal block (TB15) for each indoor unit with the terminal block for 2 MA

remote controllers.

• Set either one of the MA remote controllers to "sub remote controller".

• Refer to the Installation Manual of MA remote controller.

I Permissible Lengths
