Transmission cable length limitation

Wiring example
The wiring depends on the system configuration. For details, refer to DATA BOOK.

Total wiring length: 500 m (1,640 ft) max. The maximum allowable wiring length of the M-NET transmission line for centralized control system and for Indoor/Outdoor system is shown in the formula below. Refer to the figure above for the alphabet in the formula. If the calculated wiring length exceeds the maximum value, M-NET signal cannot be sent to the end-device and communication/control cannot be made The maximum wiring length for local remote controller is 10 m (32 ft). The section that exceeds 10 m (32 ft) must be included in the total wiring length (500 m (1,640 ft) max.) Transmission line for centralized control: 200 m (656 ft) max. The maximum allowable wiring length from the power supply unit, which is on the transmission line for centralized control, to each outdoor unit and system controller is shown in the formula below. The value shows the maximum length that the power can be supplied to the transmission line for centralized control. If the calculated length exceeds the maximum value, the power cannot be supplied to the end- device and communication/control cannot be made. Indoor/Outdoor transmission line: 200 m (656 ft) max. The maximum allowable wiring length is shown in the formula below. The value shows the maximum length that the power can be supplied to Indoor/Outdoor transmission line. If the length exceeds the maximum value, the power cannot be supplied to the end-device and communication/control cannot be made.

Example for LOSSNAY

NOTES:

• If the total length of the remote controller’s wiring is less than 10 m (32 ft), use 0.75 mm² (AWG18) cable, and do not add their lengths to the length calculations made above.
• If the total length of the remote controller’s wiring is more than 10 m (32 ft), use 1.25 mm² (AWG16) cable or ø1.2 mm or more shielded cable for the length of wiring exceeding 10 m (32 ft), and be sure to add their lengths to the length calculations made above

Supply capacity to the transmission line

In order to ensure proper communication among the Outdoor unit, Indoor unit, LOSSNAY, and OA processing unit GUF-RD(H), and Controllers, the transmission power situation for the M-NET should be observed. In some cases, Transmission Booster should be used.

1. Terminal block 1 for transmission line (TB2) Power is not supplied to terminal block 1 for the transmission line. (Supply capacity: 0)
2. Terminal block 2 for transmission line (TB3) The power supply coefficient of terminal block 2 for the transmission line is 25. Refer to the latest DATA BOOK for details about the power consumption coefficient of the connected unit model
