7-2. Connecting the Power Line and M-NET Transmission Line Tightening torque for terminal screws: 1 N·m Connect the device to a power supply unit (PAC-SC50KUA) for the transmission line or an outdoor unit (either a centralized control line or indoor control line can be connected). * Only the M-NET circuitry of this device receives the power from the M-NET transmission line. -
Page 9: Connecting The Signal Lines
7-3. Connecting the Signal Lines • Separately procure items such as terminal blocks and cables locally. • The maximum wire length is 100 m. However, since the use of long wires makes the device susceptible to noise, using wires shorter than 10 m is recommended. (1) Pulse input (non-voltage a contact) * To use these, various settings need to be configured. -
