2. Wiring method for M-NET
Caution for wiring
1 Never supply voltage 208V-230VAC to the terminals for M-NET transmission. If the voltage is supplied,
it can break the electronic parts on the M-NET board.
2 Use the shielded cable (CVVS, CPEVS, MVVS) of 1.25mm² (AWG 16) with 2 wires (polarity is
not a concern) for the transmission cable.
Never use transmit wires of different system with a cable which contains multi wires.
The communication of transmit signals will not work properly and it can cause wrong operation.
3 The power consumption coefficient
w1 "Power consumption coefficient" is a coefficient to calculate the relative power
consumption of the devices that receive power through the M-NET transmission cable.
