Wired remote controller wiring, remote controller inter-unit wiring Wire size: 0.5mm² to 2.0mm²
Total wire length of wired remote controller wiring and remote
controller inter-unit wiring = L + L1 + L2 + ... Ln
Total wire length of wired remote controller inter-unit wiring = L1 + L2 + ... Ln
The remote controller wire (Communication line) and AC220–240V wires cannot be parallel to contact
each other and cannot be stored in the same conduits. If doing so, a trouble may be caused on the control
system due to noise, etc.
