In case of wired type only
Up to 500 m
In case of wireless type included
Up to 400 m
Total wire length of wired remote controller inter-unit wiring = L1 + L2 + … Ln

CAUTION
•
The remote controller wire (Communication line) and AC 208-240V 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 or other factor.
• If U series models (TU2C-Link) are combined with models other than U series (TCC-Link), the wiring
