Electric characteristics
Control wire
Remote control wiring
• 2-core with non-polarity wire is used for wiring of the remote control wiring and group remote controls
wiring.
NOTE
• Use copper supply wire.
• Use UL wire rated 600V for the power supply.
• Use UL wire rated 300V for the remote control wires and control wires.
CAUTION
The remote control wire (Communication line) and AC208/230V 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.
