NOTE
Use copper supply wire.
Use UL wire rated 600 V for the power supply.
Use UL wire rated 300 V for the remote control wires and control wires.
CAUTION
The remote control wire (Communication line) and AC208 / 230 V 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.
