* Communication cables are required to be separated from the power supply wiring and other electrical device
wiring. Keep at least 12 inches (31cm) between communication cabling and the power supply wiring. If the
above is not secured, put the power supply wirings and communication cabling into the each metal conduit tube
separately. One side of the metal conduit tubes should be grounded for noise reduction.
* Do not connect the power supply wiring to the terminals for transmission of the mini central controller.
If the power supply wires are connected incorrectly, the fuse of the printed circuit board will short-circuit. If this

* Remove the ground wiring for the frame ground (FG) terminal when the insulating capacity test or the withstand
voltage test is performed. It may prevent operation of the mini central controller.
