8. 2 Wiring diagram
For you reference, the example of wiring of the gateway unit CN1 is shown below.
The communication line from the gateway unit CN1 branches to each controller (LEC) by the branch
connector. It is recommended to connect the terminating resistor (120
Ω
1/4W) to the branch connector
at the terminal.
When connecting the cable, the shield of the cable becomes same potential as 0V of the controller
power supply.
When using it, do not contact it to conductive parts of switchboard, other instruments, wiring, etc.
