Caution: Perform wiring so that the
terminal block is not strained.
If strained, use a wire guide or
junction terminal to alleviate the
stress on the terminal block.
Note:
• The input signal line should not come
into contact with or be installed
alongside the M-NET transmission line
and power supply line.
• Connecting an Uninterruptible power
supply (UPS) to the 24 VDC power
supply is recommended in order to
prevent the loss of pulse data in the
event of a power failure.
* The wiring in the diagram has been simplified.
