5. Wiring (External Power Supply Type)
Please be sure to conduct the wire connection using the optional cable for external connection
as follows.
The main body and GND are electrically common.
Use an isolated power supply and a remote display as necessary.
Notes:
1. When installing the flow meter around an electric noise source, ground the braided
shield of the external connection cable.
2. Cut off the brown lead wire at its root to prevent it from contacting others.
3. Do not perform the insulation resistance and withstand voltage test.
