6. Wiring

• Use a cable of 1.25 mm

to 2 mm

diameter, and suitable for the environmental conditions in which

it is to be used.

• Connect wires only to the AC (power supply) and to 4 mA to 20 mA (current output) terminals.

Caution:

Do not connect unused terminals, as this may result in a Flow Monitor failure.

Caution:

Be sure to confirm that the power supply has been turned off before
connecting the wiring. Failure to observe this precaution may result in an
electric shock, electric leakage, fire or other accident.

IMPORTANT: If the Flow Monitor is used in an environment where electrical noise is

generated, use a protective metal conduit tube for the cable to prevent
malfunction caused by electrical interference.
