(1)  Select the cable run location so they are away from electrical equipment (motors, transformers, 

or radio transmitters) which causes electromagnetic or electrostatic interference. 

(2)  Deterioration of flowmeter circuit insulation occurs if the converter interior or cable ends get wet 

or humidified. This in turn causes malfunction of flowmeter or noise problems. Avoid a rainy 
day if the flowmeter is to be installed outdoors. Even indoors, prevent water from splashing over 
the flowmeter. Try to finish the wiring as quickly as possible 

(3)  The converter has a surge arrestor/protector installed inside. Therefore, do not conduct a 

withstand voltage test for the converter. To check the insulation of the converter, use a voltage 
of 250Vdc or less. 

(4)  After wiring, be sure to install the terminal block protection cover. 

 

Use the kind of cables shown in Table 5.1 to wire the converter.
