4.6.21 Power Source Connection and Grounding
Connect DC power supply of FT-112(D) Panel to the noise proof power line due to the weighing instrument
measures very low signal levels. The quality of the power line and DC power supply will determine the
accuracy and the safety of your measuring system. The instrument should not share power lines with noise-
generating parts such as heavy load switching relays, motor control equipment, inductive loads, etc. If the
condition of the power supply in the plant is poor, prepare a special power line and grounding. Before
connecting the power, source check its voltage and be sure that it is the same with the voltage written on the
weighing indicator.
