For low-voltage circuits, grounding of the secondary sides of the instrument voltage transformer and current transformer is unnecessary.
Make sure to use after grounding the earth terminal ( ). Provide a D earth (earth resistance: 100Ω or less) for grounding. Inadequate grounding may
cause a malfunction.
As the lead wires for connecting the output and load of a transducer, use two-core shielded wires or twisted-pair wires to prevent malfunction and failure
due to transmission noise and disturbance surge. If the transmission distance exceeds 100m, current output specifications are recommended.
Do not bring the output line close to or bundle it together with other power lines or the input lines (VT, CT, and auxiliary power supply).
Ground the shield line of a shielded cable on the receiving side.
However, depending on the circumstances of external noise, it may be better to ground it on the transducer side.
