 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.
 NC is a connection-forbidden terminal.
