TSURUGA ELECTRIC CORPORATION
■
Connections
Measuring input terminals of the instrument and,
the contact output and auxiliary supply terminals M3.
Make firm and correct connections with crimp type terminal.
Optimum torque of the terminal screws: 0.36~0.48N

Note :
In case that the model name is NRC-100H, no contact output
terminals for the low limit is provided.
●
Measuring Input Terminals
Arrange a cabling of measuring input line and power source line as
distant as possible from each other. Close and parallel wiring of these
two lines may cause unstable reading of the instrument.

●
High Limit (HIGH) and Low Limit (LOW) Contact Output Terminals
The contact capacity of high and low limit contact output is, with resistive load: AC250V, 3A or DC30V, 3A
Make the connections with the cable conforming to these capacities. In case that the relay controls with the capacity higher than
these, provide the auxiliary relay externally.
