Caution for Wiring
1) Terminal fastening torque should be 0.5 to 0.6N
･
m. In case of using a crimping terminal, use it with
insulating sleeve applicable to M3 screw.
2) This has no built-in power switch, circuit breaker for power supply part. To protect the device, it is
necessary to install power switch and circuit breaker in the power supply circuit.
And this has no built-in power switch, circuit breaker or fuse for measured voltage input parts.
Therefore it is necessary to install them in the circuit near this unit.
3) We recommend a wire with the cross section of 0.75 to 1.25mm
2
for power supply line and measured
voltage input line.
4) Use flame-resistant cable for each wiring.
