6.3 Caution for Wiring
1) Terminal fastening torque should be 0.5 to 0.6N・m for M3 screw and should be 1.0N・m for M3.5
screw. In case of using a crimping terminal, use it with insulating sleeve applicable to M3 screw or
M3.5 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 1.25mm2 for power supply line and
measured voltage input line.
