Wiring diagrams
1) Be sure to wire correctly according to the terminal arrangement and wiring diagrams.
2) Please connect a fuse or a breaker to power supply part for safety reasons, to protect the
device and ease of maintenance.
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) Do not turn on the power supply or input until all wiring is completed.
