Never insert any foreign matters except specified pressure media into the pressure port, as this may alter the performance characteristics or damage the diaphragm, and cause malfunctions.
Tighten wiring opening with the supplied cable gland for avoiding water intrusion.
The cable gland and/or lid may get loose in certain usage environments　and the sealing level may lower as a result. So please use a locking nut or tighten regularly.
Atmospheric pressure is released through wiring cable.(Nidec Components recommends a cable with built-in atmospheric-pressure-releasing tube)
Cable wiring should be conducted in the state of power off. Shorting the output terminal and power terminal will damage the internal circuit.Please be careful not to wire incorrectly.
