Important Handling Precautions
- 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.(Copal 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.
