Matters Needing Attention
- For devices that are likely to cause a life-related accident or have a significant impact on the trial due to a timing switch error (e.g. medical equipment and large equipment etc.) please do not use this timing switch.
- For those equipment that have suffered significant property damage due to the error of the timing switch (such as large heat or cold storage, etc.), when using this timing switch be sure to use this timer switch with sufficient margins for the values of characteristics and performance, and take safety measures such as double circuits.
- Do not repair, disassemble or modify by yourself. For repairs, inspections, etc., please entrust the dealer or the user responsible for the construction.
- The switch operates in environments free of moisture, corrosion, and high metal content gases. Keep away from high-voltage lines, large transformers, and other places that interfere with remote control signals.
- Do not touch the terminal section after the power is turned on.
