Safety precautions
WARNING
The SD24 Series digital indicators are designed to indicate temperature, humidity and other physical amounts for general industrial
equipment. You should either take appropriate safety measures or avoid using for control that could have a serious effect on human life.
The digital indicator should be housed in the control box, etc., to keep the terminal elements from being accidentally touched.
Do not remove the indicator from its case, or insert your fingers or electric conductors inside the case. Doing so could result in electric
shock accident involving death or serious injury.
Caution
If there is danger of damage to any peripheral device or equipment due to failure of the indicator, you should take appropriate safety
measures such as mounting a fuse or overheating prevention device.
An alert
symbol is printed on the terminal nameplate applied to the case. Alert marks are provided to call your attention to the fact
that you could be shocked if you touch charged parts.
Provide a switch or breaker as a means of cutting off power for external power circuit connected to the power terminal of the indicator.
Mount a switch or breaker near the indicator where the operator can get to it easily and label it as an electrical breaker for the indicator.
