Matters that could result in equipment damage if instructions are not followed.
CAUTION
additional instructions and notes
Note
PAC18A Series instrument is designed to control heater power, etc., used by industrial equipment. It should not be used for nuclear power generation, traffic
control, communications or medical equipment. You should either take appropriate safety measures or avoid using for control that could have a serious
effect on human life. The manufacturer shall not be liable for an accident that results if used without taking appropriate safety measures.
1. The power regulator should be used so the terminal elements in the control box, etc., are not touched by human beings.
2. The power regulator should not be used as a switch.
Even if output is zero, power is present in the capacitors and resistors of the output circuit, and could result in accident involving human life or serious
bodily injury due to electrical shock.
3. Radiation fins and chassis become extremely hot. Never touch the radiation fins or chassis. Doing so could result in burn injury.
4. Do not supply power when wiring. Doing so could result in electrical shock.
5. Do not touch terminal elements or other charged parts while conducting electricity. Also, do not introduce foreign objects or matter into the equipment.
If a foreign object or matter accidentally gets inside, be sure to turn off the power and make sure all is safe before introducing tools or your hands.
If there is danger of damage to any peripheral device or equipment due to failure of the power regulator, you should take appropriate safety measures such
as mounting a rapid fuse or overcurrent circuit breaker.
1. Concerning the
alert symbol on the power regulator's plate, a
The symbol is provided to prompt you to employ special care not to touch the device because doing so could result in electrical shock if parts that
conduct power are touched when power is present, or could result in burn injury if touched when hot, etc.
2. Provide a switch or breaker as a means of cutting off power for external power circuit connected to the power terminal of the device.
Mount a switch or breaker near the controller where the operator can get to it easily and label it as an electrical breaker for the device.
3. Be sure to securely fasten conductor cable connections before using.
Failure to do so could result in burning from overheating due to contact resistance.
4. Be sure power supply voltage and frequency do not exceed the rating.
5. Do not apply voltage/current other than rated input to the input terminal.
Doing so could shorten the life of the product or result in equipment failure.
6. Voltage/current of load connected to the output terminal should not exceed the rating.
Using voltage/current that exceeds the rating could shorten the life of the device by raising the temperature, and could result in equipment failure.
7. Be sure to mount the terminal cover that comes with the device after wiring.
8. The user should absolutely not modify or use the device in any way other than it was intended to be used.
9. To ensure safety and maintain the functions of this device, do not disassemble this device. If this device must be disassembled for replacement or repair,
contact your dealer.
10. Be sure to observe the notes and precautions provided in the manual to use the device safely and maintain its reliability.
Note: Shimaden shall bear no responsibility, monetarily or otherwise, for accident or damages caused by failure to observe warnings, notes and precautions
contained in the instruction manual.
