• Ensure that wiring is done correctly. Failure to do so might result in fire, burns, or electrical shock.
• Never use in explosive atmospheres, as doing so might result in fires, burns, or bodily injury.
• Do not operate the product with live parts exposed. Doing so might result in electric shock.
• Only use the product integrated with another device or system. Failure to do so may result in burns or electrical shock.
• Do not touch the product while it is operating. Otherwise, it may result in burns or electrical shock.
• Turn off the power and stop using the product immediately if you notice any sparks, smoke, odd odors or sounds, or anything unusual during operation. Failure to do so might result in fire, bodily injury, or electrical shock.
• Never allow the product to fall, topple over, or be subjected to excessive shocks when moving it. Doing so might result in product failure or performance deterioration.
• The product should be handled by technically qualified personnel or someone with sufficient expertise; the personnel shall be assigned at your own discretion.
• Never attempt to disassemble, repair, or alter the product in any way, as doing so might result in electrical shock, fire, or bodily injury.

Caution

Handling

• Discharge static electricity from your body before handling the product. In addition, avoid packaging or covering the product with materials which generate static electricity. Contact with static electricity may result in product failure.
• Do not touch solder joints or pins. Otherwise, it may result in bodily injury.
• Installation, mounting, connections, wiring, and relocation of the product should be done by technically qualified personnel or someone with sufficient expertise; the personnel shall be assigned at your own discretion. Never perform such work while the product is on, as this might lead to injury, electrical shock, burns, or fire.
• Never allow yourself to come into contact with the product when measuring insulation resistance or dielectric strength. There is danger of electric shock.
• Never attempt to disassemble or alter the product in any way. Doing so might not only result in substandard performance, but also fire, burns, bodily injury, or electrical shock.

Operation

• Do not touch the product for a period after the power has been turned off as it may still be hot. Otherwise, it may result in burns.
• Take protective measures for the equipment in which the product is embedded in case the product stops, malfunctions, or fails during operation.
• Never use the product at voltages, temperatures, or any other parameters exceeding those given in the product specifications.
  Otherwise, it might result in substandard performance, failure, fire, bodily injury, or electrical shock.
• Do not remove the nameplate. Doing so might result in product failure or electrical shock.
• Do not turn the power on or off on the negative power line. Doing so might damage the product.
• Do not apply excessive force to the product while it is operating. Otherwise, it may result in product failure.

Installation

• When fixing the product into place, be sure to take into consideration the product’s weight and all other relevant factors. Failure to do so may result in the product or its parts falling, resulting in bodily injury or device failure.
• Never install or remove the product while it is wired.
• When fixing the product with screws, ensure correct tightening torque. If the tightening torque is over the recommended values, the product structure may deform or break.
• Install the product carefully without touching conductors or other electrical components. Touching these components may result in device failure, product failure, or product malfunction.
• Take proper precautions against static electricity when wiring. Failure to do so might cause failure of the product or equipment.
• Make connections correctly in accordance with the information of this Instruction Manual and the nameplate of the product. Failure to do so might result in equipment failure or the malfunction, failure, or performance degradation of the product.
• Ensure that wires are fitted with insulation to prevent accidental short-circuiting. Failure to do so may result in device failure, product failure, or product malfunction.

Operating Environments

• Avoid using or storing the product in the following environments. Otherwise, it might result in fire or the failure or performance degradation of the product.
  In environments where flammable or corrosive gas is present, where water or oil splashes, where there is much dust or humidity, where condensation occurs, where exposed to radioactive rays or direct sunlight, where a salty sea breeze blows or seawater splashes, where the product might be contaminated by such corrosive materials as sulfurous water, sulfurous volcanic ash, organic solvents, acidic and alkali chemicals, or nuclear fuel materials, where subjected to constant vibration, strong shocks, centrifugal force, acceleration, or strong magnetic force, where electromagnetic noise radiation is present, where the electromagnetic noise overlaps into power voltage, or where subjected to rapid environmental fluctuations (temperature, humidity, pressure, etc.).

Storage

• The product should be stored in packaging.
• Ensure that the product is stored in the following environments where:
  - the temperature is normal and stable;
  - the relative humidity is 20 to 85% with no sudden changes in humidity and no condensation;
  - not subjected to direct sunlight;
  - not subjected to water, oil, corrosive materials, or other hazardous substances;
  - and not subjected to vibration or shock.

Maintenance

• Maintenance and inspections of the product should be done by technically qualified personnel or someone with sufficient expertise; the personnel shall be assigned at your own discretion. Otherwise, it might result in fire, burns, bodily injury, or electrical shock.
