DANGER
Ground the grounding terminals in accordance with the law in the country
concerned. Otherwise, there is a risk of electric shock and fire. Make a direct
connection without going through a circuit breaker.
Make sure that no conductive foreign objects such as screws or metal scraps, or
combustible foreign matter such as wood debris or oil, get inside the controller.
Otherwise, there is a risk of electric shock, fire, and accidents.
Never use the product in a location where water will get onto it, in a corrosive
atmosphere, or an atmosphere containing inflammable gas, or near flammable
materials. Otherwise, there is a risk of electric shock and fire.
Do not damage harnesses, apply strong forces to them, rest heavy objects on
them, trap them or bend them excessively. Otherwise, there is a risk of electric
shock and breakage.
To move this product, use the eye bolts. Hoisting it by the pump piping, for
example, will pose a danger of the product falling or overturning.
Do not install or run this product while it is damaged or has missing parts.
Otherwise, there is a risk of accidents.
CAUTION
Strictly follow the requirements for the installation environment. Otherwise, there is a risk of fire and
accidents.
Install it at a location that can bear its weight. Otherwise, there is a risk of accidents.
Do not expose terminals or other parts to static electricity. Otherwise, there is a risk of failures.
Check that the input power supply voltage is within the rated voltage range. Otherwise, there is a risk of
fire and accidents.
Check terminal pinouts and terminal codes, and make error-free connections.
Carry out withstand voltage tests at DC2 kV or lower. Applying voltages higher than this may damage
this product.
Do not perform Megger testing on control circuits. Otherwise, there is a risk of damage.
Take measures to ensure that sensors and devices in the vicinity do not malfunction due to
electromagnetic noise. Otherwise, there is a risk of accidents.
Do not subject this product to strong impacts. Otherwise, there is a risk of accidents.
Do not climb onto the product, or rest any heavy object on it. Otherwise, there is a risk of electric shock,
accidents and breakage.
humidity ranges. Otherwise, there is a risk of failures and shortening of service life.
