Safety Precautions
● Read through the user guide and safety precautions before installation.
● Do not install this product in places subject to strong electric field or strong
electromagnetic wave interference.
● Before installation, make sure that the installation position is mechanically strong
enough to bear the weight of the equipment. Failure to comply may result in mechanical
hazards.
● Do not wear loose clothes or accessories during installation. Failure to comply may
result in an electric shock.
● When installing the product in a closed environment (such as a cabinet or a chassis),
cool the environment with a fan or an air conditioner to prevent overheat or fire.
● Do not modify this product.
● Do not fiddle with the bolts used to fix equipment components or the bolts marked in
red.
● When installing this product in a cabinet or terminal equipment, equip the cabinet or
terminal equipment with protective devices such as fireproof enclosures, electrical
protective enclosures, and mechanical protective enclosures with the protection level
that meets requirements of relevant IEC standards and local laws and regulations.
● Before installing equipment with strong electromagnetic interference, such as a
transformer, install an electromagnetic shielding device to prevent malfunctions of this
product.
● Install the product on incombustible objects such as metal and keep it away from
combustible materials. Failure to comply may result in a fire.
● Cover the top of the product with a piece of cloth or paper during installation to prevent
unwanted objects such as metal chippings, oil, and water from falling into the
equipment and causing faults. After installation, remove the cloth or paper to prevent
overtemperature caused by poor ventilation due to blocked ventilation holes.
● Resonance may occur when the equipment operating at a constant speed executes
variable speed operations. In this case, install the anti‑vibration rubber under the motor
frame or use the vibration suppression function to reduce the resonance.
Wiring
● Do not allow non‑professionals to perform equipment installation, wiring, maintenance,
inspection, or parts replacement.
● Cut off all power supplies before wiring. Wait for at least the time specified on the
product warning label after power‑off so that residual voltage can discharge safely.
Measure the DC voltage on the main circuit to ensure that it is within the safe voltage
range. Failure to comply may result in an electric shock.
● Do not perform wiring, remove the product cover, or touch the circuit board with power
ON. Failure to comply may result in an electric shock.
● Ensure that the product is well grounded. Failure to comply may result in an electric
shock.
