Disposing of the inverter
Treat as industrial waste.
Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or partially open. Never run the inverter in
this status. Always replace the cover and follow instruction manuals when operating the inverter. For more details on the PM motor,
refer to the Instruction Manual of the PM motor.
For IP55 compatible models: Waterproof and dustproof performances
The inverter is rated with an IPX5
front cover, the wiring cover, and the cable glands are securely fixed with screws.
The items enclosed with the inverter such as the Instruction Manual or CD are not rated with the IPX5 waterproof or IP5X dustproof
Although the inverter is rated with the IPX5 waterproof and IP5X dustproof ratings, it is not intended for use in water. Also, the ratings
do not guarantee protection of the inverter from needless submersion in water or being washed under strong running water such as a
Do not pour or apply the following liquids over the inverter: water containing soap, detergent, or bath additives; sea water; swimming
pool water; warm water; boiling water; etc.
The inverter is intended for indoor
sunlight, rain, sleet, snow, or freezing temperatures.
If the operation panel (FR-DU08-01) is not installed, if the screws of the operation panel are not tightened, or if the operation panel is
damaged or deformed, the IPX5 waterproof performance and the IP5X dustproof performance are impaired. If any abnormalities are
found on the operation panel, ask for an inspection and repair.
If the screws of the front cover or the wiring cover are not tightened, if any foreign matter (hair, sand grain, fiber, etc.) is stuck between
the inverter and the gasket, if the gasket is damaged, or if the front cover or the wiring cover is damaged or deformed, the IPX5
waterproof performance and the IP5X dustproof performance are impaired. If any abnormalities are found on the front cover, wiring
cover, or the gasket of the inverter, ask for an inspection and repair.
Cable glands are important components to maintain the waterproof and dustproof performances. Be sure to use cable glands of the
recommended size and shape or equivalent. The standard protective bushes cannot sufficiently maintain the IPX5 waterproof
performance and the IP5X dustproof performance.
If a cable gland is damaged or deformed, the IPX5 waterproof performance and the IP5X dustproof performance are impaired. If any
abnormalities are found on the cable glands, ask the manufacturer of the cable glands for an inspection and repair.
To maintain the waterproof and dustproof performances of the inverter, daily and periodic inspections are recommended regardless of
the presence or absence of abnormalities.
IPX5 refers to protection of the inverter functions against water jets from any direction when about 12.5-liter water (water here refers to fresh water at
room temperature (5 to 35°C)) is injected from a nozzle with an inside diameter of 6.3 mm from the distance of about 3 m for at least 3 minutes.
IP5X refers to protection of the inverter functions and maintenance of safety when the inverter is put into a stirring device containing dust of 75 μm or
smaller in diameter, stirred for 8 hours, and then removed from the device.
Indoor here refers to the environments that are not affected by climate conditions.
