IP55 compatible models: Waterproof and dustproof performances
CAUTION:
E
● The inverter is rated with an IPX5 waterproof rating and an IP5X
the parameter unit (FR-DU08-01), the 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 ratings.
● 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 shower.
● Do not pour or apply the following liquids over the inverter: water containing soap, deter-
gent, or bath additives; sea water; swimming pool water; warm water; boiling water; etc.
● The inverter is intended for indoor
places where the inverter is subjected to direct sunlight, rain, sleet, snow, or freezing tem-
peratures.
● If the parameter unit (FR-DU08-01) is not installed, if the screws of the parameter unit are
not tightened, or if the parameter unit is damaged or deformed, the IPX5 waterproof perfor-
mance and the IP5X dustproof performance are impaired. If any abnormalities are found on
the parameter unit, 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 water-
proof 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 perfor-
mances. 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 mm 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.
General instructions
Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or par-
tially open. Never run the inverter in this status. Always replace the cover and follow instruction man-
uals when operating the inverter. For more details on the PM motor, refer to the Instruction Manual of
the PM motor.
