Safety Instructions
3
IPX5 refers to protection of the inverter functions against water jets from
any direction when about 12.5-liter water
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.
Water here refers to fresh water at room temperature (5 to 35°C).
Indoor here refers to the environments that are not affected by climate
conditions.
CAUTION
Emergency stop
A safety backup such as an emergency brake must be
provided for devices or equipment in a system to prevent
hazardous conditions in case of failure of this product or an
external device controlling this product.
If the breaker installed on the input side of this product
trips, check for wiring faults (short circuits etc.) and damage
to internal parts of this product. The cause of the trip must
be identified and removed before turning ON the power of
the breaker.
When a protective function activates, take an appropriate
corrective action, then reset the inverter, and resume the
operation.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test on the
control circuit of the inverter. It will cause failure.
Disposal
The inverter must be treated as industrial waste.
CAUTION
Waterproof and dustproof performances
The inverter is rated with an IPX5
waterproof rating and an
IP5X
dustproof rating when the operation panel (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, detergent, or bath additives; sea
water; swimming pool water; warm water; boiling water; etc.
The inverter is intended for indoor
installation and not for
outdoor installation. Avoid places where the inverter is
subjected to direct 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.
General instruction
Many of the diagrams and drawings in the Instruction
Manual show the product without a cover or partially open
for explanation. Never operate the product in this manner.
The cover must be always reinstalled and the instruction in
the Instruction Manual must be followed when operating the
product. For more details on the PM motor, refer to the
Instruction Manual of the PM motor.
Application of caution labels
Caution labels are used to ensure safety during use of Mitsubishi
Electric inverters.
Apply the following labels to the inverter if the "retry function" and/
or "automatic restart after instantaneous power failure" have been
enabled.
For the retry function
For automatic restart after instantaneous power failure
Application of motor control labels
Apply the following labels to the inverter to avoid connecting
motors not intended for a particular motor control setting.
CAUTION
Retry Function Has
Been Selected
Stay away from the motor and machine.
They will start suddenly (after given
time has elapsed) when alarm occurs.
CAUTION
Automatic Restart after
Instantaneous Power
Failure Has Been Selected
Stay away from the motor and machine.
They will start suddenly (after reset
time has elapsed) when
instantaneous power failure occurs.
Induction motor setting
The inverter is set for the induction
motor control.
IM LED is ON during induction motor
control.
Do not drive a PM motor.
PM motor control setting
The inverter is set for the PM motor
control.
